植物热激蛋白响应非生物胁迫研究进展

非生物胁迫对农作物正常生长具有重要影响，非生物胁迫可改变细胞蛋白质构象，使非天然蛋白质发生聚集，破坏细胞膜结构。热激蛋白（heat shock proteins，Hsps）负责蛋白质的折叠、组装、转运与降解，并能在胁迫条件下协助蛋白质复性，通过重建正常的蛋白质构象从而恢复细胞稳态，参与其他应激反应机制，在保护植物免受非生物胁迫方面起着重要作用。总结了各类 Hsps 在植物非生物胁迫响应中发挥的功能，阐述Hsps 参与其他应激反应机制并发挥一定作用，对目前 Hsps 在研究中存在的问题进行讨论和展望，为作物分子育种筛选抗逆基因提供理论依据。

Research Progress of Plant Heat Shock Protein Response to Abiotic Stress

Abiotic stress has an important effect on the normal growth of crops. The conformation of cellularproteins can be altered by abiotic stress, which causes the aggregation of non-natural protein and the destruction ofcell membrane structure. Heat shock proteins are responsible for the folding, assembly, transport and degradation ofprotein, assist the protein refolding under stress conditions and restore cell homeostasis by reconstructing normal proteinconformation. Hsps can participate in other stress response mechanisms and play an important role in protecting plantsfrom abiotic stress.The functions of various Hsps in plant abiotic stress response were summarized in this paper. Theinvolvement of Hsps in other stress response mechanisms and the role of Hsps in other stress response mechanisms weredescribed. And the problems existing in the research of Hsps were discussed and proposed, which provided a theoreticalbasis for the selection of stress-resistant genes in crop molecular breeding.
