Genome-Wide Characterization of <i>WRKY</i> Gene Family in <i>Camellia chekiangoleosa</i> Identifies Potential Regulatory Components in Pigment Biosynthesis Pathways.

ABSTRACT: The WRKY gene family is essential for controlling a variety of plant physiological functions, yet the involvement of specific WRKY members in pigment biosynthesis and accumulation in Camellia chekiangoleosa remains unexplored, particularly in anthocyanins and carotenoids, which play crucial roles in the pigmentation of C. chekiangoleosa. This study systematically identified 87 WRKY genes across 15 chromosomes in C. chekiangoleosa through bioinformatic approaches. Further structural and phylogenetic analyses of these TFs enabled their classification into six different subgroups. WRKY family expansion was shown to be mostly driven by tandem duplication. W-box elements, which can be binding sites for WRKY transcription factors, were present in
