植物热激转录因子家族的研究进展

Heat shock transcription factor family in plants: a review

摘要:

随着全球气候的不断变化，植物常遭受热胁迫、干旱胁迫、冷胁迫、盐碱胁迫等多种非生物胁迫。植物热激转录因子 (Heat shock transcription factors，HSFs) 作为植物体内广泛存在的一类转录因子，能够响应多种非生物胁迫。文中就HSFs的结构、信号调控机制以及其在主要植物拟南芥、番茄、水稻和大豆中的研究进行回顾和总结，以期为进一步阐明HSFs在逆境调控网络中的作用提供参考。

Abstract:

With the constant change of global climate, plants are often affected by multiple abiotic stresses such as heat stress, drought stress, cold stress and saline-alkali stress. Heat shock transcription factors (HSFs) are a class of transcription factors widely existing in plants to respond to a variety of abiotic stresses. In this article, we review and summarize the structure, signal regulation mechanism of HSFs and some research in plants like Arabidopsis thaliana, tomato, rice and soybean, to provide reference for further elucidating the role of HSFs in the stress regulation network.
