热激因子对增强植物耐热性的研究进展

Advances in Research of Enhancing Plant Heat Resistance by Heat Shock Factors

热激因子作为生物体在热胁迫和其他胁迫中基因转录激活信号转导通路中的重要成员,能直接启动下游热激蛋白基因的表达,维持细胞内蛋白质的稳态状态。介绍了植物热激因子的种类、结构特点、调控机制及其在不同作物中对高温和其他胁迫下的重要作用。

As an important member in the gene transcriptional activation signal transduction pathways of the organism under the thermal stress and the other stress, the heat shock factors can directly activate the expression of the downstream heat shock protein gene and maintain steady state of intracellular protein. The types, structure and regulation mechanism of the plant heat shock factor as well as their functions in high temperature and other stress in various crops are presented.
