Developing a Genetic Transformation Protocol for American Grapes (Vitis X Lambruscana) and Transforming Vitis to Produce Parthenocarpic Fruits
The main goal of this research was to transform Vitis. x labruscana L. H. Bailey ('Fredonia' and 'Niagara') and a seedling of a complex hybrid of 'Melody' (='Melody Seedling') with the gene Agl-iaaM (Agl = flower specific and developing fruit specific promoter; iaaM = indoleacetamide monooxygenase …

Cancer Chemoprevention by Vaccinium and Vitis Extracts
… that specific fractions of both Vaccinium and Vitis species possess considerable anticancer activity. The exact compounds responsible for these activities and their specific mechanisms of action warrant further investigation as potential cancer chemopreventative agents for humans.

Efficacy of the biological control agent Rhizobium vitis ARK-1 against tumorigenic Rhizobium vitis, the causal agent of grapevine crown gall
… by the tumorigenic bacterium Rhizobium vitis. Crown gall results in a gradual decline in yield and vine vigor, then the complete collapse of the vine. R. vitis ARK-1, an antagonistic and non-tumorigenic strain, has been shown to inhibit gall formation when equal cell concentrations of …

Genetic diversity and population structure of Vaccinium vitis-idaea
… in wild populations of lingonberry (Vaccinium vitis-idaea). This survey included 195 individual samples across 15 populations, assayed at 18 nuclear microsatellite loci to reveal the sexual and asexual reproductive strategies of this species. Five of the fifteen populations were found to …

PALISSAGE: AN ALTERNATIVE TO MECHANICAL HEDGING IN VITIS VINIFERA VINEYARDS
… conducted on “Riesling” and “Cabernet Franc” (Vitis vinifera L.) in commercial vineyards in King Ferry (Finger Lakes region, New York) and Cutchogue (North fork of Long Island, New York), respectively. The trials at the two sites were randomized complete block designs, each with four …

A comparative analysis of the metabolomes of different berry tissues between Vitis vinifera and wild American Vitis species, supported by a computer-assisted identification strategy
Grape (Vitis vinifera L.) is among the most cultivated plants in the world. Its origin traces back to the Neolithic era, when the first human communities started to domesticate wild Vitis sylvestris L. grapes to produce wines. Domestication modified Vitis vinifera to assume characteristics imparted …

Postharvest Storage and Nutraceutical Evaluation of Muscadine Grapes (Vitis rotundifolia Michx.)
<p>A major limiting factor in muscadine grape (Vitis rotundifolia Michx.) commercialization is deterioration during storage. One solution for extending market seasons and preventing market saturation for fresh muscadines could be the release of new cultivars with improved postharvest storability. …

Characterisation of the Auxin Signalling Pathway in Vitis vinifera L. cv. Shiraz
… receptor family members were identified in Vitis vinifera sp. The conserved domains were analysed in each group of proteins and their presence or absence related to possible function. Phylogenetic trees demonstrated the relationship of the Vvi genes with apple, Arabidopsis, poplar, and …

Effect of vineyard management of Cabernet Sauvignon (Vitis vinifera L.) grape glycosides
… crop levels from mature Cabernet Sauvignon (<i>Vitis vinifera</i> L.) vines grown in eastern Virginia were evaluated for their influence on grape glycosides, expressed as red-free glycosyl glucose (GG). Crop levels averaged 3.2, 5.1, and 6.4 kg/vine resulting in leaf area to fruit weight ratios …

Effects of Capture and Return on Chardonnay (Vitis vinifera L.) Fermentation Volatiles
Effectiveness of a capture and return system for the partial retention of fermentation volatiles, as a means of improving white wine quality, was evaluated. Twenty-three aroma-active volatiles including ethyl esters, acetate esters, fusel alcohols, and fatty acids, were quantified using head-space …

Adaptación de variedades blancas de vid (vitis vinifera l.) En Castilla-La Mancha
En una región vitícola como Castilla-La Mancha, en la que predomina una variedad blanca autóctona como Airén y con excedentes estructurales de vino, resulta muy interesante realizar estudios previos tendentes a la diversificación varietal del viñedo. Además de introducir variedades tintas de …

Quantitative Trait Loci (Qtl) Analysis Of Sulfur Sensitivity In Vitis Aestivalis-Derived 'Norton'
… modification in the Eurasian grape species Vitis vinifera with little to no phytotoxicity. However, genetic factors contributing to sulfur sensitivity, characterized by vegetative necrosis and defoliation, remain undefined in North American grape species and their commercial hybrids. A …

Relationships between berry sensory assessment and wine quality in Vitis vinifera L. Shiraz
Berry sensory assessment (BSA) is a technique that can help grapegrowers and winemakers make decisions about harvest date and grape product allocation. BSA as a structured technique has been used by grapegrowers, winemakers and researchers for the last thirteen years. However the number of studies …

Drivers of reproductive variability in Vaccinium cespitosum and vaccinium vitis-idaea in northeastern Minnesota
… in Vaccinium cespitosum and Vaccinium vitis-idaea (Ericaceae), and how the history of land management affects reproductive variability in V. cespitosum. Vaccinium populations with a history of land management are expected to have higher reproductive potential than populations that have …

Investigating peduncle colour evolution and chemistry during ripening in Vitis vinifera L. cv Shiraz
… of the grape stem (peduncle and rachis) in Vitis vinifera L. cv Shiraz evolve in terms of their colour and chemical attributes during the ripening period and is compared to the prototypical berry ripeness parameters (⁰Brix, pH, TA, etc) over three seasons. The grape peduncles turned from …
