Stilbenoids, a family of polyphenols known for the complexity of their structure and for their diverse biological activities, occur with a limited but heterogeneous distribution in the plant kingdom. The most prominent stilbene containing plant family, the Vitaceae, represented by the famous wine producing grape vines Vitis vinifera L., is one of the richest sources of novel stilbenes currently...

Grape (Vitis vinifera) produces a variety of secondary metabolites, which can enhance nutrients and flavor in fruit wine. Uridine diphosphate-glycosyltransferases (UGTs) are primarily responsible for the availability metabolites by glycosylation modification. Here, total 228 putative UGTs were identified V. vinifera, VvUGTs clustered into 15 groups (A to O) unevenly distributed on 18 chromosome...

The increasing level of hazardous residues in the environment and food chains has led the European Union to restrict the use of chemical fungicides. Thus, exploiting new natural antagonistic microorganisms against fungal diseases could serve the agricultural production to reduce pre- and post-harvest losses, to boost safer practices for workers and to protect the consumers' health. The main aim...

Developed from crosses between Vitis vinifera and North American Vitis species, interspecific hybrid grape varieties are becoming economically significant in northern areas, where they are now extensively grown for wine production. However, the varietal differences between interspecific hybrids are not well defined, nor are the relationships between hybrid grape and wine composition, which caus...

This project aimed at breeding new seedless grape cultivars by embryo rescue through three hybridization methods: 1) using cross-breeding between seedless Vitis vinifera cultivars and wild Chinese Vitis spp; 2) crossing with two seedless cultivars, and 3) hybridization between grapes of different ploidy. Genotype, sampling times, and media were confirmed to play important roles in this system. ...

Viticulture and wine production are indispensable elements of Europe’s cultural civilizational identity. The study aimed to characterize raw materials obtained from the common grape vine Vitis vinifera L., their use in cosmetology, presentation vinotherapy as an interesting, cosmetically useful approach utilize body care human well-being improvement. In Poland, treatments becoming a popular sup...

Protective effects of grape (Vitis vinifera) seed (GSE), Citrus spp. fruits (CE) and olive {Olea europaea L.) leaf (OL) extracts, the flavonoids diosmin and rutin, widely used as pharmaceuticals, and dimethylsulphoxide (DMSO) against chromosomal damage induced by X-rays were determined by using the micronucleus test for anticlastogenic activity. The reduction of the frequency of micronucleated ...

The Cosmetic Ingredient Review Expert Panel (Panel) assessed the safety of 24 Vitis vinifera (grape)-derived ingredients and found them safe in the present practices of use and concentration in cosmetics. These ingredients function in cosmetics mostly as skin-conditioning agents, but some function as antioxidants, flavoring agents, and/or colorants. The Panel reviewed the available animal and c...

the effect of postharvest uv-c irradiation on phenolic compounds accumulation was investigated in berries of ‘rishbaba’ table grape (vitis vinifera cv. rishbaba). grape clusters were harvested at mature stage and irradiated with uv-c using fluorescent germicidal lamp (30 w, 90 cm) with a peak emission at 254 nm for 0 (control), 5 and 10 min. uv-c treatment had significant effect on individual p...

abstract this experiment was carried out to determine the effects of proline and ascorbic acid on chilling injury, electrolyte leakage, lipid peroxidation, peroxide hydrogen and antioxidant enzymes activity of thompson grape (vitis vinifera l.) fruit. grape fruits were treated by 0 (control), 250 and 500 µm proline and 0 (control), 2 and 4% ascorbic acid and their combinations, then stored at 1...
