Abstract
Stomata-pathogen interactions are a fascinating part of plant immunity. Stomata perceive pathogens and close; in turn, successful pathogens reopen stomata to enter the apoplast. Recent studies by Hu et al. and Roussin-Leveillee et al. demonstrate that, following entry, Pseudomonas syringae closes stomata and, thus, reduces transpiration in infected leaves, adding another layer of complexity to the stomata-pathogen interaction.
