p-Hydroxybenzoyl-Glucose Is a Zwitter Donor for the Biosynthesis of 7-Polyacylated Anthocyanin in Delphinium[W]
Polyacylation of anthocyanin at the 7-position is crucial for the blue pigmentation of delphinium flowers. 7-Polyacylated anthocyanin is synthesized via a step-by-step reaction mediated by vacuolar… Expand
Dihydroflavonol 4-reductase activity is associated with the intensity of flower colors in delphinium
Flower color intensity is largely determined by the amount of accumulated anthocyanins. Delphinium flowers show a wide range of colors from pale pink to deep orange to red to dark blue. Here, we… Expand

In delphiniums (Delphinium grandiflorum), blue flowers are produced by the presence of 7-polyacylated anthocyanins. The polyacyl moiety is composed of glucose and p-hydroxybenzoic acid (pHBA). The… Expand
Sequence variations in the flavonoid 3′,5′-hydroxylase gene associated with reddish flower phenotypes in three delphinium varieties
Although delphiniums are famed for their blue flowers, a few varieties display reddish flowers, such the pale-pink garden varieties ‘Ehime Kou 9 (Kou 9)’ and ‘F1 Super Happy Pink (SHP),’ and the… Expand
