  1. aBased on the presence or absence of CC, TIR, NBS and LRR domains, the NBS genes were classified into CC-NBS-LRR, TIR-NBS-LRR and four Truncated NBS-LRR types. bTruncated NBS-LRR means NBS genes lacking N-terminal domain (TIR or CC) or C-terminal domain (LRR), and classified into NBS-LRR, TIR-NBS, CC-NBS, NBS
