摘要： Sucrose non-fermenting1-related protein kinase 2 (SnRK2) plays a key role in plant stress signaling transduction pathways. In this study, one copy of TaSnRK2.7, a SnRK2 member of common wheat, was isolated and characterized for nucleotide diversity among 45 wheat accessions with different stress-response features. Most of the accessions were elite wheat cultivars, which had been subject to population bottlenecks and intensive selection during breeding. Nucleotide and haplotype diversity across the entire TaSnRK2.7-A region was 0.00076 and 0.590, respectively, and diversity in non-coding regions was higher than that in coding regions. Sliding-window analysis showed variable levels of nucleotide variation along the entire TaSnRK2.7-A region; the sixth intron and ninth exon represented variation-enriched regions. As predicted, neutrality tests revealed that population bottlenecks or purifying selection had acted on the TaSnRK2.7-A gene, a relatively conserved gene. Furthermore, strong linkage disequilibrium between SNP loci extends across the entire TaSnRK2.7-A region. These findings demonstrate that the TaSnRK2.7-A genomic region has evolved under extensive selection pressure during crop breeding.
