Identification and characterization of novel NBS-LRR resistance gene analogues from the pea
Pea (Pisum sativum) is one of the most cultivated legumes in the world, and its yield and seed quality are affected by a variety of pathogens. In plants, NBS-LRR (nucleotide binding site-leucine-rich repeat) is the main class of disease resistance genes. Using degenerate primers deduced from conserved motifs in the NBS domain of known resistance genes, we identified 10 NBS sequences in three varieties of P. sativum.
