Both 12-OPDA and 10-OPEA equally promote the transcription of numerous defense genes encoding glutathione S-transferases, cytochrome P450s, and pathogenesis-related proteins however, 10-OPEA activity diverges in the context of reduced protease inhibitor transcript accumulation. Despite structural similarity to jasmonates, physiological roles for 10-OPEA have remained unclear. An additional and conceptually parallel pathway involving 9-LOX activity on linoleic acid leads to the production of 10-oxo-11-phytoenoic acid (10-OPEA). As signals, jasmonates have related yet distinct roles in the regulation of plant resistance against insect and pathogen attack. The enzymatic action of 13-LOX on linolenic acid enables production of 12-oxo-phytodienoic acid (12-OPDA) and its downstream products, jointly known as jasmonates. Plant cellular damage promotes the interaction of lipoxygenases (LOX) with free fatty acids to yield 9- and 13-hydroperoxides which are further metabolized into diverse oxylipins. The maize death acids, 10-oxo-11-phytoenoic acid and derivatives, are rapidly induced phytoalexins with multiple biological activitiesĮxpression profiling by high throughput sequencing GEO help: Mouse over screen elements for information.
