Transcription repressor. Interacts specifically with the W box (5'-(T)TGAC[CT]-3'), a frequently occurring elicitor-responsive cis-acting element. Regulates, probably indirectly, the activation of defense-related genes during defense response. Modulates plant innate immunity against X.oryzae pv. oryzae (Xoo). Regulates negatively the basal defense responses to the compatible fungus M.oryzae. Induced by biotic elicitors (e.g. fungal chitin oligosaccharide). Accumulates in response to M.oryzae. The WRKY domain is required to bind DNA. Belongs to the WRKY group II-a family. Truncated N-terminus.
