The present invention relates to a method for creating a plant having resistance to RNA viruses, comprising incorporating a DNA sequence encoding an animal cell-derived (2'-5') oligoadenylate synthetase and a DNA sequence encoding an animal cell-derived ribonuclease L into a chromosome(s) of the plant and expressing the DNA sequences, as well as plants created by the above method. The present invention is widely applicable to the breeding of virus resistant plant varieties.
L'invention porte sur un procédé d'obtention de plantes résistant à un virus à ARN consistant à intégrer à un chromosome végétal une séquence d'ADN provenant de cellules animales et codant pour la synthétase de l'acide 2',5'-oligoadénylique, ainsi qu'une autre séquence d'ADN provenant de cellules animales et codant pour la ribonucléase L, puis à en assurer l'expression. L'invention porte également sur la plante ainsi obtenue. Ladite invention s'applique largement à la mise au point de variétés de plantes résistant aux virus.
