摘要/Abstract

摘要： 热激蛋白(heat shock protein，HSP)是一种普遍具有抗逆作用的保护蛋白，主要通过分子伴侣形式与其他蛋白结合来保护蛋白稳态及修复变性蛋白从而维持植物内环境的稳定，在植物生长发育及逆境调控过程中发挥重要作用。植物热激蛋白分为HSP100、HSP90、HSP70、HSP60、小分子HSP 五大家族，每一家族含有多个热激蛋白。随着对HSP的不断研究，已有大量文献报道了不同物种中的热激蛋白，在此基础上通过阐述植物热激蛋白的结构、功能以及调控作用，旨在为进一步认识热激蛋白及其作用机理提供有价值的参考。

Abstract: Heat shock protein(HSP)is a kind of ubiquitous protective protein in plant.HSP mainly acts as a molecular chaperone to maintain protein in steady state and repair denatured proteins through binding with target proteins, which keep the stability of plant internal environment.Therefore, HSP plays a key role in plant development and stress-resistance process.These proteins can be classified as 5 families of HSP100, HSP90, HSP70, HSP60 and small molecular HSP, and each family consists of many different HSPs.In this review, based on the reported HSPs of varied species in the abundant literatures, we summarize the structure, function and regulatory mechanism of plant HSPs, which aims at providing reference information for understanding plant HSP and its mechanism.

Key words: heat shock protein, chaperone, heat shock factor, resistance
