Bud mite, blister mite ( Colomerus vitis Pagenstecher), and rust mite ( Calepitrimerus vitis Nalepa) (Acari: Eriophyoidae) are recognized grapevine pests. Much of the biology and ecology of these pests is poorly understood. We used two types of molecular markers to gain further insight into the breeding biology and population structure of these mites, using individuals collected from sites arou...

The transcription factor VaCBF2, which interacts with C-repeat/DRE and its promoter, was isolated from Vitis amurensis. The VaCBF2 amino acid sequence contained a conserved AP2 domain of 56 amino acids and a potential nuclear localization sequence. The sequence of VaCBF2 showed a high level of homology with other CBF2 family members. Phylogenetic analysis showed that the amino acid sequences ma...

In vitro preservation of the “Kober 5BB” rootstock (Vitis berlandieri ˆ Vitis riparia) was assessed with the encapsulation technique and slow growth storage. Shoot tips and nodal segments excised from in vitro cultures were encapsulated in calcium-alginate beads. A 30 min ion exchange time proved optimal for forming proper beads. The encapsulated and naked explants were stored at 4 ̋C in the da...

Koshu is a grape cultivar native to Japan and is one of the country's most important cultivars for wine making. Koshu and other oriental grape cultivars are widely believed to belong to the European domesticated grape species Vitis vinifera. To verify the domesticated origin of Koshu and four other cultivars widely grown in China and Japan, we genotyped 48 ancestry informative single nucleotide...

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...

Crown gall tumors collected from naturally infected plants of 7 grapevine varieties were analysed for the presence of opines. Eighty-five of the tested 90 samples contained known Agrobacterium vitis-induced opines. Octopine was the most common, it was found in 50 samples. Twentyeight crown galls contained nopaline and 8 were vitopine positive. There was only one tumor that contained two opines,...

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 ...
