Identification and Expression Analysis of the <i>CHX</i> Gene Family in <i>Capsicum annuum</i> L.

ABSTRACT: The cation/H⁺ exchanger (CHX) gene family plays a vital role in maintaining K⁺/Na⁺ homeostasis in plants, yet its functional characterization in pepper (Capsicum annuum L.) remains largely unexplored. To elucidate the potential roles of CHX genes in stress adaptation and development in pepper, a genome-wide identification and systematic analysis of this gene family was performed. Using a combination of Hidden Markov Model (HMM) searches, phylogenetic reconstruction, conserved motif and promoter analysis, and expression profiling across tissues and under multiple stress conditions, a total of 23 CaCHX genes were identified, which are unevenly distributed across 10 chromosomes and classified into 6 phylogenetic subfamilies.
