Provided are double stranded RNA compositions and transgenic plants capable of inhibiting expression of plants genes, and methods associated therewith. Specifically, the use of RNA interference to inhibit expression of a plant sterol C-14 reductase polynucleotide and the generation of plants that have increased resistance to parasitic nematodes are provided. L'invention concerne des compositions d'ARN double brin et des plantes transgéniques capables d'inhiber l'expression de gènes végétaux, et les procédés qui y sont associés. En particulier, l'invention concerne l'utilisation de l'interférence d'ARN pour inhiber l'expression d'un polynucléotide de réductase en C-14 de stérol végétal et la génération de plantes qui ont une résistance accrue aux nématodes parasites.
