FIELD OF THE INVENTION
The present invention relates to recombinant nucleic acid molecules, constructs, and other agents associated with the coordinated manipulation of multiple genes in the path of fatty acid synthesis. In particular, the agents of the present are associated with the simultaneous increased expression of certain genes in the pathway of fatty acid synthesis and suppressed expression of certain different genes in the same path. The present invention also relates to plants that incorporate said agents, and in particular to plants that incorporate said constructs where the plants exhibit altered seed oil compositions.
BACKGROUND OF THE INVENTION
Vegetable oils are used in a variety of applications.
Novel vegetable oil compositions and improved methods are needed to obtain oily compositions, from bio-synthetic or natural plant sources. Depending on the use of the intended oil, several
different fatty acid compositions are desired. Plants, especially species that synthesize large quantities of oils in seeds, are an important source of oils for edible and industrial uses. Seed oils are composed almost entirely of triacylglycerols in which the fatty acids are esterified to the three hydroxyl groups of glycerol. Soybean oil typically contains approximately 16-20% saturated fatty acids: 13-16% palmitate and 3-4% stearate. See generally Gunstone et al., The lipid Handbook, Chapman & Hall, London (1994). Soybean oils have been modified by various breeding methods to create benefits for specific markets. However, soybean oil is not available that is widely beneficial to most soybean oil users such as consumers of salad oil, cooking oil and frying oil, and in commercial markets such as in markets that use biodiesel or lubricating oil. Soybean oils are either very expensive or lack an important qualitative food property such as oxidative stability, good taste of fried foods or saturated fat content, or a property of important biodiesel such as appropriate nitric oxide emitters or tolerance to Cold or cold flow. Higher plants synthesize fatty acids via a common metabolic pathway - the pathway of fatty acid synthetase (FAS), which is located in the plastids. Β-ketoacyl-ACP synthases are important important frequency limiting enzymes in cell FAS
vegetables and they exist in several versions. The ß-ketoacyl-ACP synthase I catalyses the elongation of the chain to plamitoyl-ACP (C16: 0), while the ß-ketoacyl-ACP synthase II catalyzes the chain elongation to stearoyl.ACP (C18: 0). β-ketoacyl-ACP synthase IV is a variant of β-ketoacyl-ACP synthase II, and can also catalyze chain elongation at 18: 0-ACP. In soybeans, the main products of FAS are 16: 0-ACP and 18: 0-ACP. The desaturation of 18: 0-ACP to form 18: 1 -ACP is catalyzed by a soluble delta-9 desaturase located in plastid (also referred to as "stearoyl-ACP desaturase"). See Voelker et al., 52 Annu. Rev. Plant Physiol. Plant Mol. Biol. 335-61 (2001). The FAS plastidial and delta-9 desaturase products, 16: 0-ACP, 18: 0-ACP, and 18: 1 -ACP, are hydrolyzed by specific thioesterases (FAT). Plant thioesterases can be classified into two gene families based on sequence homology and substrate preference. The first family, FATA, includes acyl-ACP long-chain thioesterases that have activity primarily in 18: 1 -ACP. Enzymes of the second family, FATB, commonly use 16: 0-ACP (palmitoyl-ACP), 18: 0-ACP (stearoyl-ACP), and 18: 0-ACP (oleoyl-ACP). Said thioesterases have an important function in the determination of chain length during the biosynthesis of de novo fatty acid in plants, and thus these enzymes are useful in providing various modifications of fatty acyl compositions, particularly with respect to the proportions relative of various fatty acyl groups that are present in storage seed oils.
The products of the FATA and FATB reactions, the free fatty acids, leave the plastids and are converted to their respective acyl-CoA esters. Acyl-CoAs are substrates for the pathway of lipid biosynthesis (Kennedy Pathway), which is located in the endoplasmic reticulum (ER). This trajectory is responsible for the lipid formation of the membrane as well as the biosynthesis of triacylglycerols, which constitute the oil of the seed. In the ER there are additional membrane binding desaturases, which can further desaturate 18: 1 to polyunsaturated fatty acids. A delta-12 desaturase (FAD2) catalyzes the insertion of a double bond in 18: 1, forming linoleic acid (18: 2). A delta-15 desaturase (FAD3) catalyzes the insertion of a double bond in 18: 2, forming linoleic acid (18: 3). Many complex biochemical trajectories have now been genetically engineered, usually through the suppression or over-expression of single genes. Further exploitation of the plant genetic manipulation potential will require the coordinated manipulation of multiple genes in one path. A number of methods have been used to combine transgenes in a plant - including sexual crossbreeding, retransformation, co-transformation, and the use of linked transgenes. A chimeric transgene with linked partial gene sequences can be used to coordinately suppress numerous plant endogenous genes. Constructs modeled on viral polyproteins can be used to simultaneously introduce multiple coding genes into plant cells. For a review, see Halpin et al., Plant Mol. Biol. 47: 295-310 (2001).
Thus, a desired plant phenotype may require the expression of one or more genes and the concurrent reduction of expression of another gene or genes. Thus, there is a need to simultaneously over-express one or more genes and suppressors, or sub-regulate, the expression of one other gene or genes in plants using a simple transgenic construct.
BRIEF DESCRIPTION OF THE INVENTION
The present invention provides a recombinant nucleic acid molecule or molecules, which when introduced into a cell or organism are capable of suppressing, at least partially reducing, reducing, substantially reducing, or effectively eliminating the expression of at least one or more FAD2 RNA., Endogenous FAD3 or FATB while at the same time co-expressing, simultaneously co-expressing, or coordinately producing one or more RNA or transcribed proteins of a gene encoding beta-ketoacyl-ACP synthase I, beta-ketoacyl-ACP synthase IV, delta-9 desaturase, or CP4 EPSPS.

"Simultaneous expression" of more than one agent such as an mRNA or protein refers to the expression of one agent at the same time as another agent. Said expression can only partially overlap and can also occur in different tissue or at different levels. "Total oil level" refers to the total aggregate amount of fatty acid without considering the type of fatty acid. As used herein, the total oil level does not include the glycerol backbone. "Transgene" refers to a nucleic acid sequence associated with the expression of a gene introduced into an organism. A transgene includes, but is not limited to, an endogenous gene or a gene not of natural origin in the organism. A "transgenic plant" is any plant that stably incorporates a transgene in a manner that facilitates the transmission of this transgene from a plant by any sexual or asexual method. An oily composition "zero saturated" contains less than
3. 6 percent saturated fatty acids. When referring to proteins and nucleic acids here, the use of ordinary capital letters, for example, "FAD2", indicates a
reference to an enzyme, protein, polypeptide, or peptide, and the use of cursive capital letters, for example, "FAD2" is used to refer to nucleic acids, including without limitation genes, cDNA, and mRNA. A cell or organism can have a family of more than one gene encoding a particular enzyme, and the capital letter that follows the terminology of the gene (A, B, C) is used to designate the family member, ie, FAD- 2-1A is a different family member of the FAD2-1B gene. As used herein, any exposed range is inclusive of the end points of the interval unless stated otherwise.
A. Agents The agents of the invention will preferably be "biologically active" with respect to a structural attribute, such as the ability of a nucleic acid molecule to hybridize to another nucleic acid molecule, or the ability of a protein to be linked by an antibody (or to compete with another molecule for said binding). Alternatively, said attribute can be catalytic and thus involves the agent's ability to mediate a chemical reaction or response. The agents will preferably be "substantially purified". The term "substantially purified" as used herein, refers to a molecule separated from substantially all other molecules normally associated with it in its native environmental conditions. More preferably a substantially purified molecule is the predominant species present in a
preparation. A purified molecule can be substantially greater than 60% free, greater than 75% free, preferably greater than 90% free, and more preferably greater than 95% free of the other molecules (exclusive of solvent) present in the natural mixture. The term "substantially purified" is not intended to include molecules present in their native environmental conditions. The agents of the invention can also be recombinants. As used herein, the term "recombinant" means any agent (eg, includes but is not limited to DNA or peptide), that is, or results, however, indirectly, from human manipulation of a nucleic acid molecule. It is also understood that the agents of the invention can be labeled with reagents that facilitate the targeting of the agent, for example, fluorescent labels, chemical labels, and / or modified bases. Agents of the invention include DNA molecules having a nucleotide sequence that is capable of being transcribed in sense and anti-sense orientations that form at least one RNA molecule that is, at least in part, double stranded. In a preferred embodiment, an agent of the invention is a double-stranded RNA molecule having a nucleotide sequence that is a fragment of FAD2, FATB or FAD2 and FATB. In another embodiment, an agent of the present invention is a DNA molecule capable of being transcribed to produce sense and antisense orientations of a nucleotide sequence in a host cell. In another embodiment, a nucleic acid molecule can have a sequence of
nucleotide in a sense orientation and in an antisense orientation, or in another embodiment, a nucleic acid molecule can have a nucleotide sequence in a sense orientation or an antisense orientation. Said nucleotide sequences can be operably linked to the same promoter, different promoters, a single promoter, or more than one promoter. Said nucleotide sequences may be in a single DNA molecule or more than one DNA molecule. Agents of the invention include nucleic acid molecules comprising a DNA sequence that is at least 50%, 60% or 70% identical over its entire length to a coding or non-coding region of the plant, or to an acid sequence nucleic that is complementary to a coding or non-coding region of the plant. More preferably they are DNA sequences which are, in their entire length, at least 80% identical, at least 85% identical, at least 90% identical; at least 95% identical, at least 97% identical; at least 98% identical, at least 99% identical or 100% identical to a coding region or non-coding region of the plant, or to a nucleic acid sequence that is complementary to a coding or non-coding region of the plant . "Identity" as is well understood in the art, is a relationship between two or more polypeptide sequences or two more nucleic acid molecule sequences, as determined by the comparison of the sequences. In the art, "identity" also means the degree of sequence relationship between polypeptide or nucleic acid molecule sequences,
as determined by the balance between chains of said sequences. "Identity" can be easily calculated by known methods including, but not limited to, those described in Computational Molecular Biology, Lesk, ed., Oxford University Press, New York 1988; Biocomputing: Informatics and Genome Projects, Smith, ed., Academic Press, New York 1993; Computer Analysis of Sequence Data, Parí I, Griffin and Griffin, eds., Humana Press, New Jersey 1994; Sequence Analysis in Molecular Biology, von Heinje, Academic Press 1987; Sequence Analysis Primer, Gribskov and Devereux, eds., Stockton Press, New York 1991; and Carillo and Lipman, SIAM J. Applied Math, 48: 1073 1988. Methods to determine identity are designed to provide the greatest balance between the sequences tested. further, methods to determine identity are encoded in publicly available programs. Computer programs which can be used to determine identity between two sequences include, but are not limited to, GCG, a series of five BLAST programs, three designed for nucleotide sequence issues (BLASTN, BLASTX, and TBLASTX) and two designed for protein sequence issues (BLASTP and TBLASTN). The BLASTX program is publicly available from NCBI and other sources, for example, BLAST Manual, AltschuI et al., NCBI NLM NIH, Bethesda, MD 20894; AltschuI et al., J. Mol. Biol. 215: 403-410 (1990). The well-known Smith Waterman algorithm can also be used to determine identity. Parameters for comparison of polypeptide sequence
they usually include the following: Algorithm: Needleman and Wunsch, J. Mol. Biol. 48: 443-453 (1970); Comparison matrix: BLOSSUM62 by Hentikofí and Hentikofí, Proc. Nati Acad. Sci. USA 89: 10915-10919 (1992); Separation Penalty 12: Gap Length Penalty: 4. A program that can be used with these parameters is publicly available as the "separation" program from Genetics Computer Group ("GCG"), Madison, Wisconsin. The above parameters together with no penalty for the final separation are omission parameters for peptide comparisons. Parameters for nucleic acid molecule sequence comparison include the following: algorithm: Needleman and Wunsch, J. Mol. Bio. 48: 443-453 (1970) Comparison matrix: equilibrium - + 10; imbalance = 0; Separation penalty: 50; Separation length penalty: 3. As used herein, "% identity" is determined using the above parameters as the default parameters for nucleic acid molecule sequence comparisons and GCG "separation" program, version 10.2 . Subsets of the nucleic acid sequences of the present invention include fent nucleic acid molecules. "Nucleic acid molecule fent" refers to a piece of a larger nucleic acid molecule, and may consist of a portion or portions significant of, or indeed greater than, the larger nucleic acid molecule. The nucleic acid molecule fent may comprise a smaller oligonucleotide having from about 15 to

