Transcription repressor (By similarity). Interacts specifically with the W box (5'-(T)TGAC[CT]-3'), a frequently occurring elicitor-responsive cis-acting element. Negative regulator of both gibberellic acid (GA) and abscisic acid (ABA) signaling in aleurone cells, probably by interfering with GAM1, via the specific repression of GA- and ABA-induced promoters (By similarity). Expressed in aleurone cells. Mostly expressed in aleurone layers and leaves, and, to a lower extent, in roots, panicles and embryos. In dry seeds, expressed in aleurone cells and embryos. Levels drop rapidly but transiently in the embryos of imbibed seeds. Induced by abscisic acid (ABA) in aleurone cells, embryos, roots and leaves (PubMed:25110688). Slightly down-regulated by gibberellic acid (GA) (By similarity). Accumulates in response to jasmonic acid (MeJA) (PubMed:16919842). The WRKY domain is required to bind DNA. Belongs to the WRKY group II-a family.
