MYBs constitute one of the largest transcription factor families, with more than 200 genes identified in the Arabidopsis thaliana genome alone. MYBs are key regulators of developmental plasticity, cell differentiation, and plant adaptation to ever-changing environments owing to their large number, diverse expression patterns across different tissues and environmental conditions, and broad functional diversity. This review provides an updated overview of MYB functions in plants, with a focus on their roles in epidermal differentiation and the formation of extracellular protective barriers. MYB–employed regulatory strategies ensuring robust, precise, flexible, and spatially restricted gene expression are also highlighted.
