WRKY plant-specific group of transcription factors that play important role in many plant metabolic and developmental processes such as;
a) It contain a 30 amino acid region named for the conserved amino acid sequence WRKYGQK in its N-terminal domain
b) It is an important regulators of plant–pathogen interactions as well as senescence
c) WRKY53 is involved in the regulation of dark-induced leaf senescence
d) In Arabidopsis, leaf senescence is delayed in knockout mutants of the WRKY53 gene
e) WRKY53 also binds to the promoter of the WRKY53 gene, inhibiting its own expression in a negative feedback loop
