From: WRKY transcription factors: evolution, binding, and action
Rice (a) and Arabidopsis (b) WRKY regulation in multiple pathways. OsWRKY and AtWRKY transcription factors (TFs) participate in response to various cellular and environmental stimuli. WRKY TFs may be activated by protein kinases and interaction with receptor-(like) proteins. Interaction among WRKY proteins or with other TFs, and the existence of WRKY cascade complicate WRKY regulatory network. For the details see the main text. Arrow in black for positive, blue for negative, and red for both positive and negative regulations; double arrow heads in green for interaction; WRKY in red for feedback positive and yellow for feedback negative regulations; word in blue for negatively regulated
