Abstract:

Transcription factors are important regulatory proteins that regulate gene expression. Transcription factors and the related cis-acting elements of promoters which bind to them both play the role of molecular switches in gene expression, therefore it is particularly important to explore the interaction of transcription factors with promoters. In order to study the regulation mechanism of transcription factors on downstream target genes when plants are subjected to stress, this paper summarized the main transcription factor families involved in stress, the identification of transcriptional activation activity of transcription factors, the interaction analysis technologies between transcription factors and promoters and their applications in plants’ response to stress, which could provide references for the comprehensive and in-depth study of the gene expression regulation mechanism of plants in response to stress.

Key words: transcription factor, promoter, ChIP, DNase I footprinting, EMSA, Y1H, stresses
