Abstract: Heat shock transcription factors (HSFs) are involved in the regulation of plant growth and development. Furthermore, HSFs regulate the expression of a series of genes related to various abiotic stress adaptations. HSFs usually form homotrimers to activate their transcriptional activity and function. Here, we review the basic structure, subcellular localization, transcriptional regulation, functional diversity of HSFs, and their roles in plant adaptation to abiotic stresses, such as extreme temperature, salinity, drought, strong light and oxidative stress, etc. HSFs are high-quality candidate genes for improving the resistance of higher plants to multiple stresses. Studies of HSFs have important application value. In the future, using HSFs to improve the resistance of various crops through genetic engineering would be prospects of development.

Key words: heat shock transcription factor, heat shock protein, functional diversity, abiotic stress adaptation