In a preferred embodiment, a nucleic acid molecule has a nucleic acid sequence having at least 15, 25, 50, 100, 200, 300 or 400 contiguous nucleotides of a coding or non-coding region of the plant. In a more preferred embodiment, a nucleic acid molecule has a nucleic acid sequence that has
approximately 1, 2, 5, 10, 20, 30, 40, 50, 60, 70, 80 or 90% of the contiguous nucleotides of an entire coding or non-coding region. In a preferred embodiment, a whole coding or non-coding region can be an element of the gene selected from a whole gene, a single exon, or a single intron, a signal sequence, or a non-translated region (UTR). An element of the gene that does not have the entire sequence of an entire genetic element can be a fent of a gene element. In a genetic aspect of the present invention, a genetic element is at least 40 nucleotides in length. In one aspect of the present invention, a fent of a gene is a portion of the entire gene element and said fent contains contiguous nucleotides of about 1, 2, 5, 10, 20, 30, 40, 50, 60, 70, 80 or 90% of the entire gene element.

In a preferred embodiment, an FAD2-1 intron fragment is between about 20 and about 420, about 30 and
about 420, between about 40 and about 320, between about 50 and about 200, between about 50 and about 400, between about 50 and about 420, between about 60 and about 320, about 70 and about 220, between about 100 and about 200 , between about 100 and about 320, between about 150 and about 200, between about 150 and about 220, between about 150 and about 400, between about 200 and about 300, or between about 300 and about 400 contiguous nucleotides.

In another preferred embodiment, an intron FAD2-1 fragment is reduced in length by about 20, about 40, about 60, about 80, about 100, about 120, about 140, about 160, about 180, about 200, about 220, about 240, about 260, about 280, about 290, about 300, about 320, about 340, about 360, about 380, about 400 contiguous nucleotides with the length of SEQ ID NO: 1. For all these
fragments of intron FAD2-1, truncation or deletion can start at the 5 'end, start at the 3' end, or can be internal to an FAD2-1 intron. For all these intron fragments FAD2-1, the sequence of an intron FAD2-1 can be SEQ ID NO: 1. In a preferred embodiment, a fragment of a FA TB gene is about 80 to about 450, about 100 to about 500, about 70 to about 500, about 200 to about 400, about 150 to about 300, about 250 to about 350, about 200 to about 350 contiguous nucleotides of a FATB gene. In a preferred embodiment, a FATB fragment is derived from a half of the total nucleotides in FATB starting at the 5 'end. For all these fragments of FATB, truncation or deletion can start at the 5 'end, starting at the 3' end, or be internal to FATB. In a preferred embodiment, a fragment of FATB is derived from a half of the total nucleotides in FATB that starts at the 5 'end of FATB, is derived from a third of the total nucleotides in FATB that close at the 5' end. In a particularly preferred embodiment, a FATB fragment contains a transit peptide coding sequence, which preferably codes for the chloroplast transit peptide. In a particularly preferred embodiment, a fragment of FATB is a fragment of a transit peptide coding sequence, which preferably codes for the chloroplast transit peptide. In another modality in particular
preferred, a FATB fragment further includes about 20, about 25, about 30, about 35, 38, 39, 40, 41, 42, 43, about 45, about 50, about 55, or about 60 contiguous nucleotides of a FATB 5 'UTR. In a more preferred embodiment, a fragment includes a combination of two or more discontinuous fragments or separated gene elements, such as FATB 3'UTR fused to a FATB 5'URT. Agents of the invention include nucleic acid molecules. For example, without limitation, in one aspect of the present invention, the nucleic acid molecule of the present invention comprises an intron sequence of SEQ ID NOs: 19, 20, 21, 22, 23, 25, 32, 33, 34 , 35, 44, 45, 46 or 47 or their fragments or their complements. In another aspect of the invention, the nucleic acid molecule comprises a nucleic acid sequence, which, when introduced into a cell or organism, is capable of suppressing the production of RNA or protein while simultaneously expressing, co-expressing or co-expressing another RNA or protein. In one aspect of the invention, the nucleic acid molecule comprises a nucleic acid sequence, which when introduced into a cell or organism is capable of suppressing, at least partially reducing, reducing, substantially reducing, or effectively eliminating RNA expression. FAD2, FAD3, and / or endogenous FATB although at the same time co-expressing, simultaneously expressing, or coordinatingly expressing at least one of a beta-ketoacyl-ACP synthase I, beta-ketoacyl-ACP synthase IV, delta-9 desaturase, and / or CP4 EPSPS RNA or protein.
By suppressing, at least partially reducing, reducing, substantially reducing, or effectively eliminating the expression of at least one or more endogenous genes, the amount of FAD2 and / or FAD3 available in a plant cell is decreased, i.e. state levels Stationary protein are reduced, and a decreased percentage of polyunsaturated fatty acids such as linoleate (C18: 2) and linolenate (C18: 3) can be provided. Modifications in the fatty acid pool available for incorporation into triacylglycerols can similarly affect the composition of oils in the plant cell. In this way, a decrease in the expression of FAD2 and / or FAD3 can result in an increased proportion of monounsaturated fatty acids such as oleate (C18.1). When the amount of FATB is decreased in a plant cell, a decreased amount of saturated fatty acids such as palmitate and stearate can be provided. In this way, a decrease in the expression of FATB can result in an increased proportion of unsaturated fatty acids such as oleate (18: 1). The simultaneous suppression of FAD2, FAD3 and FATB expression results in directing the FAS path towards a complete increase in monounsaturated fatty acids of 18 carbons length, such as oleate (C18: 1). See U.S. Pat. No. 5,955,650. By increasing the amount of beta-ketoacyl-ACP synthase I (KAS I) and / or beta-ketoacyl-ACP IV synthase IV (KAS IV) available from a plant cell, a decreased percentage of 16: 0-ACP can be provided, driving to a
increased percentage of 18: 0-ACP. A greater amount of 18: 0-ACP in combination with the simultaneous suppression of one or more of FAD2, FAD3, and FATB, thereby helping to direct the oily composition towards a total increase in oleate (C18: 1). By increasing the amount of delta-9 desaturase available in a plant cell, an increased percentage of unsaturated fatty acids can be provided, resulting in a total decrease in stearate and total saturates. These combinations of increased and decreased enzyme expression can be manipulated to produce oily compositions, including fatty acids, which have an increased oleate level, decreased linoleate, linolenate, stearate, and / or palmitate levels, and a decreased total level of saturated . The increase of gene expression in plants can occur through the introduction of extra copies of gene coding sequences in the plant cell or, preferably, the incorporation of extra copies of gene coding sequences in the plant genome. Overexpression can also occur through increasing the activities of regulatory mechanisms that regulate gene expression, that is, over-regulation of gene expression. The production of CP4 EPSPS in a plant cell provides the plant cell with resistance or tolerance to glyphosate, which provides a convenient method for the successful identification of transformants via glyphosate-tolerant selection. The suppression of gene expression in plants, too
known as gene silencing, it occurs at the transcriptional level and post-transcriptional level. There are several methods for the suppression of expression of endogenous sequences in a host cell, including, but not limited to, anti-sense deletion, co-suppression, ribozymes, sense and antisense combinations (double-stranded RNAi), promoter silencing, and DNA binding proteins such as "zinc finger" zinc finger proteins (see, for example, WO 98/53083, WO 01/14538, and US Patent No. 5,759,829 (Schewmaker)). Certain of these mechanisms are associated with nucleic acid homology at the DNA or RNA level. Said homology refers to the similarity in DNA or protein sequences within the same species or between different species. Gene silencing occurs if the DNA sequence introduced into a host cell is sufficiently homologous to an endogenous gene that transcription of the introduced DNA sequence will induce silencing of the transcriptional or post transcriptional gene of the endogenous gene. Sufficient homology for the suppression of steady state expression levels can be at least 50%approximately 60%, or approximately 70% identical over the entire length of a DNA sequence to a coding region or non-coding region of the plant, or to a nucleic acid sequence that is complementary to a coding or coding region. no coding of the plant. More preferably they are DNA sequences which are, over their entire length, at least 80% identical, at least 85% identical, at least 90% identical, at least 95% identical; at least 97% identical; at least 98% identical; at least 99%
identical or 100% identical to a coding region or non-coding region of the plant, or to a nucleic acid sequence that is complementary to a coding or non-coding region of the plant. In plants, double-stranded RNA molecules can induce specific sequence silencing. Gene silencing is often referred to as double-stranded RNA ("RNAids") in plants, an RNA or RNAi interference in Caenorhabditis elegants and in animals, and as chelation in fungi. In a preferred embodiment, the nucleic acid molecule of the present invention comprises a first set of DNA sequences, each of which exhibits sufficient homology to one or more coding or non-coding sequences of a plant gene such that when expresses, is capable of effectively removing, substantially reducing, or at least partially reducing the level of a mRNA or protein transcript encoded by the gene from which the coding or non-coding sequence is derived, or any gene having homology to the sequence of coding or non-coding of the objective. In a preferred embodiment, the nucleic acid molecule of the present invention comprises (a) a first set of DNA sequences, each of which exhibits sufficient homology to one or more coding or non-coding sequences of a plant gene such that when expressed, it is capable of effectively eliminating, substantially reducing, or at least partially reducing the level of a mRNA or protein transcript
encoded by the gene from which the coding or non-coding sequence is derived, or any gene which has homology to the non-coding sequence of the target, and (b) a second set of DNA sequences, each of which exhibits sufficient homology to a plant gene so that when expressed, it is capable of at least partially increasing, increasing, increasing, or substantially increasing the level of a mRNA or protein transcript encoded by the gene. As used herein, "a set" of DNA sequences may be one or more sequences, which encode or do not code for a protein. For example, a first set of DNA sequences can be composed of only one promoter, one non-coding region, and one terminator. A second set of DNA sequences may or may not be present after or before the first set of DNA sequences. As used herein, "a reduction" in the level or amount of an agent such as a protein or mRNA means that the level or amounts are reduced relative to a cell or organism lacking an ADBN sequence capable of reducing the agent. For example, "at least a partial reduction" refers to a reduction of at least 25%, "a substantial reduction" refers to a reduction of at least 75%, and "an effective elimination" refers to a reduction of more than of 95%, all reductions which in the level or amount of the agent are relative to a cell or organism lacking a DNA sequence capable of reducing the agent. As used herein, a level or amount "increased" or
"increased" of an agent such as a protein or mRNA means that the level or amount is higher than the level or amount of the agent present in a cell, tissue or plant with a similar genetic background but lacking a nucleic acid molecule introduced that encodes the protein or mRNA. For example, a "at least partially increased" level refers to an increase of at least 25%, and a "substantially increased" level refers to an increase of at least 100%, all increases in the level or amount of a agent are relative to the level or amount of agent that is present in a cell, tissue or plant with a similar genetic background but lacks an introduced nucleic acid molecule encoding the protein or mRNA. In a preferred embodiment, an increase in expression can be any expression where the protein is heterologous to the system. For example, any expression of CP4 EPSPS can be an increase in expression if there is no expression in the plant before for the introduction of a nucleic acid molecule encoding the protein. When the levels of an agent are compared, such a comparison is preferably carried out between organisms with a similar genetic background. Preferably, a similar genetic background is a background where the organisms are shared compared to 50% or more, more preferably 75% or more, and, even more preferably 90% or more of sequence identity of the nuclear genetic material. In another preferred aspect, a similar genetic background is a background where the organisms that are compared are plants, and the plants are isogenic except for any
genetic material originally introduced using plant transformation techniques. Measurements of the level or amount of an agent can be carried out by any suitable method, non-limiting examples of which include comparison of mRNA transcript levels, protein or peptide levels, and / or phenotype, especially oil content. As used herein, mRNA transcripts include processed or unprocessed mRNA transcripts, and proteins or peptides include proteins or peptides with or without any post-translational modification. The DNA sequences of the first set of DNA sequences can be coding sequences, intron sequences, 3'UTR sequences, 5'UTR sequences, promoter sequences, other non-coding sequences, or any combination of the above. The first set of DNA sequences encoding one or more sequences which, when expressed, are capable of selectively reducing either or both of the protein and the transcript encoded by a gene selected from the group consisting of FAD2, FAD3 and FATB. In a preferred embodiment, the first set of DNA sequences is capable of expressing the antisense RNA, in which the individual antisense sequences can be linked in a transcript, or they can be in unbound individual transcripts. In a further preferred embodiment, the first set of DNA sequences are physically linked sequences that are capable of expressing a single dsRNA molecule. In a different preferred embodiment, the first set of DNA sequences is capable of expressing sense co-deletion RNA, in the
which individual sense sequences can be linked in a transcript, or they can be in unbound individual transcripts. Exemplary embodiments of the first set of DNA sequences are described in part B of the detailed description, and in the examples. The second set of DNA sequences encodes one or more sequences of which, when expressed, are capable of increasing either or both of the protein and transcript encoded by a gene selected from the group consisting of synthase I beta-ketoacyl-ACP ( KAS I), synthase IV beta-ketoacyl-ACP (KAS IV), delta-9 desaturase, and CP4 EPSPS. The DNA sequences of the second set of DNA sequences can be physically linked sequences. Exemplary embodiments of the second set of DNA sequences are described below in Parts C and D of the detailed description. In this manner, the present invention provides methods for altering the composition of fatty acids and compounds containing said fatty acids, such as oils, waxes and fats. The present invention also provides methods for the production of particular fatty acids in host cell plants. Said methods employ the use of expression cassettes described herein for the modification of the FAS path of host plant cell.

