Identification of the glucosyltransferase that mediates direct flavone C‐glucosylation in Gentiana triflora
The major flavonoids accumulated in leaves of Japanese gentian (Gentiana triflora) were determined as isoorientin (luteolin 6‐C‐glucoside) and isoorientin 4′‐glucoside. A cDNA (GtUF6CGT1) was… Expand

Dahlias (Dahlia variabilis) exhibit a wide range of flower colours because of accumulation of anthocyanin and other flavonoids in their ray florets. Two lateral mutants were used that spontaneously… Expand
Endogenous post-transcriptional gene silencing of flavone synthase resulting in high accumulation of anthocyanins in black dahlia cultivars
Black color in flowers is a highly attractive trait in the floricultural industry, but its underlying mechanisms are largely unknown. This study was performed to identify the bases of the high… Expand
Flower colours and pigments in Disa hybrid (Orchidaceae).
Abstract Flower colours and the composition of pigments in the perianths of five cultivars of Disa orchids were analyzed. Carotenoids were major pigment components in the orange-red flowers of ‘Dawn… Expand

Determination of Minor Floral Anthocyanins in a Red-flowered Petunia
Minor floral anthocyanins of a red-flowered petunia were isolated and determined by chromatographic and spectroscopic methods. Petunidin 3-glucoside (1.7%) and malvidin 3-glucoside (1.3%) were… Expand
Simultaneous post-transcriptional gene silencing of two different chalcone synthase genes resulting in pure white flowers in the octoploid dahlia
Garden dahlias (Dahlia variabilis) are autoallooctoploids with redundant genes producing wide color variations in flowers. There are no pure white dahlia cultivars, despite its long breeding history.… Expand
An unusual acylated malvidin 3-glucoside from flowers of Impatiens textori Miq. (Balsaminaceae).
Acylated malvidin 3-glucoside was isolated from the purple flowers of Impatiens textori Miq. as a major anthocyanin component along with malvidin 3-(6''-malonyl-glucoside). Its structure was… Expand
Post-transcriptional silencing of chalcone synthase is involved in phenotypic lability in petals and leaves of bicolor dahlia (Dahlia variabilis) ‘Yuino’
AbstractMain conclusionPost-transcriptional gene silencing (PTGS) of a chalcone synthase (DvCHS2) occurred in the white part of bicolor petals and flavonoid-poor leaves; however, it did not in red… Expand
