1 Biosynthesis of the phytohormone jasmonoyl-isoleucine (JA-Ile) requires reduction of the JA precursor 12-oxo-phytodienoic acid (OPDA) by OPDA reductase 3 (OPR3). 12-oxophytodienoic acid oxophytodienoate-reductase 3 Arabidopsis thaliana
2 Biosynthesis of the phytohormone jasmonoyl-isoleucine (JA-Ile) requires reduction of the JA precursor 12-oxo-phytodienoic acid (OPDA) by OPDA reductase 3 (OPR3). 12-oxophytodienoic acid oxophytodienoate-reductase 3 Arabidopsis thaliana
3 Our results demonstrate that in the absence of OPR3, OPDA enters the beta-oxidation pathway to produce 4,5-ddh-JA as a direct precursor of JA and JA-Ile, thus identifying an OPR3-independent pathway for JA biosynthesis. 12-oxophytodienoic acid oxophytodienoate-reductase 3 Arabidopsis thaliana
