Plants face various stresses during the growth and development processes. The specific transcription factors bind to the -acting elements upstream of the stress resistance genes, specifically regulating the expression of the gene in plants and increasing the adaptability of plants to environmental stress. The transcription factor-mediated gene expression regulatory networks play an important role in plant stress response pathways. MYB (v-myb avian myeloblastosis viral oncogene homolog) transcription factor is one of the largest members of the transcription factor family in plants. It participates and has a great influence on all aspects of plant growth and development. It plays an important role in plant secondary metabolic regulation, hormone and environmental factor responses, cell differentiation, organ morphogenesis, and cell cycle regulation. This review mainly introduces the characteristics, structure, and classification of MYB transcription factors, as well as the abiotic stress resistance to drought, salt, temperature, and other functions in breeding, and provides a reference for the research and utilization of transcription factors in the future.
植物在生长发育过程中面临各种胁迫。特定的转录因子与抗逆基因上游的顺式作用元件结合，特异性地调控植物中该基因的表达，提高植物对环境胁迫的适应性。转录因子介导的基因表达调控网络在植物胁迫响应途径中发挥重要作用。MYB（v-myb禽成髓细胞瘤病毒癌基因同源物）转录因子是植物转录因子家族中最大的成员之一。它参与植物生长发育的各个方面并产生重大影响。它在植物次生代谢调控、激素和环境因子响应、细胞分化、器官形态发生以及细胞周期调控中发挥重要作用。本综述主要介绍MYB转录因子的特性、结构和分类，以及在育种中对干旱、盐、温度等非生物胁迫抗性的功能，为今后转录因子的研究和利用提供参考。
