Eight-carbon volatiles in mushrooms and fungi: properties, analysis, and biosynthesis

Abstract

Eight-carbon volatiles are ubiquitous among fungi and characteristic of the fungal aroma. They are the product of the oxidation and cleavage of the fatty acid linoleic acid and are classified as oxylipins, molecules taking part in a wide range of biological processes. Their involvement in the fungal aroma, interactions with pests and pathogens, and reproductive events are reviewed here, as well as the enzymic systems involved in their biosynthesis.
