OPDA

12-Oxo phytodienoic acid (12-oxo PDA) is an endogenous signal converter that increases alkaloid biosynthesis in E. californica cell cultures, increases b. dioica tendril curls, And inhibited jasmonic acid-induced programmed cell death in conditioned A. fru mutants.

1dinor-12-oxo-Phytodienoic acid (dinor-OPDA) serves as an intermediate in the biosynthesis of jasmonic acid from hexadecatrienoic acid, playing a crucial role in the jasmonate pathway in plants. This pathway oxygenates and modifies certain unsaturated fatty acids to produce plant hormones critical for processes such as senescence, flower development, mechanotransduction, and response to herbivory. Additionally, dinor-OPDA can be incorporated into glycerolipids and galactolipids, including specific arabidopsides.
