摘要

The present invention provides a double stranded RNA molecule comprising an antisense strand and a sense strand, wherein the nucleotide sequence of the antisense strand is complementary to a portion of the nucleotide sequence of a Hg-rps-23 gene of a soybean cyst nematode, nucleic acid molecules encoding the RNA molecules and compositions comprising the nucleic acid molecules and RNA molecules of this invention, as well as methods of their use in enhancing resistance of a plant or plant cell to nematode infestation and infection.
