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
