Schematic representation of plant NBS-LRR R gene structure. (A) Characteristic plant R gene domains. (B) Conserved motifs within the NBS domain. The solid arrow indicates the position and direction of the designed degenerate forward and reverse primers (P-loop and GLPL conserved motifs, respectively). The degenerate primer sequences are shown in Additional file 5.
