Genome-Wide Identification and Expression Analysis of the PEPC Gene Family in <i>Zanthoxylum armatum</i> Reveals Potential Roles in Environmental Adaptation.

ABSTRACT: Phosphoenolpyruvate carboxylase (PEPC) is a crucial enzyme in plant photosynthesis and stress responses, yet its gene family remained uncharacterized in Zanthoxylum armatum. This study presents the first genome-wide identification and comprehensive analysis of the PEPC gene family in Z. armatum. A total of 12 ZaPEPC genes were identified and classified into plant-type (PTPC) and bacterial-type (BTPC) subfamilies based on phylogenetic analysis. These genes exhibited conserved protein domains but distinct gene structures, with evidence of gene duplication events contributing to family expansion. Promoter analysis revealed an abundance of stress- and hormone-responsive cis-elements, particularly those related to light, abscisic acid (ABA), and methyl jasmonate (MeJ
