Background: Peptic ulcer disease is a most common disease, whose incidence is increasing presently on account of demanding stressful life. Objectives: To evaluate and compare the antiulcer activity of the extracts of seed and skin of Vitis Vinifera (Grape) using two different doses (100 & 200 mg/kg). Methods: The extracts of seed and skin of Vitis Vinifera were investigated for their anti-ulcer...

We gathered genomic data from grapes (Vitis vinifera ssp. vinifera), a clonally propagated perennial crop, to address three ongoing mysteries about plant domestication. The first is the duration of domestication; archaeological evidence suggests that domestication occurs over millennia, but genetic evidence indicates that it can occur rapidly. We estimated that our wild and cultivated grape sam...

Grape canes, also named vine shoots, are well-known viticultural byproducts containing high levels of phenolic compounds, which associated with a broad range health benefits. In this work, grape canes (Vitis vinifera cv. Pinot noir) were extracted in 750 L pilot-plant reactor under the following conditions: temperature 80 °C, time 100 min, solid/liquid ratio 1:10. The comprehensive characteriza...

Proanthocyanidins (PAs), also called condensed tannins, can protect plants against herbivores and are important quality components of many fruits. Two enzymes, leucoanthocyanidin reductase (LAR) and anthocyanidin reductase (ANR), can produce the flavan-3-ol monomers required for formation of PA polymers. We isolated and functionally characterized genes encoding both enzymes from grapevine (Viti...

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. ...

The interaction between four industrial wine yeast strains and grape juice chemical contaminants during alcoholic fermentation was studied. Industrial strains of Saccharomyces cerevisiae (AWRI 0838), S. cerevisiae mutant with low H2S production phenotype (AWRI 1640), interspecies hybrid of S. cerevisiae and S. kudriavzevii (AWRI 1539) and a hybrid of AWRI 1640 and AWRI 1539 (AWRI 1810) were exp...

The aim of this study was to evaluate whether the application two pre-harvest elicitors—methyl-jasmonate (MeJ) and benzothiadiazole (BTH)—to Monastrell grapes, at maturation stages, affected composition structure skin cell walls (SCWs) differing extents. This conducted in 2016–2017 on Vitis vinifera L. cv Monastrell. A water suspension MeJ BTH, a mixture both, applied veraison mid-ripening. ber...

Quercetin haze has been observed over the last few years in some aged Sangiovese wines. This problem could be due to an excess of quercetin wine. Leaf removal increases exposition clusters sunlight, which may enhance flavonol synthesis grapes. In this study, we evaluated dynamics related extractable flavonols grapes grown three usually defoliated Vitis vinifera (L.) cv. vineyards, whose wines s...

Ethanol metabolism is known to induce overwhelming production of reactive oxygen species (ROS) and also to cause associated immune dysfunction. Several interventional agents of plant origin, in particular fruits and vegetables have been used to counteract these alterations induced by ethanol. In this study, we investigated the efficacy of dietary feeding of skin and flesh of grapes (Vitis vinif...
