果树高温逆境应答反应的研究进展

Research progress on high temperature stress response in fruit trees

综述了高温逆境下果树的应答反应,具体表现在:高温逆境伤害果树叶片组织结构;影响果树的光合效率、细胞膜功能、抗氧化系统平衡和可溶性糖含量等生理生化变化;激素、信号物质和磷酸化信号通路也会应答高温逆境;与高温逆境相关的基因和蛋白在高温逆境下应答表达。此外,高温逆境与光胁迫、盐胁迫、氧化胁迫和干旱胁迫也存在密切关系。

This article summarized the response of fruit trees to high temperature stress,such as;high temperature stress damaged leaf tissue structure of fruit tree and affected the physiological and biochemical changes of photosynthetic efficiency,cell membrane function,antioxidant system balance and soluble sugar content of fruit trees;Hormone,signal material and phosphorylation signal pathway also responded to high temperature stress;Genes and proteins associated with high temperature stress response expressed in high temperature stress.In addition,there was a close relationship among light stress,salt stress,oxidative stress,drought stress and high temperature stress.
