Genome-Wide Identification of the Cation/Proton Antiporter (<i>CPA</i>) Gene Family and Expression Pattern Analysis Under Salt Stress in Winter Rapeseed (<i>Brassica rapa</i> L.).

ABSTRACT: The CPA gene family regulates ionic balance and pH homeostasis in cells, significantly contributing to plant stress tolerance. In this study, a total of 63 BrCPA gene family members were identified in the whole genome of Brassica rapa L. (B. rapa), and the three subfamily members were BrNHX (9), BrKEA (15), and BrCHX (39), respectively. The members of the BrCPA gene family encoded 303-1259 amino acids, with molecular weights in the range of 32,860.39~139,884.73 kDa, distributed on 10 chromosomes, and contained 17 conserved motifs, BrNHX and BraKEA, and the BrCPA gene family members had the same molecular weights on 10 chromosomes and contain 17 conserved motifs. The BrNHX and BraKEA subfamilies have
