Biosynthesis of anthocyanins and their regulation in colored grapes.

The expression of SlMyb7-like, anthocyanin biosynthetic genes and the content of anthocyanin in the miR828 overexpressed tomatoes were lower than that in control plants under phosphate deficiency.

Expression of anthocyanin biosynthesis pathway genes in red and white grapes.

Under the normal phosphate condition, the expression of anthocyanin biosynthetic genes in the miR828 over-expressed tomatoes decreased by 30%-60% and the content of anthocyanin decreased by 40%.

Myb-related genes of the Kyoho grape (Vitis labruscana) regulate anthocyanin biosynthesis.

Because of the commercial importance of grapes ( spp.), it is important to understand how grape coloration is affected by genetic and environmental factors, as this knowledge may contribute to more stable production of high-quality grapes. The color of berry skins is determined mainly by the quantity and composition of anthocyanins. This review summarizes the results of recent studies of the genetic and environmental regulation of anthocyanin biosynthesis in grape berry skin: (i) The myeloblastosis (MYB) haplotype composition at the color locus is the major genetic factor that determines the anthocyanin content. (ii) The MYB haplotype composition at the color locus and the locus are major genetic determinants of the ratios of tri- to di-hydroxylated anthocyanins and of methylated to non-methylated anthocyanins. (iii) The accumulation of anthocyanins depends on both low temperature and light, and the two factors have a synergistic effect on the expression of genes within the anthocyanin biosynthesis pathway. (iv) Comprehensive transcriptome analysis using a grape oligo-DNA microarray let my research group identify many candidate genes involved in low-temperature-induced abscisic acid signaling and light signaling networks related to anthocyanin accumulation in grape berry skin. These findings will allow prediction of the skin color of grapes from seedlings at a very young stage by examining the MYB haplotype composition. Furthermore, these results will contribute to a fuller understanding of how grape coloration is affected by environmental factors, thereby helping grape growers to develop cultivation techniques that contribute to the production of highly pigmented grapes.

REGULATION OF ANTHOCYANIN BIOSYNTHESIS

Regulation of anthocyanin and stilbene biosynthesis in Vitis vinifera L.

The expression of anthocyanin biosynthesis pathway structural genes VvCHS, VvLDOX, VvUFGT, and regulatory gene VvmybA1 and light signal transcription factor VvHY5 were analyzed by real-time PCR.

The induction ability of different color fruit bags on VvHY5 expression was different, like that the blue paper bag was the strongest and the red paper bag was the worst.【Conclusion】Blue paper bag is of benefit to grape anthocyanin biosynthesis, while red paper bag is poor.
