A key response of plants to moisture stress is stomatal closure, a process mediated by the phytohormone abscisic acid (ABA). Closure is affected by changes in the turgor of the stomatal guard cell. The transcription factor WRKY1 is a part of the regulatory machinery underlying stomatal movements, and through this, in the plant’s response to drought stress. The loss-of-function T-DNA insertion mutant wrky1 was particularly sensitive to ABA, with respect to both ion channel regulation and stomatal movements, and less sensitive to drought than the wild type. Complementation of the wrky1 mutant resulted in the recovery of the wild type phenotype. WRKY1 is thought to act as a negative regulator in guard cell ABA signalling.
