New checkpoints in stomatal defense

Trends Plant Sci. 2013 Jun;18(6):295-7. doi: 10.1016/j.tplants.2013.03.007. Epub 2013 Apr 11.

Abstract

Recent reports have revealed new guard cell signaling elements that function in stomatal defense in Arabidopsis thaliana (Arabidopsis). We discuss here the role of oxylipins, salicylic acid (SA), and abscisic acid (ABA) in stomatal immunity in response to the bacterial pathogen Pseudomonas syringae.
