Abstract

MYB transcription factors function as main regulatory hubs that integrate environmental signals with multi-hormonal pathways to synchronize plant growth, metabolism and stress responses. This review delineates the regulatory roles of MYB in the signalling pathway of salicylic acid, jasmonic acid, ethylene and abscisic acid signalling. These are responsible for regulating hormone biosynthesis and facilitating interaction between biotic and abiotic stress responses. The post-translational regulation of MYB activity by kinase cascades and the direct regulation of secondary metabolic pathways, such as the biosynthesis of phenylpropanol and lignin, by MYBs through the MYB-bHLH-WD40 (MBW) complex were investigated. MYB transcription factors located at the intersection of hormone signalling, metabolic regulation, and developmental regulation play a unique role in coordinating plant adaptation from the cellular level to the whole plant.

MYB因子：植物胁迫和激素串扰的中枢。

MYB转录因子是整合环境信号和多激素途径的主要调控枢纽，以同步植物的生长、代谢和胁迫反应。本文综述了MYB在水杨酸、茉莉酸、乙烯和脱落酸信号通路中的调控作用。它们负责调节激素的生物合成，促进生物和非生物应激反应之间的相互作用。研究了MYB通过激酶级联反应对MYB活性的翻译后调控，以及MYB通过MYB- bhlh - wd40 （MBW）复合物直接调控次级代谢途径，如苯丙醇和木质素的生物合成。MYB转录因子位于激素信号、代谢调节和发育调节的交叉点，在协调植物从细胞水平到整个植物的适应中发挥着独特的作用。