The DNA sequences of the first set of DNA sequences transcribe RNA sequences or RNA fragments that exhibit at least 90%, preferably at least 95%, more preferably at least 98%, or more preferably 100% identity for a coding or non-coding region derived from the gene which is to be deleted. Said percent identity can be compared to another nucleic acid fragment. Preferably, the non-coding sequence is about 3'UTR, 5'UTR, a fraction of a protein coding sequence or a
intron of a plant gene. More preferably, the non-coding sequence is a 3'UTR, 5'UTR promoter sequence, or an intron of a plant gene.

Preferably each sequence in the first set of DNA sequences is capable, when expressed, of suppressing the expression of a different gene, including without limitation different gene family members. The sequences may include coding sequences, intron sequences, 3'UTR sequences, 5'UTR sequences, other coding sequences or any combination of the above. The first set of DNA sequences can be expressed in any available form, including as a dsRNA construct, a sense cosuppression construct, or as an antisense construct.

Preferred promoters include, but are not limited to, a napin promoter, a 7Sa promoter, a 7Sa 'promoter, an arcelin promoter, or an FAD2-1A promoter. The second set of DNA sequences comprises coding sequences, each of which is a DNA sequence encoding a sequence that when expressed is capable of increasing one or both of the protein and transcript encoded by a gene selected from the group that consists of KAS I, KAS IV, delta 9 desaturase, and CP4 EPSPS. Each coding sequence is associated with a promoter, which can be any functional promoter in a plant, or any plant promoter.

Preferred specific seed promoters, include, but are not limited to, a napin promoter, a 7Sa promoter, a 7Sa promoter, an arcelin promoter, a delta-9 desaturase promoter; or a FAD2-1A promoter. In the embodiments depicted in Figures 1 and 2, the first set of DNA sequences, when expressed, is capable of forming a dsRNA molecule that is capable of suppressing the expression of one or both of the protein and transcript encoded by, or transcribed from, a gene selected from the group consisting of FAD2, FAD3 and FATB. The first set of DNA sequences depicted in Figure 1 comprises three non-coding sequences, each of which expresses an RNA sequence (not shown) that exhibits identity for a non-coding region of a gene selected from the group that consists of FAD2, FAD3 and FATB genes. The non-coding sequences each express an RNA sequence exhibiting at least 90% identity for a non-coding region of a gene selected from the group consisting of FAD2, FAD3 and FATB genes. The first set of DNA sequences also comprises three antisense sequences, each of which expresses an antisense RNA sequence (not shown) which is capable of forming a double stranded RNA molecule with its respective corresponding RNA sequence (as is expressed by non-coding sequences). The non-coding sequences can be separated from the
antisense sequences by a spacer sequence, preferably one that promotes the formation of a dsRNA molecule. Examples of such spacer sequences include those set forth in Wesley et al., Plant J., 27 (6): 581-90 (2001), and Hamilton et al., Plant J., 75: 737-746 (1988).

A non-limiting example of a particularly preferred splice intron is intron # 5 FAD3. The non-coding, sense-oriented molecules can optionally be separated from the corresponding antisense oriented molecules by a DNA spacer segment. The segment
Spacer can be a gene fragment or artificial DNA. The spacer segment may be short to facilitate the formation of hairpin dsRNAs or so long as to facilitate dsRNA without a hairpin structure. The spacer can be provided by extending the length of one of the sense or antisense molecules as described in US 2005/0176670. Alternatively, a right-edge-right-edge sequence ("RB-RB") can be created after insertion into the plant genome as described in the U.S. patent application. 2005/0183170. Referring now to Figure 1, the nucleic acid molecule comprises two regions of T-DNA, each of which is flanked by a right border and a left border.

The first and second sets of DNA sequences are all located in the region of
Unique T-DNA. In the embodiments that express dsRNAs shown in Figures 1 and 2, the order of the sequences can be alternating from the illustrated and described, however the non-coding sequences and the antisense sequences are preferably arranged around the spacer sequence such that, when expressed, the first non-coding sequence can hybridize to the first antisense sequence, the second non-coding sequence can hybridize to the second antisense sequence, and the third non-coding sequence can hybridize to the third antisense sequence such that one molecule of single dsRNA can be formed. Preferably the non-coding sequences are in a sense orientation, and the antisense sequences are in an antisense orientation relative to the promoter. The numbers of non-coding, antisense and coding sequences, and their various relative positions in the T-DNA region (s) can also be altered in a manner suitable to achieve the objects of the present invention. Referring now to Figures 3 and 4, the illustrated nucleic acid molecule comprises a T-DNA region flanked by a right border and a left border, in which the first and second sets of DNA sequences are located.

