In the case of Pseudomonas syringae (Pst), water-soaking effectors stimulate abscisic acid (ABA) production and signaling, leading to stomatal closure. This lowers transpiration, increases water accumulation, and induces an apoplastic microenvironment positive for bacterial development. Stomata tend to be responsive to ecological problems, including light. Here, we reveal that a period of darkness is required for water-soaking, and therefore a consistent light regime abrogates stomatal closure by
