The ATP-binding cassette (ABC) protein superfamily constitutes one of the largest protein families known in plants. In this report, we performed a complete inventory of ABC protein genes in Vitis vinifera, the whole genome of which has been sequenced. By comparison with ABC protein members of Arabidopsis thaliana, we identified 135 putative ABC proteins with 1 or 2 NBDs in V. vinifera. Of these...

Wine quality is determined by the development of grape maturation, which highly dependent on climate variations. Extreme weather events are becoming more common, will affect productivity and grapes wine. Grape depends many factors, including weather, extreme influence berry size, skin thickness some key compounds, such as phenolics. In this work, ripening evolution phenolic content Vitis vinife...

Despite their low concentrations, secondary metabolites are essential to the organoleptic quality of grapevine fruit. Anthocyanins fruit skin cells principal components pigmentation red grape. Glycosylated aroma precursors (GAPs), i.e. alcohols, C13-norisoprenoids, phenols and terpenes determine potential juice resulting wine. The regulation sink/source (S/S) balance is considered as a one more...

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...

Flavan-3-ols consist of flavan-3-ol monomers and polymers with different degrees of polymerization (DP). In this study, flavan-3-ol extracts from grape seeds were well separated into three fractions including monomers, oligomers (2 < DP < 10) and polymers (DP > 10), by means of normal-phase HPLC-MS. The different patterns of these three fractions were analyzed in three Vitis vinifera cultivars ...

The biosynthesis of S-(3-hexan-1-ol)-glutathione (3MH-S-glut) and S-(3-hexan-l-ol)-L-cysteine (3MH-S-cys), which act as flavour precursors in wines, in Vitis vinifera grapes exposed to various environmental stress conditions is reported here. Ultraviolet (UV-C) irradiation, water deficit, and biological stimulation up-regulated 3MH-S-glut and 3MH-S-cys biosynthesis in grape leaves. 3MH-S-glut a...

Phenolic compounds were extracted from European and Japanese grapevine species (Vitis vinifera and V. coignetiae) seeds using 80% methanol or 80% acetone. The total content of phenolic compounds was determined utilizing Folin-Ciocalteu's phenol reagent, while the content of tannins was assayed by the vanillin and BSA precipitation methods. Additionally, the DPPH free radical and ABTS cation rad...

The family Phytoseiidae includes many species of predators involved in the control of mite pests of crops all over the world. In European vineyards, these natural enemies play a key role in plant protection as their presence usually makes the use of acaricides unnecessary. Each species has its specific biological features. It is thus of great interest to identify the species reported on grape, ...

This study was conducted Razakı grape variety (Vitis vinifera L.) and its vine which was aged 19 was grown on 5 BB rootstock in a vegetation period of 2014 in Afyon province in Turkey. In this research, it was investigated whether the applications of Control (C), 1/3 Cluster Tip Reduction (1/3 CTR), Shoot Tip Reduction (STR), 1/3 CTR + STR, Boric Acid (BA), 1/3 CTR + BA, STR + BA, 1/3 CTR + STR...

Background: Spine grape has gained attention in the field of wine science due to its good growth characteristics. Spine grape wine has been made by local residents for a long time. However, the scientific evaluation of spine wine has not been systemically documented compared to Vitis vinifera grape wines Methods: We compared 11 spine wines from south China (W1-W11) with 7 high-quality internati...
