Transcription factor. Interacts specifically with the W box (5'-(T)TGAC[CT]-3'), a frequently occurring elicitor-responsive cis-acting element (By similarity). Functions with WRKY25 and WRKY33 as positive regulator of plant thermotolerance by partially participating in ethylene-response signal transduction pathway (PubMed:21336597). Interacts with VQ10. A number of isoforms are produced. According to EST sequences. By salicylic acid (PubMed:11449049). Induced by heat stress (PubMed:21336597). Belongs to the WRKY group I family.
