WebDec 19, 2024 · Jasmonic acid and its derivatives, such as jasmonic acid-isoleucine (JA-Ile) and methyl jasmonate (MeJA), are collectively referred to as jasmonates (JAs) [3, 4]. … 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. north iverton park road
