A switch off in jasmonate(JA)signaling by hydroxylation upon wounding was described in 2008(Miersch et al.,2008).This initiated the cloning of CYP450 enzymes involved in hydroxylation and carboxylation of JA and its amino acid conjugate JA-le,the most active form of JA compounds(reviewed by Wasternack and Feussner[2018]and Heitz et al.[2019]).Due to the central role of JA and JA-lle in plant stress responses and development(Wasternack and Hause,2013),catabolism of JA and its derivatives is an essential component in the sustainment of homeostasis of active JA compounds(Howe et al.,2018;Heitz et al.,2019).Catabolism of JA and JAIle takes place by JA-induced oxygenases(JOXs),also named JA-oxidases(JAOs),and by hydroxylation(CYP94B3/B1)followed by carboxylation(CYP94C1),respectively(Heitz et al.,2019).Another reaction performed by IAR3/ILL6 results in the deconjugation of JA-lle and 12-OH-JA-le to JA and 12-OH-JA,respectively(Heitz et al.,2019;Wasternack and Feussner,2018).
