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 beta-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.
顺式茉莉酮是一种备受青睐的香料和植物源信号分子，它控制授粉、吸引攻击食草动物的寄生蜂，并作为控制基因表达的种内和种间信号。顺式茉莉酮是由亚麻酸沿着茉莉酸级联反应产生的。除了茉莉酸转化为顺式茉莉酮外，可能还存在一条将茉莉酸的早期前体顺式氧代植物二烯酸（OPDA）转化为异OPDA的新途径。平面异OPDA通过β-氧化降解为3,7-二脱氢茉莉酸，后者通过自发脱羧产生顺式茉莉酮。许多植物物种和酿酒酵母都证明了异OPDA降解为顺式茉莉酮的过程。
