we created the double and triple knock-out mutants of three CYP94 genes, CYP94B1, CYP94B3, and CYP94C1. The mutations blocked the oxidation steps and caused JA-Ile to accumulate 3-4-fold the WT levels in the wounded leaves.
Title: Mutations in jasmonoyl-L-isoleucine-12-hydroxylases suppress multiple JA-dependent wound responses in Arabidopsis thaliana.

CYP94B3 and CYP94C1 are responsible for the production of oxidized derivatives of Jasmonoyl-Phenylalanine and Jasmonoyl-Isoleucine in wounded plants.
Title: Sequential oxidation of Jasmonoyl-Phenylalanine and Jasmonoyl-Isoleucine by multiple cytochrome P450 of the CYP94 family through newly identified aldehyde intermediates.

These results highlight the dual function of CYP94B3/C1 in antimicrobial defence.
Title: CYP94-mediated jasmonoyl-isoleucine hormone oxidation shapes jasmonate profiles and attenuates defence responses to Botrytis cinerea infection.

It was found that CYP94B3 also catalyzes the hydroxylation of jasmonoyl-L-valine and jasmonoyl-L-phenylalanine, and that these hydroxyl compounds accumulated after wounding and possessed lower activity than non-hydroxylated compounds.(cytohrome P-450 94B3)
Title: CYP94B3 activity against jasmonic acid amino acid conjugates and the elucidation of 12-O-?-glucopyranosyl-jasmonoyl-L-isoleucine as an additional metabolite.

These results identify CYP94B3/C1-mediated oxidation as a major catabolic route for turning over the JA-Ile hormone.
Title: Cytochromes P450 CYP94C1 and CYP94B3 catalyze two successive oxidation steps of plant hormone Jasmonoyl-isoleucine for catabolic turnover.
