MYB转录因子家族是植物中最大的转录因子家族之一，在植物体内的多种生理生化反应中起着关键性作用，其中一项重要功能就是对非生物逆境的应答。这类转录因子通过调控生长发育，影响代谢产物的合成和影响激素信号等多方面参与非生物逆境的应答。介绍了MYB转录因子的结构特点和分类上的新发现，并综述了近几年MYB转录因子家族在植物响应干旱、高温、低温和高盐等非生物胁迫方面的研究进展。

MYB transcription factor family constitutes one of the richest transcription factor families in plant , and plays crucial roles in various important physiological and biochemical progresses .Response to abiotic stresses is one of the important roles for MYB transcrip-tion factors.These transcription factors participate in abiotic stress response by controlling the growth and development , regulating syn-thesis of metabolites , affecting hormone signal and other aspects .This review introduced the new findings in structural characteristics and classification of the MYB transcription factors , and summarized the research progresses on the functions of this transcription factor family in plant responses to drought , high temperature , cold, high salt and other abiotic stresses in recent years .
