The present invention provides double stranded RNA compositions and transgenic plants capable of inhibiting expression of essential genes in parasitic nematodes, and methods associated therewith. Specifically, the invention relates to the use of RNA interference to inhibit expression of a target essential nematode gene, which is a nematode innexin -like, pas-1, tcp-1, snurportin-1 like, pol delta S, prs-4, rtp-1 or rpn-5 gene, and relates to the generation of plants that have increased resistance to parasitic nematodes.
