In continuous light (left), HopM1 and AvrE1-mediated stimulation of ABA biosynthesis and signaling occurs. However, elevated SA accumulation in continuous light conditions ensures that stomata remain open despite the pro-closure influence of ABA, thus preventing water-soaking. When plants experience a period of darkness (right), the pro-closure influence of ABA predominates, possibly due to reduced SA accumulation, leading to water-soaking.
