General Information | Comment | Organism |
---|---|---|
metabolism | ABA 8'-hydroxylase is a key enzyme in the oxidative catabolism of abscisic acid. Endogenous abscisic acid content is modulated by a dynamic balance between biosynthesis and catabolism, which are regulated by NCED1 and CYP707As transcripts, respectively, during fruit maturation and under stress conditions, overview | Prunus avium |
metabolism | ABA 8'-hydroxylase is a key enzyme in the oxidative catabolism of abscisic acid. Endogenous abscisic acid content is modulated by a dynamic balance between biosynthesis and catabolism, which are regulated by NCED1 and CYP707As transcripts, respectively, during fruit maturation and under stress conditions, overview. Application of abscisic acid induces the expression of CYP707A1-CYP707A3 as well as PacNCED1, encoding 9-cis-epoxycarotenoid dioxygenase, but downregulates the CYP707A4 transcript level. Expressions of CYP707A1 and CYP707A3 are strongly increased by water stress, while no significant differences in CYP707A2 and CYP707A4 expression are observed between dehydrated and control fruits | Prunus avium |
physiological function | all four CYP707As are expressed at varying intensities throughout fruit development and appear to play overlapping roles in abscisic acid catabolism throughout sweet cherry fruit development | Prunus avium |
