Genome-wide analysis of the MYB gene family and its stress-responsive expression under salinity and drought in sesame.

ABSTRACT: MYB transcription factors are key regulators of plant development and stress responses. Sesame (Sesamum indicum L.), a vital oilseed crop, is notable for its tolerance to drought and salinity. In this study, we identified 148 MYB genes in the sesame genome, all of which contain characteristic MYB domains. These genes showed substantial variation in physicochemical properties, gene structure, and chromosomal location. Subcellular localization analysis showed that most MYB proteins are nuclear, but some are distributed across multiple organelles. Promoter region analysis revealed diverse cis-acting elements related to light responsiveness, hormone signaling, and stress response. Conserved motif analysis indicated both shared and subgroup-specific motif patterns, supporting functional diversi
