The major domains of NBS-LRR proteins. Examples of proteins with each configuration are shown on the right. Bs4, I2, Mi, and Prf are from tomato; L6 from flax; N from tobacco; RAC1, RPP5, RPS4, RRS1, RPP8, RPP13, RPS2, RPS5, and RPM1 from Arabidopsis; Y-1 and Rx from potato; Mla from barley; RGC2 from lettuce; Bs2 from pepper. N, amino terminus; TIR, Toll/interleukin-1 receptor-like domain; CC, coiled-coil domain; X, domain without obvious CC motif; NBS, nucleotide binding site; L, linker; LRR, leucine-rich repeat domain; WRKY, zinc-finger transcription factor-related domain containing the WRKY sequence; C, carboxyl terminus.
