Genome-wide identification and expression analysis of <i>CCoAOMT</i> genes in <i>Capsicum annuum</i> L. under drought stress.

ABSTRACT:

Introduction

Lignin biosynthesis is critical for plant structural integrity and stress response, with Caffeoyl-CoA O-methyltransferase (CCoAOMT) playing a pivotal role. This study investigates the CaCCoAOMT gene family in pepper (Capsicum annuum) based on the Zunla-1 genome to elucidate their molecular characteristics and drought stress responses.

Methods

Eleven CaCCoAOMT genes (CaCCoAOMT1-CaCCoAOMT11) were identified and analyzed for physicochemical properties, phylogenetic relationships, gene structure, conserved motifs, and promoter elements. Gene expression patterns were validated using qRT-PCR under drought stress, and subcellular localization of CaCCoAOMT1 and CaCCoAOMT2 was determined in tobacco leaves.
