Dinor-12-oxo Phytodienoic Acid (dn-OPDA) is a biologically active oxylipin derived from linolenic acid, playing a key role in plant defense mechanisms and stress responses. It is an intermediate in the biosynthesis of jasmonic acid, a vital plant hormone involved in regulating growth, development, and responses to environmental stresses such as wounding, herbivory, and pathogen attacks. dn-OPDA also has signaling functions, modulating gene expression and activating defense pathways independently of jasmonic acid. Its role in plant stress physiology and signaling makes Dinor-12-oxo Phytodienoic Acid a critical molecule for research in plant biology and agricultural science.
