Biosynthesis of jasmonic acid
WebApr 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]. In recent years, an increasing number of studies have demonstrated that GA synthesis and degradation are tightly regulated in response to abiotic stresses [ 27 ... WebApr 1, 2024 · For the first time in 25 years, a new pathway for biosynthesis of jasmonic acid (JA) has been identified. JA production takes place via 12-oxo-phytodienoic acid (OPDA) including reduction by OPDA reductases (OPRs). A loss-of-function allele, opr3-3, revealed an OPR3-independent pathway converting OPDA to JA.
