摘要:

转录因子是一类调节基因表达的重要调控蛋白,转录因子和与其结合的启动子中的相关顺式作用元件,在基因表达方面起着分子开关的作用,因此探究转录因子与启动子的相互作用尤为重要。为了研究在植物遭受逆境胁迫时,转录因子对下游靶基因的调控机制,本文综述了参与逆境胁迫的主要转录因子家族、转录因子的转录激活活性鉴定、转录因子和启动子互作分析技术及其在植物应答逆境胁迫中的应用,为全面、深入研究植物应答逆境胁迫时的基因表达调控机制提供参考。

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
