Postinvasive Bacterial Resistance Conferred by Open Stomata in Rice

The role of Abscisic Acid in plant immunity is complex, inducing defense against some pathogens and inducing resistance against others. In this article, Dandan Zhang and colleagues show that in rice, preventing Abscisic Acid from closing stomata increases resistance to Xanthomonas pathogens, likely by decreasing water availability in the leaf interior. The broad spectrum resistance they see suggests that leaf water status plays an important role in resistance to pathogens and may indicate future targets for disease management.
