Herbivory‐Induced Stomatal Opening Triggers the Dispersal of an Invasive Insect Herbivore
Advanced Science, EarlyView.The invasive leafminer Phthorimaea absoluta uniquely manipulates plant defenses by inducing stomatal opening in tomato. This response, mediated by the stomatal regulator IQM1, enhances the release of the repellent volatile benzaldehyde. This volatile triggers the dispersal of adult moths, facilitates colonization of new hosts, and leads to rapid ...
