Genome-wide identification of PSKR genes in wheat and differential expression under abiotic stress conditions.

ABSTRACT: Phytosulfokine (PSK) is an important plant growth factor regulating plant stress response, PSKR gene family plays an important role in the PSK signaling pathway, but there are few reports in wheat (Triticum aestivum L.). In this study, 149 TaPSKR genes were identified by using hidden Markov models (HMMs) and sequence homology, and their evolutionary relationship, structural characteristics and stress regulation mechanism were systematically analyzed. Our results indicated that genes were unevenly distributed across 21 chromosomes of the wheat genome. Phylogenetic tree and conserved motif analysis revealed that the gene motifs, domains, and structures were relatively conserved, and 75.2% of TaPSKR genes clustered in one clade with monocotyledons.
