QTL mapping and transcriptome analysis of cowpea reveals candidate genes for root-knot nematode resistance.
Cowpea is one of the most important food and forage legumes in drier regions of the tropics and subtropics.However, cowpea yield worldwide is markedly below the known potential due to abiotic and biotic stresses, including parasitism by root-knot nematodes (Meloidogyne spp., RKN).Two resistance genes with dominant effect, Rk and Rk2, have been repo
