Its biosynthesis starts from the fatty acid linolenic acid, which is oxygenated by lipoxygenase (13-LOX), forming a hydroperoxide. This peroxide then cyclizes in the presence of allene oxide synthase to form an allene oxide. The rearrangement of allene oxide to form 12-oxophytodienoic acid is catalyzed by the enzyme allene oxide cyclase. A series of β-oxidations results in 7-isojasmonic acid. In the absence of enzyme, this isojasmonic acid isomerizes to jasmonic acid. rockland maine town managerWebFeb 5, 2024 · A solid-state fermentation (SSF) method is developed for high production of Jasmonic acid using Lasiodiplodia iranensis and results indicate that JA biosynthesis occurs in the α-linolenic acid metabolic pathway, of which 13 (S)-HpOTrE is a key intermediate metabolite and both 13-S-HotrE and traumatic acid are byproducts of the … other words for buckleWebApr 11, 2024 · Phytohormones, such as abscisic acid (ABA), ethylene, jasmonic acid (JA), and salicylic acid (SA), are crucial factors in controlling plant adaptations to environmental stresses [62,63].
