WRKY33

Probable WRKY transcription factor 33

519 amino acids

Transcription factor. Interacts specifically with the W box (5'-TTGAC[CT]-3'), a frequently occurring elicitor-responsive cis-acting element. Involved in defense responses. Required for resistance to the necrotrophic fungal pathogen B.cinerea (PubMed:17059405, PubMed:21990940). Regulates the antagonistic relationship between defense pathways mediating responses to the bacterial pathogen P. syringae and the necrotrophic pathogen B.cinerea (PubMed:17059405). Required for the phytoalexin camalexin synthesis following infection with B.cinerea. Acts as positive regulator of the camalexin biosynthetic genes PAD3 (CYP71B15) and CYP71A13 by binding to their promoters (PubMed:21498677, PubMed:22392279). Acts downstream of MPK3 and MPK6 in reprogramming the expression of camalexin biosynthetic genes, which drives the metabolic flow to camalexin production (PubMed:21498677). Functions with WRKY25 as positive regulator of salt stress response and abscisic acid (ABA) signaling (PubMed:18839316). Functions with WRKY25 and WRKY26 as positive regulator of plant thermotolerance by partially participating in ethylene-response signal transduction pathway (PubMed:21336597). The DNA-binding activity of WRKY33 is increased by SIB1 and SIB2 (PubMed:21990940).

Belongs to the WRKY group I family.
