Dinor-12-oxo-phytodienoic acid conjugation with amino acids inhibits its phytohormone bioactivity in Marchantia polymorpha.

ABSTRACT: Jasmonates (JAs) are important phytohormones that regulate plant tolerance to biotic and abiotic stresses, and developmental processes. Distinct JAs in different plant lineages activate a conserved signaling pathway that mediates these responses: dinor-12-oxo-phytodienoic acid (dn-OPDA) isomers in bryophytes and lycophytes, and JA-Ile in most vascular plants. In many cases, the final responses triggered by these phytohormones depend on the accumulation of specialized metabolites. To identify compounds regulated by the dn-OPDA pathway in the liverwort Marchantia polymorpha, untargeted metabolomic analyses were carried out in response to wounding, a stress that activates the dn-OPDA pathway. A previously unreported group of molecules was identified from these analyses: dn-OPDA-amino acid con
