Anthocyanin 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...
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 کاملFlower color modification of gentian plants by RNAi-mediated gene silencing
RNA interference (RNAi) is an efficient and powerful technique for gene silencing compared with antisense and sense suppression. Here we report adaptation of RNAi technology to modify flower colors in gentian, targeted for suppression of three anthocyanin biosynthetic genes; chalcone synthase (CHS), anthocyanidin synthase (ANS) and flavonoid 3 ,5 -hydroxylase (F3 5 H). The petals of transgenic ...
متن کاملS-adenosylmethionine-dependent protein methylation in mammalian cytosol via tyrphostin modification by catechol-O-methyltransferase.
It has previously been shown that incubation of mammalian cell cytosolic extracts with the protein kinase inhibitor tyrphostin A25 results in enhanced transfer of methyl groups from S-adenosyl-[methyl-3H]methionine to proteins. These findings were interpreted as demonstrating tyrphostin stimulation of a novel type of protein carboxyl methyltransferase. We find here, however, that tyrphostin A25...
متن کاملModification of Flower Color Pigments and Color Composition with Hormonal Treatments and Sucrose in Tulipa gesneriana ‘Kingsblood’
Three separate experiments were conducted to investigate the interplay between three phytohormones and sucrose for the change of flower color composition and the plant secondary metabolites in Tulipa. The variations of the physiological and morphological characteristics, with ABA at 5 and 10 mg/L (as experiment one), GA3 at 300 and 500 mg/L (as experiment two), 50 and 10...