The non-coding sequences each express an RNA sequence exhibiting at least 90% identity for one or more non-coding regions of a gene selected from the group consisting of FAD2, FAD3 and FATB genes. The order of the non-coding sequences within the first set of DNA sequences can be altered from that illustrated and described herein, but the non-coding sequences are arranged
in a meaning sense relative to the promoter. Figure 4 depicts an embodiment in which the first set of DNA sequences, when expressed, is capable of forming an antisense construct that is capable of suppressing the expression of one or more proteins or transcripts encoded by, or derived from, a gene selected from the group consisting of FAD2, FAD3, and FATB. The first set of DNA sequences comprises three antisense sequences, each of which expresses an antisense RNA sequence (not shown) that exhibits identity for one or more non-coding regions of a gene selected from the group consisting of FAD2 genes, FAD3, and FATB.

Agrobacterium-mediated transfer is a widely applicable system for the introduction of genes into plant cells. See, for example, Fraley et al., Bio / Technology 3: 629-635 (1985); Rogers et al., Methods Enzymol. 153: 253-277 (1987). The region of DNA to be transferred is defined by the border sequences and DNA intervention is usually inserted into the plant genome. Spielmann et al., Mol. Gen. Genet. 205: 34 (1986).

G. Oily compositions For many oily applications, saturated fatty acid levels are preferably less than 8% by weight, and more preferably approximately 2-3% by weight. Saturated fatty acids have high melting points which are undesirable in many applications. When used as a raw material or fuel, saturated fatty acids cause turbidity at low temperatures, and confer poor cold flow properties such as pour points and cold filter plugging points for fuel. Oil products that contain low saturated fatty acid levels may be preferred by consumers and the food industry because they are perceived as healthy and / or can be labeled "free of saturated fat" according to FDA guidelines. In addition, low saturated oils reduce or eliminate the need to winterize oil for food applications such as salty oils. In biodiesel and lubricant applications, oils with low saturated fatty acid levels confer improved cold flow properties and do not cloud at low temperatures. The factors that govern the physical properties of a particular oil are complex. Palmitic acid, stearic acid and other saturated fatty acids are usually solid at room temperature, in contrast to unsaturated fatty acids, which remain liquid. Because
the saturated fatty acids do not have double bonds in the acyl chain, they remain stable for oxidation at elevated temperatures. Saturated fatty acids are important components in margarine and chocolate formulations, but for many food applications, reduced levels of saturated fatty acids are desired. Oleic acid has a double bond, but is relatively stable at high temperatures, and oils with high levels of oleic acid are suitable for cooking and other procedures where heating is required. Recently, the increased consumption of high oleic oils has been recommended, because oleic acid appears to lower blood levels of low density lipoproteins ("LDL") without affecting the high density lipoprotein ("HDL") levels. However, some limitation of oleic acid levels is desirable, because when oleic acid degrades at high temperatures, it creates negative taste compounds and decreases the positive flavors created by the oxidation of linoleic acid. Neff et al., JAOCS, 77: 1303-1313 (2000); Warner et al., J. Agrie. Food Chem. 49: 899-905 (2001). Preferred oils have oleic acid levels that are 65-85% or less by weight, in order to limit abnormal flavors in food applications such as frying oil and fried foods. Other preferred oils have oleic acid levels that are greater than 55% by weight in order to improve oxidative stability. Linoleic acid is a major polyunsaturated fatty acid in foods and is an essential nutrient for humans. It is a component
desirable for many food applications because it is a major precursor of fried food flavor substances such as 2,4-decadienal, which makes good taste in fried foods. However, linoleic acid has limited stability when heated. Preferred food oils have levels of linoleic acid that are 10% or more by weight, to increase the formation of desirable fried food flavoring substances and are also 25% or less by weight, so that the formation of abnormal flavors is reduced. Linoleic acid also has cholesterol lowering properties, although dietary excess can reduce the ability of human cells to protect themselves from oxidative damage, thereby increasing the risk of cardiovascular disease. Toborek et al., Am J. Clin. J. 75: 1 19-125 (2002). See generally Flavor Chemistry of Lipid Foods, editors D.B. Min & T.H. Smouse, Am Oil Chem. Soc, Champaign, IL (1989). Linoleic acid has a lower melting point than oleic acid, it also contributes to improving the desirable cold flow properties in biodiesel and biolubricant applications. Preferred oils for more applications have linoleic acid levels of 30% or less by weight, because the oxidation of linoleic acid limits the useful storage or time of use of the oil for frying, food, food, and lubricating products. See generally Physical Properties of Fats, Oils, and Emulsifiers, ed. N. Widlak, AOCS Press (1999); Erhan & Asadauskas, Lubricant Basestocks from Vegetable Oils, Industrial Crops and Products, 1 1: 277-282 (2000). In addition, high levels of linoleic acid in livestock feed can lead to
undesirable high levels of linoleic acid in the milk of the daily cattle, and therefore oxidative stability and deficient flavor. Timmons et al., J. Dairy Sci. 84: 2440-2449 (2001). An oily composition useful widely has linoleic acid levels of 10-25% by weight. Linolenic acid is also an important component of the human diet. It is used to synthesize the? -3 family of long chain fatty acids and the prostaglandins derived from them. However, their double bonds are highly susceptible to oxidation, so that oils with high levels of linolenic acid deteriorate rapidly on exposure to air, especially at high temperatures. Partial hydrogenation of such oils is often necessary before they can be used in food products to retard the formation of abnormal flavors and rancidity when the oil is heated, but hydrogenation creates unhealthy trans fatty acids that contribute to cardiovascular disease. To achieve improved oxidative stability, and reduce the need for hydrogenated oil, preferred oils have linolenic acid levels that are 8% or less by weight, 6% or less, 4% or less, less than about 3%, and more preferably 0.5. -2% by weight of the total fatty acids in the oil of the present invention. Soybean oil of the present invention can also be used as a mixing source to make a mixed oil product. By a mixing source, it means that the oil of a soybean seed of the present invention can be mixed with other oils
vegetables to improve the characteristics, such as fatty acid composition, taste, and oxidative stability, of the other oils. The amount of oil of a soybean seed of the present invention that can be used will depend on the properties sought to be achieved in the resulting final mixed oil product. Examples of oil products include, but are not limited to, margarines, fat to make the pastry more friable, oils for frying, salty oils, etc. The oil of a soybean seed of the present invention may be a mixed oil, synthesized oil or in a preferred embodiment an oil generated from an oleaginase having an appropriate oily composition. An oil generated directly from a soybean seed is an unmixed oil. In another aspect, an oil is directly from a mature soybean seed. In this regard, a mature seed as defined by a seed that is harvested in the field for commercial agricultural practices, such as sale for food. In a preferred embodiment, the oil is a soybean oil. The oil can be a crude oil such as crude soybean oil, or it can be a processed oil, for example the oil can be refined, bleached, deodorized and / or conditioned for winter. As used herein, "refinement" refers to a process for treating natural or processed fat or oil to remove impurities, and can be performed by the treatment of grease or oil with caustic soda, followed by centrifugation, washing with water, and heating under vacuum. "Whitening" refers to a procedure for the treatment of fat or oil to remove or reduce
levels of coloring materials in the grease or oil. Whitening can be done by treating fat or oil with activated charcoal or fuller's earth (diatomaceous earth). "Deodorization" refers to a process of removing components of a grease or oil that contributes objectionable flavors or odors to the final product, and can be accomplished by the use of high vacuum and superheated steam washing. "Conditioning for winter" refers to a procedure for removing saturated glycerides from an oil, and can be performed by cooling and removing from the solidified portions of an oil fat.

