Abstract

Reivindicación 1: Una molécula de ácido ribonucleico interferente (ARN) donde el ARN comprende al menos un ARNbc, donde el ARNbc es una región de ARN bicatenario que comprende hebras complementarias hibridadas, donde una de las hebras comprende una secuencia de al menos 19 nucleótidos contiguos que es al menos parcialmente complementaria a una secuencia de nucleótidos diana dentro de un gen diana de Diabrotica spp, y (i) es idéntica en al menos un 85% a un fragmento de al menos 19 nucleótidos contiguos de las SEQ ID Nº 126, 132, 141, 156, 162, 171, 186, 192 ó 201, SEQ ID Nº 274 - 276, SEQ ID Nº 280 - 282, SEQ ID Nº 301 - 318, o sus complementarias; (ii) comprende al menos un fragmento de 19 nucleótidos contiguos de las SEQ ID Nº 126, 132, 141, 156, 162, 171, 186, 192 ó 201, SEQ ID Nº 274 - 276, SEQ ID Nº 280 - 282, SEQ ID Nº 301 - 318, o sus complementarias; (iii) comprende al menos un fragmento de 19 nucleótidos contiguos de una secuencia de nucleótidos que codifica una secuencia de aminoácidos codificada por las SEQ ID Nº 126, 132, 141, 156, 162, 171, 186, 192 ó 201, SEQ ID Nº 274 - 276, SEQ ID Nº 280 - 282, SEQ ID Nº 301 - 318, o sus complementarias, o (iv) se puede hibridar en condiciones rigurosas con un polinucleótido seleccionado a partir del grupo constituido por las SEQ ID Nº 126, 132, 141, 156, 162, 171, 186, 192 ó 201, SEQ ID Nº 274 - 276, SEQ ID Nº 280 - 282, SEQ ID Nº 301 - 318, y sus complementarias, donde la molécula de ARN interferente tiene actividad insecticida sobre una plaga de coleópteros que atacan plantas. Reivindicación 19: Una composición insecticida para inhibir la expresión de un gen diana de un insecto de Diabrotica que comprende el ARN interferente de cualquiera de las reivindicaciones 1 a 8 y un portador aceptable en la agricultura. Reivindicación 25: Una planta transgénica, o parte de esta, que comprende la molécula de ARN interferente, la molécula de ácido nucleico, el constructo de ácido nucleico y/o la composición de cualquiera de las respectivas reivindicaciones anteriores, donde la planta transgénica presenta una mayor resistencia a un insecto de Diabrotica en comparación con una planta de control.

Reivindicación 70: Un método para identificar un gen diana ortólogo para utilizarlo como una estrategia de iARN con el fin de controlar una plaga de plantas, comprendiendo dicho método las etapas de: a) producir un par de cebadores que permitirán amplificar una diana seleccionada a partir del grupo que comprende o está constituido por las SEQ ID Nº 41, 42, 53 54, 71, 72, o una de sus complementarias, b) amplificar un gen diana ortólogo a partir de una muestra de ácido nucleico de la plaga de plantas, c) identificar una secuencia de un gen diana ortólogo, d) producir una molécula de ARN interferente, donde el ARN comprende al menos un ARNbc, donde el ARNbc es una región de ARN bicatenario que comprende hebras complementarias hibridadas, donde una de las hebras comprende una secuencia de al menos 19 nucleótidos contiguos que es al menos parcialmente complementaria a la secuencia de nucleótidos diana ortóloga dentro del gen diana, y e) determinar si la molécula de ARN interferente de la etapa (d) tiene actividad insecticida sobre la plaga de plantas; donde si el ARN interferente tiene, actividad insecticida respecto al gen diana de la plaga de plantas, se ha identificado un gen diana ortólogo que se puede utilizar para el control de una plaga de plantas.
