The grape reaction product (GRP, GRP1 or 2-S-glutathionyl caftaric acid [1]) is a phenolic compound explaining the disappearance of caftaric acid from grape must during processing. [2] It is also found in aged red wines. [3] Its enzymatic production by polyphenol oxidase is important in limiting the browning of musts, [4] especially in white ...
Grapes can be eaten fresh or dried to produce raisins, sultanas, and currants. Grape leaves are used in the cuisine of many cultures. The fresh grapes can also be processed into juice that is fermented to make wine and vinegar. Cultivars of Vitis vinifera form the basis of the majority of wines produced around the world.
White grapes are believed to have arisen due to the extremely rare and independent mutation of two similar and adjacent regulatory genes, VvMYBA1 and VvMYBA2, in a red grape parent. Most grapevine cultivars can be divided into two groups – red and white – based on the presence or absence of anthocyanin in the skin of the fruit, which the ...
An image of multiple chromosomes, taken from many cells. Plant genetics is the study of genes, genetic variation, and heredity specifically in plants. [1] [2] It is generally considered a field of biology and botany, but intersects frequently with many other life sciences and is strongly linked with the study of information systems.
As an example, some rice strains are made by inserting new genetic material into a rice plant, [13] all the descendants of the genetically modified rice plant are a strain with unique genetic information that is passed on to later generations; the strain designation, which is normally a number or a formal name, covers all the plants that ...
Times are getting increasingly tough for many of California's wine grape growers. Wine-souring smoke from wildfires, grape-shriveling drought and global warming have all been playing an ...
U.S. consumers who were “tricked” into purchases they didn't want from Fortnite maker Epic Games are now starting to receive refund checks, the Federal Trade Commission said this week. Back in ...
Vitis (grapevine) is a genus of 81 accepted species [5] of vining plants in the flowering plant family Vitaceae. The genus consists of species predominantly from the Northern Hemisphere. It is economically important as the source of grapes, both for direct consumption of the fruit and for fermentation to produce wine.
