Grapevine biotechnology is one of the most promising developments in the global wine industry, which is increasingly faced with conflicting demands from markets, consumers and environmentalists. In the grapevine industries, this technology and its supporting disciplines entail the establishment of stress tolerant and disease resistant varieties of Vitis vinifera, with increased productivity, ef...

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. Using an approach developed for the analysis of human and mammalian genomes, which combines high-throughput sequencing, arra...

The leaf surface is the first barrier of grapevine plants towards various environmental stressors causing damage in vineyards. For this reason, identification of leaf surface metabolites in grapevine and their putative role in plant–environment interactions is important for viticulture. In this study, the leaf surface components of 16 grapevine plants (Vitis vinifera) growing in an experimental...

The analysis of the first plant genomes provided unexpected evidence for genome duplication events in species that had previously been considered as true diploids on the basis of their genetics. These polyploidization events may have had important consequences in plant evolution, in particular for species radiation and adaptation and for the modulation of functional capacities. Here we report a...

Prospecting of local grapevine (Vitis vinifera L.) germplasm revealed that Tunisia possesses a rich patrimony which presents diversified organoleptic characteristics. However, viral diseases seriously affect all local grapevine cultivars which risk a complete extinction. Sanitation programs need to be established to preserve and exploit, as a gene pool, the Tunisian vineyards areas. The presenc...

Introduction The presence of double stranded RNA (dsRNA) in virus-infected tissue has been well documented by Morris and Dodds (4), Dodds and Bar-Joseph (2). The analysis of dsRNA proved to be useful for determining the virus-free status of propagation material after sanitation treatments. Isolated directly from grapevine, dsRNA is also a good source of viral RNA for synthesizing and cloning cD...

the incidence of grapevine virus a (gva) is reported from almost all of the major grapevine growing regions in iran. grapevine is vegetatively propagated by rooting of cuttings or grafting. in such plants, viral diseases are transmitted from stock plants to the progeny. therefore, the control of grapevine viruses can be achieved primarily through production of healthy stock plants. in the p...
