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
