摘要: 通过对现有研究的梳理和分析,综述植物应答极端温度、干旱、水淹和盐胁迫的分子机制。结合不同非生物胁迫对植物生长发育的影响,介绍植物响应逆境的信号感知方式和信号转导途径;分析基因表达调控过程中重要转录因子的调控机制以及胁迫耐受性产生期间重要次生代谢产物的作用方式。最后,从多信号网络调控机制以及农业可持续发展的角度,对未来的研究方向作了展望。

关键词: 非生物胁迫, 信号应答, 基因表达调控, 耐受性, 抗逆分子机制

Abstract: In this review, the molecular mechanisms by which plants respond to extreme temperature, drought, flooding and salt stress, through an overview of existing studies were summarized. Combining the effects of various stress on plant growth and development, the signal perception mode and signal transduction pathways were introduced. Meanwhile, the regulatory mechanisms of critical transcription factors in regulating gene expression and important secondary metabolites in coordinating stress tolerance were outlined. Finally, an outlook on future research was prospected focusing on the regulatory mechanism of mult-signaling network modules and sustainable development of agriculture.

Key words: abiotic stress, signal response, gene expression regulation, tolerance, molecular mechanisms of stress resistance
