development of a selective inhibitor of CYP707A, (1E,3R)-1-[4-(4-[[2-(2-butoxyethoxy)ethoxy]methyl]-1H-1,2,3-triazol-1-yl)phenyl]-4,4-dimethyl-2-(1H-1,2,4-triazol-1-yl)pent-1-en-3-ol, by structurally modifying S-uniconazole, which functions as an inhibitor of CYP707A and as a gibberellin biosynthetic enzyme, but with low yield. Design of CYP707A inhibitors, Abz-T compounds, that have simpler structures in which the 1,2,3-triazolyl ring of (1E,3R)-1-[4-(4-[[2-(2-butoxyethoxy)ethoxy]methyl]-1H-1,2,3-triazol-1-yl)phenyl]-4,4-dimethyl-2-(1H-1,2,4-triazol-1-yl)pent-1-en-3-ol has been replaced with a triple bond, by successful synthesis in shorter steps, resulting in greater yields than that of (1E,3R)-1-[4-(4-[[2-(2-butoxyethoxy)ethoxy]methyl]-1H-1,2,3-triazol-1-yl)phenyl]-4,4-dimethyl-2-(1H-1,2,4-triazol-1-yl)pent-1-en-3-ol. In the enzymatic assays, Abz-T compound (1E,3R)-4,4-dimethyl-1-[3-[4-(2,5,8,11-tetraoxadodecan-1-yl)-1H-1,2,3-triazol-1-yl]phenyl]-2-(1H-1,2,4-triazol-1-yl)pent-1-en-3-ol acts as a strong and selective inhibitor and is a more practical and effective inhibitor of CYP707A than (-)-Abz-E2B. Analysis of the biological effects in Arabidopsis thaliana reveals that (1E,3R)-4,4-dimethyl-1-[3-[4-(2,5,8,11-tetraoxadodecan-1-yl)-1H-1,2,3-triazol-1-yl]phenyl]-2-(1H-1,2,4-triazol-1-yl)pent-1-en-3-ol enhances abscisic acid effects more than (1E,3R)-1-[4-(4-[[2-(2-butoxyethoxy)ethoxy]methyl]-1H-1,2,3-triazol-1-yl)phenyl]-4,4-dimethyl-2-(1H-1,2,4-triazol-1-yl)pent-1-en-3-ol in seed germination and in the expression of ABA-responsive genes. Treatment with (1E,3R)-4,4-dimethyl-1-[3-[4-(2,5,8,11-tetraoxadodecan-1-yl)-1H-1,2,3-triazol-1-yl]phenyl]-2-(1H-1,2,4-triazol-1-yl)pent-1-en-3-ol induces stomatal closure and improves drought tolerance in Arabidopsis thaliana

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
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

ABA 8'-hydroxylase is the major and key P450 enzyme in the abscisic acid catabolism
physiological function
CYP707A1 mutant shows similar phenotype to wild-type in freshly harvested or after-ripen seeds. Seeds of CYP707A1 mutant has its dormancy entirely broken 18 d after ripening. NO enhances the tolerance to abscisic acid in CYP707A1 mutant during germination. Abscisic acid concentrations decrease rapidly during the first 12 h in CYP707A1 mutant. NO enhances the tolerance to abscisic acid in CYP707A1 mutant; CYP707A2 plays a major role in abscisic acid catabolism during the first stage of imbibition. CYP707A2 is involved in NO-induced dormancy break. CYP707A2 mutant shows a strong dormancy in freshly harvested seeds. CYP707A2 mutant still maintains strong dormancy until 30 d. NO does not enhance the tolerance to abscisic acid in CYP707A2 mutant during germination; CYP707A3 mutant shows similar phenotype to wild-type in freshly harvested or after-ripen seeds, with the seeds of CYP707A3 mutant having a slightly higher germination rate than the wild-type. Seeds of CYP707A3 mutant has its dormancy entirely broken 18 d after ripening. NO enhances the tolerance to abscisic acid in CYP707A3 mutant during germination
physiological function
-
CYP707A1 and CYP707A3 are involved in stomatal opening in response to high humidity. Cyp707a1 and cyp707a3 mutants display lower stomatal conductance under turgid conditions (relative humidity 60%) than the wild-type. Cyp707a3 mutant exhibits high abscisic acid levels even after transferring to high-humidity conditions, whereas, under similar conditions, the cyp707a1 mutant exhibits low abscisic acid levels comparable to the wild-type. Stomatal closure of the cyp707a1 mutant, but not cyp707a3 mutant, is abscisic acid hypersensitive when epidermal peel ias treated with exogenous abscisic acid. CYP707A3 reduces the amount of mobile abscisic acid in vascular tissues in response to high humidity, whereas CYP707A1 inactivates local abscisic acid pools inside the guard cells
