Cytochromes P450 play important roles in biosynthesis of flavonoids and their coloured
class of compounds, anthocyanins, both of which are major floral pigments. The number of …

Flavonoids are major constituents of flower colour. Plants accumulate specific flavonoids
and thus every species often exhibits a limited flower colour range. Three cytochromes P450 …

The substitution pattern of anthocyanin pigments is a main determinant of flower color.
Flavonoid 3′, 5′-hydroxylase (F3′ 5′ H) is a cytochrome P450 enzyme (Cyt P450) that …

Recently marketed genetically modified violet carnations cv. Moondust and Moonshadow
(Dianthus caryophyllus) produce a delphinidin type anthocyanin that native carnations …

The long history of the search for blue roses, apparently unattainable by traditional breeding,
is noted. The anthocyanin pathway, which produces blue flowers via delphinidin 3-glucoside …

Within the secondary metabolite class of flavonoids which consist of more than 9000 known
structures, flavones define one of the largest subgroups. Their natural distribution is …

Flavonoids, in particular the anthocyanins, are responsible for flower colour in manyspecies.
The dihydroflavonols represent abranch point in flavonoid biosynthesis, being the …

Abstract Cytochrome P450 cDNAs, AFNS2 and TFNS5, were isolated from snapdragon and
torenia petal cDNA libraries, respectively, based on the sequence homology with licorice …

Flavonols are important co‐pigments in flower colour and are also essential for pollen tube
growth. In petunia, flavonol synthesis is controlled by the Fl locus. Flavonol synthase (FLS) …

Some angiosperms are limited to a range of possible flower colors. This limitation can be
due to the lack of an anthocyanin biosynthetic gene or to the substrate specificity of a key …
