Abstract :
[en] Plant oxylipins are produced under a wide range of stress conditions, and even though they are well known to activate stress-related signalling pathways, the non-signalling roles of phyto-oxylipins are poorly understood. We describe oxylipins as direct biocidal agents and propose that structure-function relationships play here a pivotal role. Indeed, based on their chemical configuration, plant oxylipins, such as reactive oxygen and electrophile species, activate defence-related genes expression. We also propose that their ability to interact with pathogen membranes is important, but still misunderstood, and that they are involved in cross-kingdom communication. Taken as a whole, the current literature suggests that plant oxylipins have a high potential as biocontrol agents. However, the mechanisms underlying these multi-faceted compounds remain largely unknown.
