Correlation between antioxidant and anticancer activity and phenolic profile of new Apulian table grape genotypes ( L.).

Grapes represent a significant source of phenolic compounds known for their health-promoting properties, such as antioxidant capacity on normal cells and prooxidant activity on tumor cells. The genotype highly affects the polyphenolic composition in grapes and, consequently, the nutritional quality of berries. This work aimed to characterize the phenolic composition, the antioxidant, and anticancer activity of grape skin extracts (GSEs) of nine new table grape genotypes selected from a breeding program to obtain new cultivars of seedless table grapes, well adapted to the climatic change and with higher nutraceutical properties.

Use of Artificial Neural Networks and NIR Spectroscopy for Non-Destructive Grape Texture Prediction.

In this article, a combination of non-destructive NIR spectroscopy and machine learning techniques was applied to predict the texture parameters and the total soluble solids content (TSS) in intact berries. The multivariate models obtained by building artificial neural networks (ANNs) and applying partial least squares (PLS) regressions showed a better prediction ability after the elimination of uninformative spectral ranges. A very good prediction was obtained for TSS and springiness (R 0.

Native Vineyard Non- Yeasts Used for Biological Control of in Stored Table Grape.

Postharvest spoilage fungi, such as , are considered the main cause of losses of fresh fruit quality and vegetables during storage, distribution, and consumption. The current control strategy is the use of SO generator pads whose application is now largely under observation. A high quantity of SO can be deleterious for fresh fruits and vegetables and it is not allowed in organic agriculture.

Color Stabilization of Apulian Red Wines through the Sequential Inoculation of and .

Mixed fermentation using and has gained attention in recent years due to their ability to modulate the qualitative parameters of enological interest, such as the color intensity and stability of wine. In this study, three of the most important red Apulian varieties were fermented through two pure inoculations of strains or the sequential inoculation of after 48 h from . The evolution of anthocyanin profiles and chromatic characteristics were determined in the produced wines at draining off and after 18 months of bottle aging in order to assess the impact of the different fermentation protocols on the potential color stabilization and shelf-life.

NIR Analysis of Intact Grape Berries: Chemical and Physical Properties Prediction Using Multivariate Analysis.

Texture characteristics are valuable parameters in the perceived quality and overall acceptability of fresh fruit. The characterization of grape texture attributes, such as firmness and crunchiness, is usually performed by sensory analysis or instrumental texture analysis. Both methodologies are destructive.

Unraveling the Deep Genetic Architecture for Seedlessness in Grapevine and the Development and Validation of a New Set of Markers for VviAGL11-Based Gene-Assisted Selection.

Seedless inheritance has been considered a quasi-monogenic trait based on the VvAGL11 gene. An intragenic simple sequence repeat (SSR) marker, p3_VvAGL11, is currently used to opportunely discard seeded progeny, which represents up to 50% of seedlings to be established in the field. However, the rate of false positives remains significant, and this lack of accuracy might be due to a more complex genetic architecture, some intrinsic flaws of p3_VvAGL11, or potential recombination events between p3_VvAGL11 and the causal SNP located in the coding region.

FT-NIR Analysis of Intact Table Grape Berries to Understand Consumer Preference Driving Factors.

Fourier-transform near infrared spectroscopy (FT-NIR) is a technique used in the compositional and sensory analysis of foodstuffs. In this work, we have measured the main maturity parameters for grape (sugars and acids) using hundreds of intact berry samples to build models for the prediction of these parameters from berries of two very different varieties: "Victoria" and "Autumn Royal". Together with the chemical composition in terms of sugar and acidic content, we have carried out a sensory analysis on single berries.

Inter-varietal structural variation in grapevine genomes.

Grapevine (Vitis vinifera L.) is one of the world's most important crop plants, which is of large economic value for fruit and wine production. There is much interest in identifying genomic variations and their functional effects on inter-varietal, phenotypic differences.

Ampelometric Leaf Trait and SSR Loci Selection for a Multivariate Statistical Approach in Vitis vinifera L. Biodiversity Management.

High estimated heritability values were recently revealed for mature leaf traits in grape (Vitis vinifera L.), thus redeeming ampelography in the era of molecular markers. The "Organisation Internationale de la Vigne et du Vin (OIV)" set a list of hundreds of descriptors for grapevine in order to standardize ampelographic and ampelometric scores.

Morphological variability in leaves and molecular characterization of novel table grape candidate cultivars (Vitis vinifera L.).

The present work report the characterization of twenty-one table grapes candidate cultivars plus five registered ones included as reference, by means of 47 ampelographic traits, 23 ampelometric measurements and six microsatellite loci. The final goal of the research was to analyse the possibility of reducing the number of morphological and molecular tools required for a precise and effective description of a grape genotype or cultivar. This would be of great help for future biodiversity description on a larger sample of more than 300 table grapes accessions today grown at the 'Consiglio per la Ricerca e la sperimentazione in Agricoltura (C.

Validation assay of p3_VvAGL11 marker in a wide range of genetic background for early selection of stenospermocarpy in Vitis vinifera L.

DNA markers technology, derived from research in molecular biology and genomics, offers great promise for plant breeding, allowing the "molecular breeding" via marker-assisted selection. Grapevine genomic resources allowed, in recent years, the characterization at molecular level of genes involved in interesting phenotypes such as stenospermocarpic seedlessness, a trait really appreciated by consumers. Recent studies in table grapes revealed that the VvAGL11 gene, member of the D-lineage MADS-box family, controls the ovule identity, and thus potentially playing an important role in stenospermocarpy.

Sangiovese and its offspring in southern Italy.

This paper demonstrates the importance of different approaches such as ampelography, historical researches, and molecular analysis to reveal direct parent-child relationship. The aim of this paper was to highlight the degree of relationship to five varieties spread in southern Italy, through ampelographic and molecular characterization: Sangiovese, Mantonico di Bianco, Gaglioppo di Cirò, Mantonicone, and Nerello Mascalese. Molecular characterization was carried out through 52 SSR molecular markers, showing that Sangiovese and Mantonico di Bianco are the parents of Gaglioppo di Cirò, Mantonicone, and Nerello Mascalese.

Evidences for an alternative genealogy of 'Sangiovese'.

Two different hypothesis for the parentage of 'Sangiovese', the most important and widespread Italian winegrape, have been proposed by some previous studies. We screened our grapevine collection, mostly comprising south Italian cultivars collected to preserve biodiversity, to asses kinships. Surprisingly we found two previously unreported candidate parents for 'Sangiovese'.

HPLC-DAD-ESI-MS analysis of flavonoid compounds in 5 seedless table grapes grown in Apulian Region.

Unlabelled: Flavonoids present in skin extracts of red seedless table grape varieties Summer Royal, Autumn Royal, and Crimson, and white seedless varieties Carati and Thompson were analyzed by HPLC-DAD-MS, in 3 y of study (2006 to 2008). The anthocyanins, delphinidin-3-O-glucoside, cyanidin-3-O-glucoside, petunidin-3-O-glucoside (with their corresponding p-coumaroyl derivatives), peonidin-3-O-glucoside, and malvidin-3-O-glucoside (with their corresponding acetyl, caffeoyl, and p-coumaroyl derivatives) were found. In addition the flavonols quercetin-3-O-glucuronide, quercetin-3-O-rutinoside, quercetin-3-O-glucoside, kaempferol-3-O-glucoside, kaempferol-3-O-galactoside, and the flavan-3-ols procyanidin B1, procyanidin B2, and catechin were also detected.
