Description
Summary:Sucrose non-fermenting 1 (SNF1)-related protein kinase (SnRK) is a large family of protein kinases that play a significant role in plant stress responses. Although intensive studies have been conducted on members in some crops, little is known about the in barley. Using phylogenetic and conserved motif analyses, we discovered 46 SnRK members scattered across barley's 7 chromosomes and classified them into 3 sub-families. The gene structures of showed the divergence among three subfamilies. Gene duplication and synteny analyses on the genomes of barley and rice revealed the evolutionary features of . The promoter regions of family genes contained many ABRE, MBS and LTR elements responding to abiotic stresses, and their expression patterns varied with different plant tissues and abiotic stresses. could interact with the components of ABA signaling pathway to respond to abiotic stress. Moreover, the haplotypes of closely associated with drought tolerance were detected in a barley core collection. The current results could be helpful for further exploration of the genes responding to abiotic stress tolerance in barley.
