Genome-Wide Identification and Characterization of the Shaker-Type K⁺ Channel Genes in Prunus persica (L.) Batsch.

ABSTRACT: Shaker-type K⁺ channels are critical for plant K⁺ acquisition and translocation that play key roles during plant growth and development. However, molecular mechanisms towards K⁺ channels are extremely rare in fruit trees, especially in peach. In this study, we identified 7 putative shaker-type K⁺ channel genes from peach, which were unevenly distributed on 5 chromosomes. The peach shaker K⁺ channel proteins were classified into 5 subfamilies, I-V, and were tightly clustered with pear homologs in the phylogenetic tree. Various cis-acting regulatory elements were detected in the promoter region of the shaker-type K⁺ channel genes, including phytohormone-responsive, abiotic stress-responsive, and development regulatory e
