Grapevine phylloxera, Daktulosphaira vitifoliae (Fitch) (Hemiptera: Phylloxeridae) is a worldwide pest of Vitis species. It has forms that feed on leaves and roots. Root forms predominate on Vitis vinifera (L.) cultivars, while leaf forms predominate on Vitis species from its native American range. Recently, high densities of D. vitifoliae infestations in leaves of V. vinifera in Brazil, Peru, ...

Hybridization of introduced domesticates and closely related natives is well documented in annual crops. The widespread introduction of the domesticated grapevine, Vitis vinifera, into California where it overlaps with two native congenerics, with which it is interfertile, provides opportunity to investigate hybridization between woody perennials. Although geographically widespread, the introdu...

We report here that pink grape berries were obtained by a short insertion in the intron of the MybA1 gene, a gene that regulates grape berry color. Genetic variation was detected among the MybA1 genes from grapes cultivated worldwide. PCR analysis of the MybA1 gene demonstrated that the size of the MybA1 gene in the red allele differs among grapes. Oriental V. vinifera bearing pink berries has ...

Vitis vinifera L.is a traditional Asian herb widely used for different health problems. In thepresent research, the ethanolic and the aqueous extracts of Vitis vinifera L. leaves collected fromshrub, grown in Tunisia, were prepared and evaluated for the antileishmanial activity againstLeishmani ainfantum promastigotes. The inhibitory concentration 50 (IC50) was determined andthe results showed ...

The Aqueous Extract of Vitis vinifera leaves was investigated for its effect on some immunoglobulin in induced hyperthroidism rabbits . The equeous extract of leaves at does level of 100 mg ml showed significant increase ( p<0,05) on level of IgG and significant decrease ( p < 0.05) on level of IgA , IgM to normal level .

Here, we report the complete 5.3-Mb genome sequence of Xanthomonas campestris pv. viticola (CCRMXCV 80), which causes grapevine (Vitis vinifera L.) bacterial canker. Genome data will improve our understanding of the strain's comparative genomics and epidemiology, and help to further define plant protection and quarantine procedures.

A família Vitaceae é constituída por cerca de 15 gêneros e 850 espécies. Ocorre tanto em regiões temperadas como tropicais. Sendo conhecida ter o gênero introduzido cultivado no Brasil para a produção vinho, sucos frutas, podendo citar-se espécie V. Vinifera L. nesses usos. Vitis vinífera, nosso objeto estudo, forma comum uva, empregada na medica popular diferentes doenças cardiovasculares, pos...

The identification of archaeological charred grape seeds is a difficult task due to the alteration of the morphological seeds shape. In archaeobotanical studies, for the correct discrimination between Vitis vinifera subsp. sylvestris and Vitis vinifera subsp. vinifera grape seeds it is very important to understand the history and origin of the domesticated grapevine. In this work, different car...

BACKGROUND Genomic data release for the grapevine has increased exponentially in the last five years. The Vitis vinifera genome has been sequenced and Vitis EST, transcriptomic, proteomic, and metabolomic tools and data sets continue to be developed. The next critical challenge is to provide biological meaning to this tremendous amount of data by annotating genes and integrating them within the...