An oil of the present invention is particularly suitable for use as an oil for cooking or frying. Due to its reduced polyunsaturated fatty acid content, the oil of the present invention does not require excessive processing of customary oils because some objectionable odors and coloring compounds are present. In addition, the low saturated fatty acid content of the present oil improves the cold flow properties of the oil, and obviates the need to heat the stored oil to prevent it from crystallization or solidification. The improved cold flow also increases drainage of the oil from the fried food material once it has been removed from the frying oil, resulting in a lower fat product. See Bouchon et al., J. Food Science 66: 918-923 (2001). the low levels of linolenic acid in the present oil are particularly advantageous in frying to reduce abnormal flavors. The present oil is also well suited for use as a salty oil (an oil that maintains clarity at refrigerator temperatures of 40-50 degrees Fahrenheit). Its clarity improves at refrigeration temperatures, due to its low saturated fatty acid and moderate linoleic acid content, reducing or eliminating the need to winterize the oil before use as a salty oil. In addition, the low linoleic and low linoleic acid content of the present oil makes it well suited for the production of fat to make the most friable pastry, margarine and other semi-solid vegetable fats used in foods. The production of these fats involves
usually hydrogenation of unsaturated oils such as soybean oil, corn oil, or canola oil. The increased oxidation and flavor stability of the present oil means that it does not need to be hydrogenated to the extent that the typical vegetable oil is for uses such as margarine and fat to make the pastry more friable, thereby reducing the processing costs and the production of unhealthy trans isomers. An oil of the present invention is also suitable for use as a raw material for producing biodiesel, particularly since the biodiesel made from said oil has improved cold flow, improved ignition quality (cetane number), improved oxidative stability, and emissions of reduced nitric oxide. Biodiesel is an alternative diesel fuel usually comprised of methyl esters of C16-C22 saturated, monounsaturated and polyunsaturated fatty acids. The cetane number is a measure of ignition quality - the shortest ignition delay time of fuel in the engine, the highest cetane number. The ASTM standard specification for biodiesel fuel (D 6751 -02) requires a minimum cetane number of 47. The use of biodiesel in conventional diesel engines results in substantial reductions of contaminants such as sulfates, carbon monoxide and particulates compared to fuel of diesel oil, and the use in school buses can greatly expose children to toxic diesel exhaust gases. A limitation for the use of 100% conventional biodiesel as fuel is the point of
high turbidity of conventional soybean biodiesel (2 degrees C) compared to diesel number 2 (-16 degrees C). Dunn et al., Recent. Res. Devel. in OH Chem., 1: 31 -56 (1997). The biodiesel made from the oil of the present invention has a (reduced) cloud point and improved cold filter plugging point, and can also be used in blends to improve the cold temperature properties of biodiesel made from highly saturated but inexpensive sources. fat such as animal fats (bait, lard, chicken fat) and palm oil. Biodiesel can also be mixed with petroleum diesel at any level. Biodiesel is typically obtained by the extraction, filtration and refining of soybeans to remove free fats and phospholipids, and then transesterification of the oil with methanol to form methyl esters of fatty acids. See, for example, the U.S. Patent. No. 5,891, 203. The resulting soy methyl esters are commonly referred to as "biodiesel". The oil of the present invention can also be used as a diesel fuel without the formation of methyl esters, such as, for example, the acetal mixtures with the oil. See, for example, the patent of E.U.A. No. 6,013.1 14. Due to its improved cold flow and oxidative stability properties, the oil of the present invention is also useful as a lubricant, and as a diesel fuel additive. See, for example, the Patents of E.U.A. Nos. 5,888,947, 5,454,842 and 4,557,734. Soybeans and oils of the present invention are also
suitable for use in a variety of soy foods made from whole soybeans, such as soy milk, soy nut butter, natto, and tempeh, and soy foods made from processed soybeans and soybean oil. soybeans, which include soybean meal, soybean meal, soy protein concentrate, soy protein isolates, textured soy protein concentrate, hydrolyzed soy protein, chantilly custard, cooking oil, salty oil, fat to make the most friable pastry and lecithin. Whole soybeans are also edible, and are usually sold to raw, toasted or edamame consumers. Soy milk is usually produced by wetting and crushing whole soybeans, it can be consumed as it is, spray dried or processed to form soy yogurt, tofu, tofu, or yuba. The soybean or oil present can be advantageously used in these and other soy foods because of its improved oxidative stability, the reduction of abnormal taste precursors, and its low saturated fatty acid level.
G. Suppression Modulation Another embodiment of the invention is directed to a method of modulating gene suppression levels. The modulation of gene suppression can result in more or less gene deletion. The deletion of a gene product can be the result of insertion of a construct of the present invention into a plant genome. Similarly, modulation
of gene deletion can result from insertion of a construct of the present invention into a plant genome. Other examples of methods for modulating gene suppression include, without limitation, antisense techniques, co-suppression, RNA interference (RNAids), transgenic animals, hybrids, and ribozymes using a construct of the present invention. The following examples are provided by way of illustration, and are not intended to be limiting of the present invention. Deletion of a gene can be modulated by altering the length of the transcribable DNA used for deletion, whose sequence is derived from the gene targeted for suppression. Many methods can be used for suppression of a gene that uses post-transcriptional gene silencing mechanisms. Without being limited by theory, these methods are believed to have in common the expression of an RNA molecule that hybridizes to another RNA molecule. Surprisingly, it may be advantages to use an RNA molecule of particular lengths to modulate or moderate the suppression of steady state expression levels of an endogenous target gene. The deletion of FAD2-1 gene leads to high levels of oleic acid and reduction of linoleic acid levels. When FAD2-1 is heavily suppressed, oleic acid levels may be greater than 65%, which causes a reduction in palmitic acid and linoleic acid levels. For example, when FAD2-1 is suppressed, oleic acid levels can reach 85% and palmitic and stearic acid levels are reduced to
approximately 10%. Similarly, the down regulation of FATB results in decreased levels of saturated fatty acids, primarily palmitate. When FAD2 and FATB are suppressed so that the levels are approximately 85%, the saturates levels are approximately 10%. When FAD2 and FATB are suppressed so that oleic levels are greater than 85%, saturated levels can fall below 10%. In view of the present invention, saturation levels can be reduced to less than 10% without increasing the oleic acids above 85%. In another embodiment, the suppression of FAD2 is modulated by reducing the intron length of FAD2-1 induced in the plant. Less suppression of FAD2 results at moderate levels of oleic acid, approximately 40-85% oleic acid. The deletion of FAD2 is reduced as the length of introduced FAD2-1 intron fragment is reduced. For example, an FAD2-1 intron reduced in length by at least 100 contiguous nucleotides can reduce the suppression of FAD2 and the corresponding increase in oleic acid and decrease in levels of linoleic acid. The relationship between the decrease in deletion of endogenous gene and decrease in length of homologous DNA can be determined empirically by introducing different DNA lengths. For example, the amount of reduction in suppression obtainable by reducing the length of homologous introduced DNA can be determined by deleting increased portions of homologous DNA that are introduced and assayed for target gene expression.
Included in the present invention is a method for moderating the suppression of FAD2 although it still has a strong reduction of saturated levels in a plant. In these plants, oleic acid levels can vary from 40-85%. Similarly, less than complete suppression of FATB occurs when the combined 3 'and 5' untranslated regions are introduced as compared to when the full-length FATB gene is introduced into a host cell. In a similar way, levels of FATB suppression are reduced when the 5 'part of the open reading frame, which encodes mainly the chloroplast transit peptide, is introduced into a host cell. In cells with deleted FAD2 and FATB using methods according to the present invention, the levels of oleic acid can be 40-85% although the saturated levels can be between 1 to 9 percent. In one embodiment, the present invention is directed to a method for modulating gene suppression to reduce deletion relative to the deletion of a whole gene element, where an entire gene element can be a whole gene, an entire exon, a whole intron, a whole signal sequence, or a whole UTR, then constructing a recombinant nucleic acid molecule comprising a fragment of the endogenous sequence of the gene element; initiating the expression of the recombinant nucleic acid molecule in a host cell; and the suppression of the endogenous gene with recombinant acid molecule. The gene that is deleted can be any gene, including FAD2 and FATB. In one modality, the present
invention is directed to a method for modulating the suppression of FAD2 or FATB which comprises: expressing an element sequence of the FAD2 gene or partial FATB in host cell, wherein an element of the FAD2 or FATB gene is of an endogenous FAD2 or FATB gene in the host cell and an element sequence of the FAD2 or FATB gene can be an FAD2 or FATB gene, an FAD2 or FATB exon, an FAD2 intron or FATB, a coding region of the FAD2 transit peptide or FATB, or a FAD2 UTR or FATB; and the element sequence of the FAD2 gene or partial FATB is smaller than the element sequence of the FAD2 gene or whole FATB; and suppressing an endogenous FAD2 or FATB with the FAD2 gene element sequence or partial FATB, where the deletion levels of the endogenous FAD2 gene or FATB in the host cell are lower than the levels of endogenous gene FAD2 or FATB deletion in a cell host with a similar genetic background and a second FAD2 or FATB nucleic acid sequence comprising the element sequence of the FAD2 gene or whole FATB of the FAD2 or FATB gene element. In another embodiment, the present invention is directed to a method of altering the oily composition of a plant cell by transforming a plant cell with a recombinant nucleic acid molecule comprising a DNA sequence that suppresses the endogenous expression of FAD2, FATB or FAD2 and FATB where the DNA sequence comprises a nucleic acid sequence of FAD2, FATB or FAD2 and FATB that is shorter than the entire sequence of an entire genetic element selected from a gene, an exon, an intron, a region coding
of transit peptide, about 3'UTR, about 5'-UTR and an open reading frame; and the growth of the plant cell under conditions where the transcription of said DNA sequence is initiated, whereby the oily composition is altered in relation to a plant cell with a similar genetic background but lacks the recombinant nucleic acid molecule. An element of the FAD2 or FATB gene can be shortened in length by 50, 75, 100, 150, 175, 200, 250, 300, 350, 400, 450, 500, 600, 800, 1000, 2000, 3000 or 4000 nucleotides . A length of an element of the FAD2 or FATB gene may be 50, 75, 100, 150, 175, 200, 220, 250, 300, 320, 350, 400, 420, 450, 500, 550, 600, 800 or 1000 nucleotides. In another embodiment, the present invention is directed to a method of increasing the content of oleic acid and reducing the content of saturated fatty acid in a plant seed by: i) shortening the length of an exogenous FAD2 DNA sequence in a host cell until the amount of FAD2 expression suppression of a transformed plant is at least partially reduced in relation to the suppression of FAD2 expression in host cell with a similar genetic background and an entire exogenous FAD2 gene DNA sequence; and ii) growth of a plant with a nucleic acid molecule comprising the shortened FAD2 DNA sequence, wherein the shortened FAD2 DNA sequence at least partially suppresses the endogenous expression of FAD2; and ii) cultivate a plant that produces seed with a reduced saturated fatty acid content in relation to the seed of a plant that has a similar genetic background but
that lacks the shortened DNA FAD2 sequence. The amount that the exogenous FAD2 DNA sequence is shortened to at least partially reduce the suppression of endogenous FAD2 that can be determined empirically by introducing different lengths of DNA. For example, the amount of reduction in suppression obtainable by reducing the length of homologous introduced DNA can be determined by suppressing increased portions of homologous DNA that is introduced and assayed for expression of the target gene. The amount of FAD2 expression suppression can be obtained as an average of three or more, six or more, ten or more, fifteen or more, or twenty or more seeds of a plant. In another embodiment, the present invention is directed to a method of producing a transformed plant having seed with a reduced saturated fatty acid content by transforming a plant cell with a recombinant nucleic acid molecule comprising a DNA sequence that suppresses the endogenous expression of FAD2 and FATB, wherein the DNA sequence comprises an FAD2 nucleic acid sequence that is shorter than the entire sequence of a whole genetic element selected from a gene, an exon, an intron, a transit peptide coding region.; and some UTR; and the growth of the transformed plant, wherein the transformed plant produces seed with a reduced saturated fatty acid content in relation to the seed of a plant having a similar genetic background but lacking said recombinant nucleic acid molecule.
In another embodiment, the present invention is directed to a method of modulating the fatty acid composition of oil from a seed of a temperate oleaginous culture by isolating a genetic element of at least 40 nucleotides in length which is capable of suppressing the expression of an endogenous gene in the path of fatty acid synthesis; generating more than one shortened fragment of the genetic element; introducing each of more than one of the shortened fragments into a plant cell of the temperate oleaginous culture to produce transgenic plants; and selecting a transgenic plant comprising a shortened fragment of determined length and sequence that effects a desirable change in the fatty acid composition of seed oil. In a preferred embodiment, the above method also includes the construction of a recombinant DNA construct having at least two shortened fragments of two different different endogens that effect different desirable changes in the fatty acid composition of seed oil; introducing the recombinant DNA construct into a plant cell of the temperate oleaginous culture to produce transgenic plants; and selecting a transgenic plant comprising at least two shortened fragments and an oil fatty acid composition of a seed having more than one desirable change effected by at least two shortened fragments. In another embodiment, the present invention is directed to a soybean that exhibits an oil composition having a strongly reduced saturated fatty acid content and an oleic acid content.

