Identification of the glucosyltransferase that mediates direct flavone C‐glucosylation in Gentiana triflora
A good correlation was observed between GtUF6CGT1 expression and C‐glycosylflavone accumulation in leaves and petals, and it is reported that this is the first reported C‐glucosyltransferase that mediates direct C‐ GLUCosylation of the flavone skeleton. Expand
p-Hydroxybenzoyl-Glucose Is a Zwitter Donor for the Biosynthesis of 7-Polyacylated Anthocyanin in Delphinium[W]
The question of which enzyme activities are necessary for catalyzing the transfer of Glc and pHBA moieties to 7-glucosylated anthocyanin was sought and it was found that these transfers were catalyzed by enzymes that use p-hydroxybenzoyl-Glc (pHBG) as a bifunctional acyl and glucosyl donor. Expand

  • 17 December 2013
Intensive characterization of the assigned carnation genes and comparison with those of other plant species revealed characteristic features of the carnation genome, a valuable resource for fundamental and applied research of carnation, especially for breeding new carnation varieties. Expand
The Role of Acyl-Glucose in Anthocyanin Modifications
The evolution of these enzymes has allowed delphinium and Arabidopsis to utilize unique donor molecules for production of highly modified anthocyanins. Expand
Crossbreeding of a metallic color carnation and diversification of the peculiar coloration by ion-beam irradiation
It is demonstrated that a factor generating the AVIs is inactivated anthocyanin malyltransferase gene, AVIs in water-clear vacuolar sap in the adaxial epidermal cells generate the novel metallic appearance, and ion beam breeding is a useful tool for increasing metallic colors by changing anthocianin structure and the level of AVIs.

Preparation of a Ammonia-Treated Lac Dye and Structure Elucidation of Its Main Component.
Ammonia-treatment of lac dye results in the generation of 4-aminolaccaic acids, an illegal colorant detected in several processed foods. Expand
Identification of the glutathione S-transferase gene responsible for flower color intensity in carnations
Results suggest that the DcGSTF2 gene is responsible forower color intensity in carnations. Expand
Structure of the acyl-glucose-dependent anthocyanin 5-O-glucosyltransferase gene in carnations and its disruption by transposable elements in some varieties
The pink, red and crimson petal colors of carnations (Dianthus caryophyllus) are produced by anthocyanins, and modification by 5-O-glucosyltransferase plays the most important role in glucosylation at the 5 position. Expand
Identification of the glucosyltransferase gene that supplies the p-hydroxybenzoyl-glucose for 7-polyacylation of anthocyanin in delphinium.
The conclusion that DgpHBAGT is responsible for in vivo synthesis of pHBG in delphiniums is supported, as a phylogenetic analysis of DgphBAGT amino acid sequences showed a close relationship with UGTs that act in acyl-glucose synthesis in other plant species. Expand
[Development of a Novel Method for Quantifying Quassin and Neoquassin in Jamaica Quassia Extracts Using the Molar Absorption Coefficient Ratio].
The proposed novel HPLC-based quantitation method employing the molar absorption coefficient ratios is a reliable tool for determining levels of quassin and neoquassin in food additives and processed foods. Expand
