摘　　要：MYC2(Myelocytomatosis proteins 2)是一类b HLH家族转录因子,是JA信号途径中的主要调控因子。MYC2通过转录调控下游目标基因的转录和表达,参与植物逆境防御、生长发育及次生代谢等进程。MYC3/4作为JA信号的次级调控因子可与MYC2协同作用。目前对MYC2的功能研究较为深入和广泛。本文综述了MYC2的结构特征及其在植物激素信号传导、逆境防御、生长发育和次生代谢中的调控机制,为进一步深入探讨MYC2的分子功能提供理论基础。MYC2(Myelocytomatosis proteins 2),a transcription factor in the bHLH family,is the main regulator in JA signaling.MYC2 participates in life activities such as stress defense,growth and development,and secondary metabolism by regulating the transcription and expression of downstream target genes.As a secondary regulator of JA signaling,MYC3/4 can cooperate with MYC2.At present,the functional mechanism of MYC2 has been studied deeply and extensively.This paper summarizes the structural characteristics of MYC2 and its regulatory mechanisms in plant hormone signaling,stress defense,growth and development,and secondary metabolism,providing a theoretical basis for further investigation molecular functions of MYC2.