A contiguous sequence of soy FATB-2 cDNA (SEO ID NO: 42) is used to designate thirteen oligonucleotides that extend the gene: F1 (SEQ ID NO: 48), F2 (SEO ID NO: 49), F3 (SEO ID) NO: 50), F4 (SEQ ID NO: 51), F5 (SEQ ID NO: 52), F6 (SEQ ID NO: 53), F7 (SEQ ID NO: 54), R1 (SEQ ID NO: 55), R2 (SEQ ID NO: 56), R3 (SEQ ID NO: 57), R4 (SEQ ID NO: 58), R5 (SEQ ID NO: 59), and R6 (SEQ ID NO: 60). Oligonucleotides are used in pairs for PCR amplification of isolated soybean genomic DNA: pair 1 (F1 + R1), pair 2 (F2 + R1), pair 3 (F3 + R2), pair 4 (F4 + R3), pair 5 (F5 + R4), par 6
(F6 + R5), and par 7 (F7 + R6). The PCR amplification of par 5 is carried out as follows: 1 cycle, 95 ° C for 10 minutes; 30 cycles, 95 ° C for 15 seconds, 43 ° C for 30 seconds, 72 ° C for 45 seconds; 1 cycle, 72 ° C for 7 minutes. For all other oligo pairs, PCR amplifications are carried out as follows: 1 cycle, 95 ° C for 10 minutes; 30 cycles 95 ° C for 15 seconds, 48 ° C for 30 seconds, 72 ° C for 45 seconds; 1 cycle, 72 ° C for 7 minutes. Positive fragments are obtained from the first pairs 1, 2, 4, 5, 6 and 7. Each fragment is cloned in vector pCR2.1 (Invitrogen). Fragments 2, 4, 5 and 6 are confirmed and sequenced. These four sequences are aligned to form a genomic sequence for the FATB-2 gene (SEQ ID NO: 43). Four introns are identified in the soybean FATB-2 gene by comparison of the genomic sequence to the cDNA sequence; intron 1 (SEQ ID NO: 44) the base 1 19 is expanded to the base 1333 of the genomic sequence (SEQ ID NO: 43) and is 1215 bp in length; intron II (SEQ ID NO: 45) expands base 2231 to base 2568 of the genomic sequence (SEQ ID NO: 43) and is 338 bp in length; intron III (SEQ ID NO: 46) expands base 2702 to base 3342 of the genomic sequence (SEQ ID NO: 43) and is 641 bp in length; and intron IV (SEQ ID NO: 47) expands base 3457 to base 3823 of the genomic sequence (SEQ ID NO: 43) and is 367 bp in length.
EXAMPLE 2 Suppression constructs
2A. Constructs FAD2-1 Intron # 1 FAD2-1 A (SEQ ID NO: 1) is cloned into the expression cassette, pCGN3892, in sense and antisense orientations. The vector pCGN3892 contains the soybean 7S promoter and a rbcS 3 'pea. Both gene fusions are then ligated separately into pCGN3892, a vector containing the CP4 EPSPS gene regulated by the FMV promoter. The resulting expression constructs (sense pCGN5469 and antisense pCGN5471) are used for the transformation of the soybean seed. Intron FAD2-1 B (SEQ ID NO: 2) is fused at the 3 'end of intron # 1 FAD2-1 A in plasmid pCGN5468 (contains the soybean 7S promoter fused to the FAD2-1 A intron ( sense) and a rbcS 3 'pea) or pCGN5470 (contains the soybean 7S promoter fused to the FAD2-1 A intron (antisense) and a rbcS 3' vetch) in sense and antisense orientation, respectively. The resulting intron combination fusions are then ligated separately into pCGN9372, a vector containing the CP4 EPSPS gene regulated by the FMV promoter. The resulting expression constructs (pCGN5485, intron sense FAD2-1 A & FAD2-1 B and intron antisense pCGN5486, FAD2-A &FAD2-1 B) are used for the transformation of soybean seed.

2 C. Constructos FatB The intron sequence II FATB-1 of soybean (SEQ ID NO:
30) is amplified via PCR using a partial genomic clone FATB-1 as a template. The PCR amplification is carried out as follows: 1 cycle 95 ° C for 10 minutes, 25 cycles, 95 ° C for 30 seconds, 62 ° C for 30 seconds, 72 ° C for 30 seconds; 1 cycle, 72 ° C for 7 minutes. The PCR amplification results in a product that is 854 bp long, which includes restriction sites redesigned at both ends. The PCR product is cloned directly into the expression cassette pCGN3892 in sense orientation, as Xho sites designed at the 5 'end of the primers PCR, to form pMON70674. The vector pCGN3892 contains the soybean 7S promoter and a rbcS 3 'pea. pMON70674 is then cut with Noñ and ligated into pMON41 164, a vector containing the CP4 EPSPS gene regulated by the FMV promoter. The resulting gene expression construct, pMON70678, is used for the transformation of soybean using Agrobacterium methods. Two other expression constructs containing the intron II FATB-1 sequence (SEQ ID NO: 30) are created. pMON70674 is cut with Noñ and ligated into pMON70675 containing the CP4 EPSPS gene regulated by the FMV promoter and the KAS IV gene regulated by the napin promoter, resulting in pMON70680. The expression vector pMON70680 is then cut with SnaBly and ligated with a gene fusion of the delta-9 humpback desaturase gene (SEQ ID NO: 41) in sense orientation regulated by the 7S promoter. The expression constructs pMON70680 and pMON70681 are used for the tranfromation of soybean using Agrobacterium methods.
2D Combination Constructs Expression constructs are made by containing several permutations of a first set of DNA sequences. The first set of DNA sequences are any of those described, or illustrated in Figures 5A-5D and 6A-6C, or any other set of DNA sequences containing various combinations of coding regions or non-coding FAD2, FAD3 and FATB sense or antisense,
antisense sense so that they are capable of the formation of dsRNA constructs, sense co-deletion constructs, antisense constructs, or various combinations of the foregoing. Figures 5A-5C represent several first sets of DNA sequences that are capable of expressing sense antisense or co-deletion constructs in accordance with the present invention, the non-coding sequences that are described in the following Tables 1 and 2. The non-coding sequences can be single sequences, combinations of sequences (for example, the 5'UTR linked to the 3'UTR), or any combination of the above. To express a sense co-deleted construct, all non-coding sequences are sense sequences, and to express an antisense construct, all non-coding sequences are antisense sequences. Figure 5D depicts a first set of DNA sequences that are capable of expressing sense and antisense constructs in accordance with the present invention. Figures 6A-6C represent several first sets of DNA sequences that are capable of expressing dsRNA constructs according to the present invention, the non-coding sequences that are described in the following Tables 1 and 2. The first set of DNA sequences depicted in Figures 6A-6C comprise pairs of related sense and antisense sequences, arranged such that, for example, the RNA expressed by the first sense sequence is capable of forming a double-stranded RNA with the antisense RNA expressed by the first
antisense sequence. For example, referring to Figure 6A and Illustrative Combination No. 1 (from Table 1), the first set of DNA sequences comprises a sense FAD2-1 sequence, a sense FAD3-1 sequence, an antisense and FAD2-1 sequence. an antisense FAD3-1 sequence. Both antisense sequences correspond to the sense sequences so that the expression products of the first set of DNA sequences are capable of forming a double-stranded RNA with one another. The sense sequences can be separated from the antisense sequences by a spacer sequence, preferably one that promotes the formation of a dsRNA molecule. Examples of such spacer sequences include those outlined in Wesley et al., Supra, and Hamilton et al., Plant J., 75: 737-746 (1988). The promoter is any functional promoter in a plant, or any plant promoter. Non-limiting examples of suitable promoters are described in part D of the detailed description. The first set of DNA sequences is inserted into an expression construct in sense or anti-sense orientation using a variety of DNA manipulation techniques. If convenient restriction sites are present in the DNA sequences, are inserted into the expression construct by digestion with restriction endonucleases and ligation in the construct that has been digested at one or more of the available cloning sites. If convenient restriction sites are not available in the DNA sequences, the construct DNA or sequences of
DNA are modified in a variety of ways to facilitate the DNA sequences in the construct. Examples of methods for modifying the DNA are included by PCR, synthetic linker or adapter ligation, site-directed mutagenesis in vitro, filling or retro-cutting of the pendant 5 'or 3' ends and the like. These and other DNA manipulation methods are well known to those of ordinary skill in the art. pMON97552 contains a 7Sa 'soybean promoter operably linked to an intron 1 FAD2-1 A of soybean seed (SEQ ID NO: 1), which is reduced by 140 contiguous nucleotides of the 3' end, operably linked to 42 contiguous nucleotides from a FATB-1 to 5'UTR, followed by a CTP coding region FATB-1 a, operably linked to 70 nucleotides of intron 4 FAD3-1 A operably linked to a CTP coding region FATB-1 a in the anti-orientation - felt followed by 42 contiguous nucleotides of a FATB-1 at 5'UTR in the antisense orientation, followed by a soybean FAD2-1 A intron 1 (SEQ ID NO: 1), which is reduced by 140 contiguous nucleotides of the 3 'end and in the antisense orientation, operably linked to a 3' H6 polyadenylation segment with a CP4 EPSPS gene operably linked to an EFMV promoter and an E9 3 'end sequence.

The first set of DNA sequences depicted in Figures 7-9 comprise pairs of related sense and antisense sequences, arranged as, for example, the RNA expressed by the first sense sequence is capable of forming a double-stranded RNA with the RNA antisense expressed by the first antisense sequence. The sense sequences may be adjacent to the antisense sequences, or separated from the antisense sequences by a spacer sequence, as shown in Figure 9.

