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

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 stud...

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.

Phylogenetic analysis revealed that at least 740 NBS-LRR lineages are present in the common ancestor of S. cereale, Hordeum vulgare and Triticum urartu.
