Genome-wide identification, characterization, and evolutionary analysis of NBS-encoding resistance genes in barley.

ABSTRACT: In this study, a systematic analysis of Nucleotide-Binding Site (NBS) disease resistance (R) gene family in the barley, Hordeum vulgare L. cv. Bowman, genome was performed. Using multiple computational analyses, we could identify 96 regular NBS-encoding genes and characterize them on the bases of structural diversity, conserved protein signatures, genomic distribution, gene duplications, differential expression, selection pressure, codon usage, regulation by microRNAs and phylogenetic relationships. Depending on the presence or absence of CC and LRR domains; the identified NBS genes were assigned to four distinct groups; NBS-LRR (53.1%), CC-NBS-LRR (14.6%), NBS (26%), and CC-NBS (6.3%). NBS-associated domain analysis revealed the presence of signal peptides, zinc fingers, div
