Colneleic Acid

Colneleic acid is a divinyl ether oxylipin and an active metabolite of linoleic acid (Cay-90150, Cay-90150.1, Cay-21909) that has been found in potatoes. It is formed from linoleic acid by 9-lipoxygenase (9-LO) via a (±)9-HpODE (Cay-10705) intermediate and divinyl ether synthase. Colneleic acid decreases P. infestans hyphae growth when used at concentrations of 15, 75, and 150 µM and reduces P. infestans cystospore germination in a concentration-dependent manner. The levels of colneleic acid are increased in potato leaves following P. infestans infection and in rice seedlings following brown planthopper feeding.Formal Name: 9-[(1E,3Z)-1,3-nonadien-1-yloxy]-8E-nonenoic acid.
