Genome-wide analysis of the soybean CRK-family and transcriptional regulation by biotic stress signals triggering plant immunity.

ABSTRACT: Cysteine-rich receptor-like kinases (CRKs) are transmembrane proteins that exhibit ectodomains containing the domain of unknown function 26 (DUF26). The CRKs form a large subfamily of receptor-like kinases in plants, and their possible functions remain to be elucidated. Several lines of evidence suggest that CRKs play important roles in plant defense responses to environmental stress, including plant immunity. We performed a genome-wide analysis of CRK encoding genes in soybean (Glycine max). We found 91 GmCRKs distributed in 16 chromosomes, and identified several tandem and segmental duplications, which influenced the expansion of this gene family. According to our phylogenetic analysis, GmCRKs are grouped in four clades. Furthermore, 12% of the members exhibited GmCRKs with a duplicated
