WRKY转录因子功能的多样化

WRKY is a superfamily of transcription factors existing abroad in plants, containing a conserved WRKYGQK domain and having a zinc finger motif. The expression of WRKY is induced by pathogen, wounding, SA, etc. WRKY proteins regulate target genes’ expression via binding the（T）（T）TGAC（C/T） sequence(W-box) located in their promoter regions. WRKY proteins involved in many physiological processes, such as resistance, wounding, development, senescence. In this article, we primarily interpret their structure and review the current progresses on their functions.
