Identification and expression profiling analysis of NBS-LRR genes involved in Fusarium oxysporum f.sp. conglutinans resistance in cabbage.

ABSTRACT: As one of the most important resistance (R) gene families in plants, the NBS-LRR genes, encoding proteins with nucleotide-binding site (NBS) and leucine-rich repeat (LRR) domains, play significant roles in resisting pathogens. The published genomic data for cabbage (Brassica oleracea L.) provide valuable data to identify and characterize the genomic organization of cabbage NBS-LRR genes. Ultimately, we identified 105 TIR (N-terminal Toll/interleukin-1 receptor)-NBS-LRR (TNL) genes and 33 CC (coiled-coil)-NBS-LRR (CNL) genes. Further research indicated that 50.7% of the 138 NBS-LRR genes exist in 27 clusters and there are large differences among the gene structures and protein characteristics. Conserved motif and phylogenetic analysis showed that the structures of TNLs and CNL
