Description
技术领域
本发明涉及生物工程技术领域,具体涉及芒果精氨酸脱羧酶基因MiADC的克隆方法。
背景技术
芒果(Mangifera indica L.)属于漆树科,芒果属,是著名的热带水果,有“热带果王”之称,与香蕉、柑桔、苹果及葡萄并列成为世界五大水果。在生产过程中,培育品种优良、抗病性强、耐贮性好和矮化的芒果品种是研究者的重点指标。
精氨酸是植物体内N/C比最高的氨基酸之一,它可以很少的碳结合很多的氮。L-精氨酸在植物中除作为一种重要的氮素贮藏营养物供再利用外,还是生成多胺(PA)和一氧化氮(NO)等的前体物质,而PA和NO都是植物中重要的信使分子,参与包括生长发育、抗逆性等在内的几乎所有的生理生化过程。精氨酸脱羧酶(ADC)、精氨酸酶(ODC)和一氧化氮合酶(NOS)是L-精氨酸分解代谢的关键酶,精氨酸可经ADC或ODC途径形成PA,也可经NOS途径形成NO,3个酶活性的相对强弱,决定了精氨酸的代谢方向。根系在越冬期间会积累丰富的精氨酸;精氨酸代谢对于植物感知和适应环境变化有重要意义。
因ADC基因在非生物胁迫条件下发挥重要作用,在拟南芥(Waston et al.,1996;Urano et al.,2003)、大豆(Nam et al.,1997)、水稻(Chattopadhyay et al.,1997)、葡萄(Primikirios et al.,1999)等作物中已获得其全长cDNA序列。虽然有较多的研究证实了ADC基因被克隆,但是在芒果中尚未见该基因克隆及序列分析的报道。
发明内容

4)以步骤2)中获得的3'/5'RACE ready cDNA为模板,以步骤3)获得的保守区序列设计特异性引物扩增MiADC基因,并进行克隆测序。
其中,步骤1)中采集芒果幼嫩叶片,通过改良CTAB法抽提芒果总RNA。
步骤2)中采用第一链cDNA合成试剂盒(RevertAid First Strand cDNASynthesis Kit)和cDNA末端快速扩增试剂盒(SMARTer RACE cDNA Amplification Kit)。
步骤3)中利用NCBI搜索不同物种中MiADC基因编码的氨基酸序列,进行多序列比对后,在保守区域设计简并引物,引物信息为:
ADC-sense:5'-CACCCTGCCCCACcargarathga-3'
ADC-antisense:5'-GCCGGAGGTGGAGccraartgncc-3'。
5、根据权利要求1所述的芒果精氨酸脱羧酶MiADC基因的克隆及序列分析方法,其特征在于:步骤4)中获得MiADC基因的保守区序列后,采用primer premier 5.0软件设计MiADC基因的特异引物,并通过RACE法进行MiADC基因克隆;
引物信息为:
ADCGsp1-1:5'-GAGCAAAACTGAGAACTAAACATTCGGGACA-3'
ADCGsp1-2:5'-CGTGTGGTGAGGAAACTTGAACAGGCT-3'
ADCGsp2-1:5'-GCCAGCCTGTTCAAGTTTCCTCACCA-3'。
在完成MiADC基因的克隆后,可以采用生物信息学的手段进行序列分析,即采用生物软件进行了MiADC基因序列的分析。
本发明的有益效果:本发明是以芒果为试验材料,通过设计简并引物获得该基因的保守区序列后,再设计特异性引物,利用RACE技术克隆获得芒果精氨酸脱羧酶基因MiADC的全长cDNA序列,为芒果在非生物胁迫条件下进行分子育种提供基因资源,为生态农业的发展提供理论支撑。
