Update: Stomatal defense a decade later

Stomatal defense, recognition of pathogens at the stomatal pore accompanied by stomatal closure to prevent their entry, was discovered ten years ago. Melotto et al. review what we’ve learned in the past decade about this key defense strategy. They discuss pathogen recognition, in which microbe-associated molecular patterns (MAMPs) are perceived by pattern recognition receptors (PRRs); downstream signaling including the contributions of ABA, salicylates and jasmonates; and the channels that mediate stomatal closure. They also review strategies by which pathogens are able to evade or suppress stomatal defenses, and the impact of environmental conditions on stomatal defenses. Plant Physol. 10.1104/pp.17.00183
