WRKY transcription factors are one of the largest families of transcriptional regulators in plants which form integral parts of signaling webs that modulate many plant processes. The WRKY proteins contain a DNA-binding region of approximately 60 amino acids (the WRKY domain) at its amino terminal end and a novel zinc-finger motif at the carboxyl terminus, this features give this transcription factor family name “WRKY”. Novel DNAbinding protein, the WRKY protein, show high affinity binding to a DNA sequence, the W-box sequence (C/T)TGAC(C/T), which is found in the promoter region of many genes. (WRKY: W: Tryptophan, R: Arginine, K: Lysine, Y: Tyrosine)
