摘　　要：基因的时空表达受转录因子的精确调控。植物在面对不利环境因素比如高温、低温、干旱、盐碱等胁迫时其细胞生理生化会迅速地从“舒适”状态转变进入“胁迫响应”状态。这种快速响应的状态转变依赖于植物对胁迫信号的感知及传递、激素通路(脱落酸、茉莉酸等)的激发、转录因子的活化等复杂的过程;最终植物通过胁迫相关基因的表达、次生代谢转变、抗氧化物质的积累等实现胁迫条件下细胞内环境的再平衡从而获得生存。植物MYB(v-MYB avian myeloblastosis viral oncogene homolog)转录因子就是上述转变中的重要参与者。本文介绍了植物MYB转录因子的结构特征、分类,综述了近些年来MYB转录因子与非生物胁迫,以及植物激素应答过程相关的研究进展。The expression of a gene is tightly controlled by transcription factors in a spatiotemporal way.When facing adverse environmental conditions such as heat,cold,drought or salt stress,plant cells conduct a physiological change from“fitness”to“stress response”immediately.This fast response relies on complex strategies including the perception and transduction of the stress signal,initiating hormone signaling(abscisic acid,jasmonic acid etc.),transcription factor activation etc.These processes turn out the expression of stress related genes,secondary metabolic transformation,antioxidants accumulation etc.All these efforts confer plants to strive a rebalance of cell homeostasis under stress,and so enable plants to survive.Plant MYB(v-MYB avian myeloblastosis viral oncogene homolog)transcription factors are important participants in these procedures.This manuscript described the plant MYB transcription factor s structure features,classification,and mainly focused on the recent advances in the researches about MYB’s functions in response to abiotic stress and plant hormones.
