描述:(±)-7-epi Jasmonic acid is the major metabolite of the 12-oxo phytodienoic acid pathway of the metabolism of 13(S)-hydroperoxy linolenic acid in plants. Initially synthesized as (+)-7-epi jasmonic acid, this more active and biologically relevant form of the hormone quickly epimerizes to the more stable isomer (−)-7-jasmonic acid.1,2 (±)-7-epi Jasmonic acid is a plant growth regulator that activates various signal transduction pathways with both growth promoting and inhibitory functions, perhaps in response to stress.3,4
