Chrysanthemums (Chrysanthemum morifolium Ramat.) have no purple-, violet- or blue-flowered cultivars because they lack delphinidin-based anthocyanins. This deficiency is due to the absence of the flavonoid 3',5'-hydroxylase gene (F3'5'H), which encodes the key enzyme for delphinidin biosynthesis. In F3'5'H-transformed chrysanthemums, unpredictable and(More)
Flowers of the butterfly pea (Clitoria ternatea) accumulate a group of polyacylated anthocyanins, named ternatins, in their petals. The first step in ternatin biosynthesis is the transfer of glucose from UDP-glucose to anthocyanidins such as delphinidin, a reaction catalyzed in C. ternatea by UDP-glucose:anthocyanidin 3-O-glucosyltransferase (Ct3GT-A;(More)
Plants belong to the section Mina showed characteristic petal pigmentation among Ipomoea plants. For example, petals of Ipomoea hederifolia var. lutea display yellow color derived from carotenoids and those of Ipomoea quamoclit display red color derived from pelargonidin-based anthocyanins. In this study, the pigment composition and the expression patterns(More)
