Genome-wide Identification and Evolutionary Analysis of NBS-LRR Genes From Secale cereale.

ABSTRACT: Secale cereale is an important crop in the Triticeae tribe of the Poaceae family, and it has unique agronomic characteristics and genome properties. It possesses resistance to many diseases and serves as an important resource for the breeding of other Triticeae crops. We performed a genome-wide study on S. cereale to identify the largest group of plant disease resistance genes (R genes), the nucleotide-binding site-leucine-rich repeat receptor (NBS-LRR) genes. In its genome, 582 NBS-LRR genes were identified, including one from the RNL subclass and 581 from the CNL subclass. The NBS-LRR gene number in the S. cereale genome is greater than that in barley and the diploid wheat genomes. S. cereale chromosome 4 contains the largest number of NBS-LRR genes amo
