   1.14.14.137 | evolution |
the enzyme belongs to the cytochrome P450 CYP707A family. The expressions of isozymes AhCYP707A1 and AhCYP707A2 play an important role in abscisic acid catabolism in peanut, particularly in response to osmotic stress |

deletion in TaABA8'OH1 leads to increased abscisic acid level in the spikes and therefore increased drought sensitivity, phenotype, overview. Germination of the cyp707a1 cyp707a2 seeds appear not to be affected by the cold treatment, which induces early germination phenotype in the control wild-type and TaCYP707A1B-C seeds of transgenic Arabidospis thaliana, similar rate of transpirational water loss between the wild-type and mutant TaNCED2A-OE, cyp707a1/cyp707a2 and TaCYP707A1B-C lines during the entire period of dehydration |

| 1.14.14.137 | 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 |

| 1.14.14.137 | 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 |

| 1.14.14.137 | metabolism |
biosynthesis and catabolism of abscisic acid (ABA) in plants are primarily regulated by 9-cis-epoxycarotenoid dioxygenases (NCEDs) and ABA 8'-hydroxylase (ABA8'OH), respectively |

| 1.14.14.137 | metabolism |
comparison of abscisic acid (ABA) metabolism and signaling in roots of flooded and water stressed plants of Carrizo citrange reveals that the hormone depletion is linked to the upregulation of CsAOG, involved in abscisic acid glycosyl ester (ABAGE) synthesis, and to a moderate induction of catabolism (CsCYP707A, an ABA 8'-hydroxylase) and buildup of dehydrophaseic acid (DPA). Drought strongly induces both ABA biosynthesis and catabolism (CsNCED1, 9-cis-neoxanthin epoxycarotenoid dioxygenase1, and CsCYP707A) rendering a significant hormone accumulation. In roots of flooded plants, restoration of control abscisic acid levels after stress release is associated to the upregulation of CsBGLU18 (an abscisic acid beta--glycosidase) that cleaves ABAGE |

hydroxylation at the 8'-position of abscisic acid appears to be the key step of abscisic acid catabolism, and this reaction is catalyzed by ABA 8'-hydroxylase |
