摘要:

植物在遭遇逆境时会产生一系列应激反应,热激转录因子(Heat stress transcription factors,Hsfs)作为重要调控元件参与植物防御过程。相比动物,固着生长的植物其Hsfs家族成员在数量、结构及调控机制上表现出更丰富的多样性。Hsfs在多种逆境中发挥作用,参与不同转录调节途径,形成复杂的调控网络。综述介绍了植物Hsfs的主要蛋白质结构、在调控植物逆境响应方面发挥的重要作用及其转录调控机制等研究进展,以期为深入研究Hsfs调控逆境响应的生物学功能提供参考。

Abstract:

Plants produce a series of defense systems under abiotic and biotic stresses,where heat stress transcription factors(Hsfs)are involved as important regulators. Because plants are sessile organisms,plants Hsfs show high diversity in the gene family members,protein structures,and regulatory mechanisms,when compared with the animal Hsfs. Hsfs play important roles in multiple stresses and they are involved in different transcriptional regulatory pathways,which eventually result in forming a complex regulatory network. This review summarized the main protein structures,stresses responses and regulations mechanism of plant Hsfs during stresses. This review summarized the main protein structures,stresses responses and regulation mechanism of plant Hsfs during stresses,which may provide insight for future study on the biological function of Hsfs during stress in plants.

Key words: heat stress transcription factors, plant, stress, regulation
