植物耐热机理研究进展

Advances in heat tolerance mechanisms of plants

气候因素导致的热胁迫严重影响农作物的产量和质量,引起了广泛关注。植物通过积累不同的代谢产物,并激活一系列信号途径来应对热胁迫,这些变化凸显了植物热胁迫响应生理和分子机制的复杂性。本文详细综述了生物膜、活性氧解毒机制、热激蛋白和各类保护剂在植物耐热性形成中的作用,并对未来如何深入研究植物热胁迫响应及耐热性机制机理提出展望,以期为植物耐热性育种提供指导。

Heat stress caused by climate factors seriously affects crop yield and quality,which has attracted wide attention.In response to heat stress,different metabolites were accumulated in plants and a series of signaling pathways were activated.These changes highlighted the complexity of physiological and molecular mechanisms of plant response to heat stress.In this paper,the role of biomembrane,active oxygen detoxification mechanism,heat shock protein and various protectants in the formation of plant heat tolerance was reviewed in detail,and the further study for the response of plant heat stress and the mechanism of heat tolerance was prospected in order to provide guidance for plant heat tolerance breeding.