EXAMPLE 4 Plant transformation and analysis
The constructs of Examples 2 and 3 are stably introduced into soybeans (for example, Asgrow A4922 or Asgrow A3244 or Asgrow A3525) by methods described at the beginning, including the methods of McCabe et al., Bio / Technology, 6: 923-926 (1988), or transformation mediated by Agrobacterium. Transformed soybean plants are identified by selection in medium containing glyphosate. The fatty acid compositions are analyzed from the seed of soy lines transformed with the constructs using gas chromatography. In addition, any of the constructs may contain other sequences of interest, as well as different combinations of promoters.
For some applications, modified fatty acid compositions are detected in seed development, while in other cases, such as for oil profile analysis, detection of fatty acid modifications that occur subsequently in the FAS path, or for detection of minor modifications to the fatty acid composition, analysis of fatty acid or mature seed oil is preferred. In addition, analysis of oil and / or fatty acid content of individual seeds may be desirable, especially in the detection of oil modification in the segregation of seed populations Ri. As used herein, the R0 generation indicates the plant emergence of the transformation / regeneration protocols described herein, the R1 generation indicates the growth of the seeds in the transgenic R0 plant itself. The R1 plants develop from the R1 seeds. The fatty acid compositions are determined for the seed of soybean lines transformed with the constructs of example 3. From one to ten seeds of each of the transgenic soybean and control soybean lines are ground individually using a tissue homogenizer (Pro Scientific) for the extraction of oil. The oil from the crushed soybean is extracted overnight in 1.5 ml of heptane containing triheptadecanoin (0.50 mg / ml). Aliquots of 200 μ? of the extracted oil are derived to methyl esters with the addition of 500 μ? of sodium methoxide in absolute methanol. The derivatization reaction is allowed to progress for 20 minutes at 50 ° C. The reaction is interrupted by the addition
Simultaneous 500 μ? 10% (w / v) of sodium chloride and heptane 400 μ ?. The resulting fatty acid methyl esters extracted in hexane are resolved by gas chromatography (GC) in a GC 6890 Hewlett Packard (Palo Alto, CA). The GC is equipped with a Supelcowax 250 column (30 m, 0.25 mm id, 0.25 microns film thickness) (Supelco, Bellefonte, PA). Column temperature is 175 ° C at the injection and the programmed temperature from 175 ° C to 245 ° C to 175 ° C to 40 ° C / min. The temperatures of the injector and detector are 250 ° C and 270 ° Cm, respectively.
EXAMPLE 5 Synthetic fuel oil with improved biodiesel properties
A synthesized fuel oil fatty acid composition is prepared having the following mixtures of fatty acid methyl esters: 73.3% oleic acid, 21.4% linoleic acid, 2.2% palmitic acid, 2.1% linolenic acid and 1.0 % stearic acid (all by weight). The purified fatty acid methyl esters are obtained from Nu-Chek prep., Inc., Elysian, MN, USA. The cetane number and the ignition delay of this composition is determined by the Southwest research Institute using an Ignition Quality Analyzer ("IQT") 613 (Southwest Research Institute, San Antonio, Texas, USA). An IQT consists of a constant volume combustion chamber that is electrically heated, an injection system
fuel, and a computer that is used to control the experiment, recording the data and providing interpretation of the data. The fuel injection system includes a fuel injection nozzle that forms an entrance to the combustion chamber. A needle enhancement sensor in the fuel injection nozzle detects the fuel flow in the combustion chamber. A pressure transducer attached to the combustion chamber measures the cylinder pressure, the pressure inside the combustion chamber. The basic concept of an IQT is measured from the time of the start of fuel injection in the combustion chamber to the start of combustion. The thermodynamic conditions in the combustion chamber are precisely controlled to provide the measurement consisting of the ignition delay time. For a cetane number and ignition delay test, the test fuel is filtered using a 5-micron filter. The fuel reservoir, injection line, and nozzle are purged with pressurized nitrogen. The fuel reservoir then re-cleans with a lint-free flannel. A portion of the test fuel is used to purge the fuel reservoir, injection line, and nozzle. The reservoir is filled with the test fuel and all the air is poured out of the system. The reservoir is pressurized to 3,402 atm. The method basically consists of injecting a precisely metered quantity of the test fuel into the combustion chamber at high pressure, which is charged with air at the desired pressure and desired temperature. The measurement consists of determining the
time from the start of the injection to the start of combustion, sometimes referred to as the ignition delay time. This determination is based on the measured needle enhancement and combustion chamber pressures. The normal cetane classification procedure requires the adjustment of skin temperature to 567.5 ° C and the air pressure to 2.1 MPa. A fuel with a known injection delay is run in the IQT combustion pump at the start of the day to ensure that the unit operates within normal parameters. The synthetic test then runs. The known fuel is run again to verify that the system has not changed. Once the fuel reservoir is reconnected to the fuel injection pump, the test procedure starts in the PC controller. The computer controls the entire procedure, including air loading, fuel injection, and exhaust events. 32 repeated combustion events are taken. The ignition delay is the time from the start of the injection.
It is determined from loyal needle enhancement and cylinder pressure data. The increase of injection needle signals starting from the injection. The cylinder pressure drops slightly due to the cooling effect of the vaporization of the fuel. The start of combustion is defined as the recovery time of the cylinder pressure - increases due to combustion at pressure is just before the fuel injection. The measured ignition delay times are then used to determine the cetane number based on a calibration curve
which is incorporated into the data acquisition and reduction software. The calibration cu which consists of cetane number as a function of the ignition delay time, is generated using mixtures of the primary reference fuels and NEG verification fuels. In the case of test fuels that are liquid at ambient conditions, the calibration cu are verified on a daily basis using at least one known cetane number fuel check (Ryan, "Correlation of Physical and Chemical Ignition Delay to Cetane Number ", SAE Paper 852103 (1985); Ryan," Diesel Fuel Ignition Quality as Determined in a Constant Volume Combustion Bomb ", SAE Paper 870586 (1986); Ryan, "Development of a Portable Fuel Cetane Quality Monitor," Belvoir Fuels and Lubricants Research Facility Report No. 277, May (1992); Ryan, "Engine and Constant Volume Bomb Studies of Diesel Ignition and Combustion", SAE Paper 881616 (1988); and Allard et al., "Diesel Fuel Ignition Quality as Determined in the Ignition Quality Tester (" IQT ")", SAE Paper 961 182 (1996)). As shown in Table 3, the synthesized oily composition exhibits cetane numbers and ignition delays which are suitable for use, for example, without limitation, as a biodiesel oil.
TABLE 3
1 The fuel called "High Check" is a calibration fuel. It can have a cetane number of 49.3 ± 0.5. The unit is verified with the calibration before and after the running of the synthetic test fuel. The fog point density (ASTM D-4052) (ASTM D-2500), pour point (ASTM D-97), and cold filter plugging point (IP 309 / ASTM D-6371) are determined for the synthesis of oil using ASTM D protocols. ASTM D protocols are obtained from ASTM, 100 Barr Harbor Drive, West Conshohocken, PA, USA. The results of these tests are set forth in Table 4. As shown in Table 4, the synthesized oil composition exhibits numbers that are suitable for use as, for example, without limitation as a biodiesel oil.
TABLE 4
Nitric oxide emission levels are estimated by evaluating the levels of unsaturation of a biologically based fuel by measuring the fuel density and directly calculating the estimated emission levels, or by measuring directly. There are also standard protocols available for levels measured directly from nitric oxide emissions. The synthesized oil is estimated to have lower nitric oxide emission levels than fatty acid methylated fatty acid esters of conventional soybean oil based on an evaluation of the overall level of instauration in the synthesized oil. Oils that contain large numbers of double bonds, that is, have a higher degree of unsaturation, tend to produce higher nitric oxide emissions. The oil has a total of 123 double bonds, as compared to the total of 153 double bonds of conventional soybean oil, as shown in table 5.

As reported by the National Renewable Energy Laboratory,
Contract No. ACG-8-17106-02 Final report, The composition effect of
biodiesel in emissions of engines of the series A DDC Series 60 Motor a
Diesel, (June 2000), nitric acid emissions of biodiesel compositions
are prededucen by the formula and - 46.959x - 36.388 where and are the emissions
of oxide in grams / hours horsepower-brake; and x is the density of
biodiesel The formula is based on regression analysis of emission data
of nitric acid in a test involving 16 biodiesel fuels. The
test makes use of a calibration 1991, serial production model 60
Detroit Diesel Corporation engine.
The density of the synthesized oil is determined by the Southwest
Research Institute using the method ASTM D4052. The result shown in
Table 4 is used in the above equation to predict an emission value
of nitric oxide of 4.89 g / bhp-h. This result is compared to a control soybean product. The National Renewable Energy Laboratory report provides the density and emissions of nitric oxide from a biodiesel based on soybeans (IGT methyl ester). The density of the control biodiesel is 0.8877 g / mL, it provides a calculated nitric oxide emission of 5.30 g / bhp-h. This calculated emission value is similar to the experimental value for nitric oxide emission of 5.32 g / bhp-h. The synthesized oil composition exhibits improved numbers compared to the control and is suitable for use, for example, without limitation, as a biodiesel oil.
EXAMPLE 6 Optimal fatty acid composition for healthy serum lipid levels
The cholesterol lowering properties of plant compositions are determined to identify fatty acid compositions that have a more favorable effect on serum lipid levels than conventional soybean oil (i.e., lower LDL-cholesterol and higher HDL-cholesterol). Published equations based on 27 clinical trials (Mensink, RP and Katan, MB Arteriosclerosis and Thrombosis, 12:91 1-919 (1992)) are used to compare the effects on serum lipid levels in human new seed compositions oleaginous
with that of normal soybean oil. Table 6 below shows the results of the change in serum lipid levels are 30% of the energy of the carbohydrate diet is replaced by lipids. The results show that soybean oil already has favorable effects on serum lipids when it replaces carbohydrates in the diet. Improvements in this composition are possible by decreasing the levels of saturated fat and by obtaining a level of linoleic acid between 10-30% of the total fatty acids, preferably around 15-25% of the total fatty acids. When the proportion of linoleic acid is less than 10% of the total fatty acids, the new composition increases the LDL-cholesterol compared to the control soybean oil, even when the saturated fat content is decreased to 5% of the total fatty acids. When the proportion of linoleic acid is increased, the ability of the composition to increase serum HDL levels is reduced. Therefore, the preferred linoleic acid is determined to be about 15-25% of the total fatty acids.

