Abstract

Recent lipid-based findings suggest more direct roles for fatty acids and their degradation products in inducing/modulating various aspects of plant defense, e.g. as signaling molecules following stress responses that may regulate plant innate immunity. The synthesis of oxylipins is a highly dynamic process and occurs in both a developmentally regulated mode and in response to abiotic and biotic stresses. This mini-review summarizes the occurrence of free–and oxygenated fatty acid derivatives in plants as part of an orchestrated metabolic defense against pathogen attack. Oxygenated C18 derived polyunsaturated fatty acids were identified by untargeted metabolomics studies of a number of different plant-microbe pathosystems and may serve as potential biomarkers of oxidative stress. Untargeted metabolomics in combination with targeted lipidomics, can uncover previously unrecognized aspects of lipid mobilization during plant defense.
