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
[3]
. WRKY33 regulates the antagonistic relationship between defense pathways mediating responses to the bacterial pathogen P. syringae and the necrotrophic pathogen B.cinerea
[5]
. 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
[4]
. WRKY33 also functions with WRKY25 as positive regulator of salt stress response and abscisic acid (ABA) signalling
[6]
and with WRKY25/WRKY26 as positive regulator of plant thermotolerance by partially participating in ethylene-response signal transduction pathway
[7]
. WRKY5 from rice acts as positive regulator of leaf senescence being involved in onset and progression of this process
[2]
. It acts as negative regulator of drought tolerance by inhibiting ABA-induced stomatal closure during drought stress
[1]
.
