Abstract: Under environmental stress, plants would produce a series of stress responses, and the heat shock transcription factors play important roles in stress tolerance and other life activities in plants by mediating the transcription and expression of heat shock proteins or other heat-inducible genes. The basic protein domains of plant heat shock transcription factors were introduced, and the functions and mechanism of three kinds of plant heat shock transcription factors were expounded when plant subjected to extreme temperature（high temperature and low temperature）stress, drought stress, high salt stress and reactive oxygen species stress. In addition, the development and application prospects of plant heat shock transcription factors in plant breeding and enhancing plant stress resistance were discussed, which may provide theoretical reference for future study on the biological function and mechanism of heat shock transcription factors during regulating plant resistance to stress.
