Achievements and perspectives in biochemistry concerning anthocyanin modification for blue flower coloration.
Genetic engineering of roses and other plants of floricultural importance to give them a truly blue petal color is arguably one of the holy grails of plant biotechnology. Toward this goal, bluish carnations and roses were previously engineered by establishing an exclusive accumulation of delphinidin (Dp)-type anthocyanins in their petals via the heterologous expression of a flavonoid 3',5'-hydr...
متن کاملMethylation mediated by an anthocyanin, O-methyltransferase, is involved in purple flower coloration in Paeonia
Anthocyanins are major pigments in plants. Methylation plays a role in the diversity and stability of anthocyanins. However, the contribution of anthocyanin methylation to flower coloration is still unclear. We identified two homologous anthocyanin O-methyltransferase (AOMT) genes from purple-flowered (PsAOMT) and red-flowered (PtAOMT) Paeonia plants, and we performed functional analyses of the...
متن کاملGeneration of blue chrysanthemums by anthocyanin B-ring hydroxylation and glucosylation and its coloration mechanism
Various colored cultivars of ornamental flowers have been bred by hybridization and mutation breeding; however, the generation of blue flowers for major cut flower plants, such as roses, chrysanthemums, and carnations, has not been achieved by conventional breeding or genetic engineering. Most blue-hued flowers contain delphinidin-based anthocyanins; therefore, delphinidin-producing carnation, ...
متن کاملGenetics and Biochemistry of Anthocyanin Biosynthesis.
Flavonoids represent a large class of secondary plant metabolites, of which anthocyanins are the most conspicuous class, dueto the wide range of colors resulting from their synthesis. Anthocyanins are important to many diverse functions within plants. Synthesis of anthocyanins in petals is undoubtedly intended to attract pollinators, whereas anthocyanin synthesis in seeds and fruits may aid in ...
متن کاملAnthocyanin Biosynthetic Genes and Their Application to Flower Color Modification through Sense Suppression
zThe coding sequence is compared for each pair of genes. Comparisons were done using the gap program of the Wisconsin GCG sequence analysis package. yCHS = chalcone synthase; CHI = chalcone isomerase; DFR = dihydroflavonol reductase. xFirst row for each plant pair presents the percent amino acid similarity. wSecond row for each plant pair presents the percent amino acid identity. vThird row for...
