It is known that octadecanoids, i.e. jasmonic acid and related compounds are involved in plant defence reactions against (1) microbial pathogens, (2) herbivores and (3) damage by UV-B or UV-C light as well as (4) senescence and (5) mechanotransduction. Jasmonic acid is likely to occur ubiquitously in the plant kingdom, and it has also been found in some fungi. The pathway of octadecanoid biosynthesis was elucidated in the early 80s by Vick and Zimmerman. This review summarizes recent progress in the identification and characterization of octadecanoid biosynthetic enzymes and in the understanding of the regulation of octadecanoid biosynthesis.
