摘要

Chickpea, a globally important legume crop, has been extensively studied for its MYB transcription factors (TFs), which play crucial roles in plant growth, development, and stress response. In this study, we conducted a genome-wide analysis of 113 CaMYB-TFs, examining chemical properties, conserved domains, phylogenetic relationships, gene structures, chromosomal distribution, and synteny with Arabidopsis thaliana and Medicago truncatula. The CaMYB-TFs displayed considerable diversity in sequence characteristics and were unevenly distributed across the chickpea genome, with several genes remaining unplaced. The CaMYB-TFs displayed considerable diversity in sequence characteristics and were unevenly distributed across the chickpea genome, with several genes remaining unplaced. Conserved domain analysis revealed six major MYB-related domains, and phylogenetic clustering grouped the genes into nine distinct clades. Synteny and protein–protein interaction analyses indicated evolutionary conservation and functional relevance under abiotic stress. This comprehensive study enhances our understanding of the MYB gene family in chickpea and provides a solid foundation for future functional and evolutionary research.
