Abstract

A tree's travel companion: a fungal endophyte (Fusarium incarnatum) isolated from a viviparous propagule (embryo) of a mangrove tree produces typical plant defense oxylipins. Stable-isotope labeling experiments revealed that the endophyte biosynthesizes coriolic acid, didehydrocoriolic acid, and an epoxy fatty acid derived from linoleic acid by a process involving Δ(15)-desaturation and 13-lipoxygenation.
