The invention provides expression vectors comprising root-specific promoters in operative association with polynucleotides that are down-regulated in syncytia of nematode-infected plants, for use in methods of producing transgenic plants with increased resistance to nematode infestation. The invention also provides nematode-resistant transgenic plants and seeds comprising such expression vectors.
