Abstract
cis‐Jasmone is a highly appreciated fragrance and plant‐derived signal molecule that controls pollination, attracts parasitoids of attacking herbivores, and serves as an intra‐ and interspecific signal that controls gene expression. cis‐Jasmone is produced from linolenic acid along the jasmonic acid cascade. In addition to the conversion of jasmonic acid into cis‐jasmone, a novel pathway might exist that converts cis‐oxophytodienoic acid (OPDA), an early precursor of jasmonic acid, into iso‐OPDA. The planar iso‐OPDA is degraded by β‐oxidation to 3,7‐didehydrojasmonic acid, which yields cis‐jasmone by spontaneous decarboxylation. The degradation of iso‐OPDA to cis‐jasmone is demonstrated for many plant species and the yeast Saccharomyces cerevisiae.
