| description | This entry represents a group of plant WRKY transcription factors. In Arabidopsis, WRKY1 binds to a 5'-CGTTGACCGAG-3' consensus core sequence which contains a W box, a frequently occurring elicitor-responsive cis-acting element []. WRKY33 regulates the antagonistic relationship between defense pathways mediating responses to the bacterial pathogen P. syringae and the necrotrophic pathogen B.cinerea []. It functions as a convergent substrate of CPK5/CPK6 and MPK3/MPK6, which cooperatively regulate camalexin (an antimicrobial compound) biosynthesis via the differential phospho-regulation of WRKY33 activity []. WRKY33 also functions with WRKY25 as positive regulator of salt stress response and abscisic acid (ABA) signalling []and with WRKY25/WRKY26 as positive regulator of plant thermotolerance by partially participating in ethylene-response signal transduction pathway []. WRKY5 from rice acts as positive regulator of leaf senescence being involved in onset and progression of this process []. It acts as negative regulator of drought tolerance by inhibiting ABA-induced stomatal closure during drought stress []. |
