Diversification function of WRKY transcription factor
2010
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.
