Consumption of fresh fruits and vegetables has been linked both anecdotally and clinically to the prevention or alleviation of chronic diseases and provides essential nourishment to mankind. The muscadine grape, a fruit indigenous to the southeastern U.S., contains several phenolic compounds that act as antioxidants and also other compounds, such as resveratrol, that can perform as a chemopreve...

The skin color of grape berry is very important in the wine industry. The red color results from the synthesis and accumulation of anthocyanins, which is regulated by transcription factors belonging to the MYB family. The transcription factors that activate the anthocyanin biosynthetic genes have been isolated in model plants. However, the genetic basis of color variation is species-specific an...

Global gene expression was analyzed in the berry skin of two red grape cultivars, which can ('Jingyan') or cannot ('Jingxiu') synthesize anthocyanins after sunlight exclusion from fruit set until maturity. Gene transcripts responding to sunlight exclusion in 'Jingyan' were less complex than in 'Jingxiu'; 528 genes were induced and 383 repressed in the former, whereas 2655 genes were induced and...

Anthocyanins, flavan-3-ols, and flavonols are the three major classes of flavonoid compounds found in grape berry tissues. Several viticultural practices increase flavonoid content in the fruit, but the underlying genetic mechanisms responsible for these changes have not been completely deciphered. The impact of post-veraison sunlight exposure on anthocyanin and flavonol accumulation in grape b...

Grape (Vitis vinifera L.) has been the subject of many research studies because its phenolic compounds and antioxidant properties which are known to have positive effects on health. In this study, some phytochemical contents local standard grape varieties widely grown in Diyarbak?r province were determined. Amount total phenolic, anthocyanin flavonoid examined berry seed, pulp skin each variety...

The contribution of grape pomace on tannin concentration, composition and aroma profile Pinot noir wine was studied using different fermentation media to make up four treatments: GJ-P, juice plus pomace; MJ-P, model GJ, juice; MJ, juice. MJ-P treatment showed significantly lower amounts tannins, mean degree polymerisation (mDP), similar anthocyanin, a secondary compared the GJ-P treatment. Grap...

Anthocyanins, soluble sugars, and organic acids play a vital role in the color flavor of grape berries. N KH2PO4 are essential nutrients for growth development. However, research on effects foliar spraying skin grapes under different levels were not systematic. In this study, “Flame seedless” used as test material. There six treatments experiment, including low nitrogen (LN), + (LNK), moderate ...