The mRNA portion of pMON68536 is then cloned directionally into pMON68529 to create pMON68537 (7S alpha promoter 'operably linked to the intron double stranded RNA formation construct # 1 FAD2-1A sense, FAD3- 1A 3'UTR sense of soybean seed, FATB- 1 3'UTR sense of soybean seed, intron # 5 FAD3-1A of soybean that can be spliced, FATB- 1 3'UTR anti-sense of soybean seed, FAD3- 1A 3'UTR anti-sense of soybean seed, intron # 1 FAD2- 1A anti-sense of soybean seed and terminator TML3 'and promoter FAD2 of soybean that triggers delta 9 desaturase).
Step 15 pMON68537 is then digested with SanDI and Ascl and pMON70683 (Napin drive KaslV) is digested with Ascl and Rsrll. The Napin / KaslV fragment is cloned directionally in pMON68537 to create pMON68539 (7S alpha promoter 'operably linked to the intron double stranded RNA formation construct # 1 FAD2- 1A sense, FAD3- 1A 3'UTR seed sense of soybean, FATB- 1 3'UTR sense of soybean seed, intron # 5 FAD3-1A of soybean that can be spliced, FA TB- 1 3'UTR anti-sense of soybean seed, FAD3- 1A 3'UTR of anti-sense soybean seed, intron # 1 FAD2-1A anti-sense and a TML3 'terminator, soybean FAD2 promoter that drives the delta 9 desaturase and the promoter
Napin activating KaslV.
EXAMPLE 9
This example illustrates the plant transformation to produce soy plants with suppressed genes. A transformation vector pMON68537 as prepared in Example 7 is used to introduce an intron double-stranded RNA / 3 'UTR formation construct into the soybean seed to suppress the? 12 desaturase,? 15 desaturase, and FATB genes. Vector pMON68537 also contains the delta-9 desaturase (FAB2) and the CP4 genes. The vector is stably introduced into soybeans (variety Asgrow A4922) via strain Agrobacterium tumefaciens ABI (Martinell, U.S. Patent No. 6,384,301). The selectable CP4 marker allows transformed soybean plants to be identified by selection in medium containing glyphosate herbicide. The fatty acid compositions are analyzed from the seed of soy lines transformed with the intron / 3 'UTR RNAid expression constructs using gas chromatography. Seed and grouped seed oil compositions Ri demonstrate that the mono- and polyunsaturated fatty acid compositions are altered in the oil of the seeds of transgenic soybean lines in comparison with those of the non-transformed soybean seed, ( see table 7). For example,
the suppression of FAD2 provides plants with increased amount of oleic acid ester compounds; the suppression of FAD3 provides plants with diminished linolenic acid ester compounds; and the deletion of FATB provides plants with reduced saturated fatty ester compounds, for example, palmitates and stearates. The selections can be made from said lines depending on the desired relative fatty acid composition. The fatty acid compositions are analyzed from the seed of soybean lines transformed with constructs using gas chromatography.

EXAMPLE 11
A construct pMON95829 as described in the 3D example is used to introduce an intron double-stranded RNA formation construct FAD2-1 into the soybean seed to suppress the Fad2 gene. The vector is stably introduced into soybeans (variety Asgrow A4922) via a strain Agrobacterium tumefaciens ABI (Martinell, U.S. Patent No. 6,384,301). The CP4 selectable marker allows the transformed soybean plants to be identified by selection in glyphosate herbicide-containing medium. Subsequently, the genomes of transformed plants are classified for concurrent tandem insertion of the first T-DNA and the second T-DNA, that is, in the assembly "right edge to right edge". The classification is carried out with Southern hybridization mapping methods. Transformed soybean plants that contain the preferred configuration in their genome are transferred to a greenhouse for seed production. For example, leaf tissue is taken from the R0 plants transformed with construct pMON95829 and Southern analysis is performed. Restriction enzyme probes and digestions are selected in order to identify events that contain a right edge-right border assembly ("RB-RB") of both T-DNA. Typically, approximately 25% of all transformants have T-DNA RB-RB properly assembled. The fatty acid compositions are analyzed from the seed of
Soybean lines transformed with a construct pMON95829 using gas chromatography as described in Example 4 to identify methyl esters of fatty acid compounds extracted from seeds. First, six Ri seeds taken from soybean plants transformed with construct pMON95829 are harvested, and the fatty acid composition of each single seed is determined. Since the Ri plants of each event are segregated for the transgenes and, therefore, produce seeds with conventional soybean seed composition, as well as modified versions. Positive seeds are grouped and averaged for each event. Pooled positive averages demonstrate that the mono- and polyunsaturated fatty acid compositions are altered in the oil of the seeds of transgenic soybean lines compared to those of the non-transformed soybean seed (see Table 9). For example, the suppression of FAD2 provides plants with increased amount of oleic acid ester compounds.

A construct pMON97552 as described in the 2D example
is used to introduce a double-stranded RNA formation construct
FAD2-1 intron in the soybean to suppress the FAD2 gene. The vector is

glyphosate herbicide. The fatty acid compositions are analyzed from the seed of soy lines transformed with a pMON97552 construct using gas chromatography as described in Example 4 to identify methyl esters of fatty acid compounds extracted from seeds. First, six Ri seeds taken from soybean plants transformed with construct pMON97552 are harvested, and the fatty acid composition of each single seed is determined. Since the plants of each event are segregated for the transgenes and, therefore, they produce seeds with conventional soybean seed composition, as well as modified versions. Positive seeds are grouped and averaged for each event. The pooled positive averages demonstrate that the mono- and polyunsaturated fatty acid compositions are altered in the oil of the seeds of transgenic soybean lines as compared to those of the non-transformed soybean seed (see Table 13).

EXAMPLE 27
TaqMan is an assay that quantifies nucleic acids via a
amplification and fluorescence measurements in real time (also called
Real-time PCR). This procedure is used to determine the degree of
deletion of target transcript in seeds of transgenic development. For
determine the absolute transcript levels of target mRNA in a
sample, a standard curve is established for each TaqMan experiment.
For this purpose, different amounts of target gene sequence
Cloned soybean, diluted in 20 ng total RNA from canola, are amplified in parallel
with samples of unknown target quantities. The accuracy of
Transcript copy number determined in this way has a margin of error of 25%. For the tempered material, total RNA is extracted using an ABI 6100 preparative nucleic acid station, and 20 ng a TaqMan sample is used. Samples are analyzed in an ABI 700 sequence detection instrument using one-step ABI Prism master-mix RT-PCR chemistry. The TaqMan count (Ct) values from the end of the TaqMan PCR reaction are plotted against the known amount of synthetic target sequence to calculate a linear regression so that the amount of target DNA FAD2-1 in an unknown sample can be determined from Ct TaqMan values at the end of each Taiman PCR reaction. The plants are transformed with pMON68540, pMON68546, or pMON80623, all of which suppress FAD2-1A (see section 3A and figure 7 for descriptions of the constructs). The total RNA is obtained from weak and transformed plants using an ABI 6100 nucleic acid preparation station. The transformed plants are homozygous third generation and have oleic acid levels greater than 50%. FAD2-1 A primers, FAD2-1 B primers, or FAD2-2A primers are added in separate TaqMan samples to the total RNA of each plant to be analyzed. Samples are analyzed in an ABI 700 sequence detection instrument using one-step ABI Prism master-mix RT-PCR chemistry. All transgenic plants suppress substantially
FAD2-1 A and FAD2-1 B transcript levels. None of the transgenic plants partially reduce FAD2-2A or FAD2-2B levels. Plant-to-plant comparisons of FAD2-1 A transcript levels in weak plants determine natural variation between plants. FAD2-1 A mRNA of developed seeds is analyzed using PCR primers, which produce the probe sequence in multiple plants. Seeds with a size of 0.2 g of fresh weight are taken from four different plants with weak R2 segregants, each plant from a different line. The R2 seed group of the same size class and four different weak segregants are analyzed. The PCR reactions are carried out in triplicate and the results are normalized in comparison to the amount of 18S RNA in each sample. Plant-to-plant biological variability in FAD2-1 A transcripts is low. Three of the four samples have a normalized TaqMan count value (Ct) of approximately 65 and one of the samples has a normalized TaqMan value (Ct) of approximately 50.
EXAMPLE 28
A contiguous 200 fragment of soybean intron 1 FAD2-1 sequence (SEQ ID NO: 1) is amplified via PCR to result in PCR products including the first 200 nucleotides of SEQ ID NO: 1, starting at the 5 end 'of SEQ ID NO: 1. PCR products are cloned directly, in sense orientation, into a vector containing the promoter
7Sa 'of soybean seed and a tml 3' termination sequence, in the manner of restriction sites designed at the 5 'ends of the PCR primers. The vector is then cut with a restriction enzyme and ligated into a vector containing the CP4 EPSPS gene regulated by the FMV promoter and an E9 3 'Rubisco termination sequence. The resulting gene expression construct is used for transformation using methods such as those described herein. The fatty acid compositions are analyzed from the seed of soy lines transformed with a construct using gas chromatography as described in Example 4 to identify methyl esters of fatty acid compounds extracted from seeds. First, six Ri seeds taken from soybean plants transformed with this construct are harvested, and the fatty acid composition of each single seed is determined. Since the Ri plants of each event are segregated for the transgenes and, therefore, produce seeds with conventional soybean seed composition, as well as modified versions. Positive seeds are grouped and averaged for each event. The pooled positive averages demonstrate that the saturated fatty acid compositions are altered in the oil of the seeds of transgenic soybean lines as compared to those of the non-transformed soybean seed.

The PCR products are cloned directly, in sense orientation, into a vector containing the soybean 7Sa 'promoter and a tml 3' terminator sequence, as a restriction site designed at the 5 'ends of the PCR primers. The vector is then cut with a restriction enzyme and ligated into a vector containing the CP4 EPSPS gene regulated by the FMV promoter and an E9 3 'Rubisco termination sequence. The resulting gene expression construct is used for transformation using methods such as those described herein. The fatty acid compositions are analyzed from the seed of soy lines transformed with this construct using gas chromatography as described in example 4 to identify methyl esters of fatty acid compounds extracted from seeds. First, six seeds R < The seeds of soybeans transformed with this construct are harvested, and the fatty acid composition of each single seed is determined. Since the R1 plants of each event are segregated for the transgenes and, therefore, produce seeds with conventional soybean seed composition, as well as modified versions. The positive seeds are
group and average for each event. The pooled positive averages demonstrate that the saturated fatty acid compositions are altered in the oil of the seeds of transgenic soybean lines as compared to those of the non-transformed soybean seed.
