植物MYB转录因子的特点是含有一个结构保守的MYB结构域，在植物发育和代谢的调控中发挥着广泛的作用。单个MYB结构域蛋白参与染色体结构的转录调控和维持。具有两个MYB结构域的R2R3 MYB蛋白组成了一个大家族。它们在植物中的作用是调节次生代谢和控制细胞形态发生。具有三个MYB结构域的R1R2R3 MYB蛋白仅包含少数成员，与c MYB蛋白具有高度同源性。它们的作用应该是细胞周期的调节者。
Plant MYB transcription factors are characterized by containing a structurally conserved MYB domain and play ubiquitous roles in the regulation of plant development and metabolism. The single MYB domain proteins are involved in transcriptional regulation and maintenance of the chromosome structure. The R2R3 MYB proteins with two MYB domains comprise a large family. Their functions in plants are to regulate the secondary metabolism and control cellular morphogenesis. The R1R2R3 MYB proteins with three MYB domains contain only a few members and share high homology with c MYB protein. Their roles are supposed to be the regulators of the cell cycle.
