A novel virus-like sequence from grapevine was identified by Illumina sequencing. The complete genome is 7,551 nucleotides in length, with polyadenylation at the 3' end. Translation of the sequence revealed five open reading frames (ORFs). The genomic organization was most similar to those of vitiviruses. The polymerase (ORF1) and coat protein (ORF4) genes shared 31 to 49% nucleotide and 40 to ...

MIKC(C)-type MADS box genes encode transcription factors that play crucial roles in plant growth and development. Analysis of the grapevine (Vitis vinifera) genome revealed up to 38 MIKC(C)-type genes. We report here a complete analysis of this gene family regarding their phylogenetic relationships with homologous genes identified in other sequenced dicot genomes, their genome location, and gen...

Plasmopara viticola, the causal agent of grapevine downy mildew, is one of the most devastating grape pathogen in Europe and North America. Although phytochemicals are used to control pathogen infections, the appearance of resistant strains and the concern for possible adverse effects on environment and human health are increasing the search for alternative strategies. In the present investigat...

Fomitiporia mediterranea M. Fisch. (Fmed) is a basidiomycete first described in 2002, and was considered up to then as part of punctata (P. Karst) Murrill. This fungus can degrade lignocellulosic biomass, causing white rot leaving bleached fibrous host residues. In Europe Fmed the main grapevine wood (Esca) agent within Esca disease complex, which includes some most economically important Grape...

Grapevine rupestris stem pitting-associated virus (GRSPaV) is a worldwide-distributed pathogen in grapevines with a high genetic variability. Our study revealed differences in the complexity of GRSPaV population in a single host. A single-variant GRSPaV infection was detected from the SK30 grapevine plant. On the contrary, SK704 grapevine was infected by three different GRSPaV variants. Variant...

Whole-genome comparisons of Vitis vinifera subsp. sativa and V. vinifera subsp. sylvestris are expected to provide a better estimate of the valuable genetic diversity still present in grapevine, and help to reconstruct the evolutionary history of a major crop worldwide. To this aim, the increase of molecular marker density across the grapevine genome is fundamental. Here we describe the SNP dis...

A nonpathogenic strain of Rhizobium vitis ARK-1 was tested as a biological control agent for grapevine crown gall. When grapevine roots were soaked in a cell suspension of strain ARK-1 before planting in the field, the number of plants with tumors was reduced. The results from seven field trials from 2009 to 2012 were combined in a meta-analysis. The integrated relative risk after treatment wit...

Background and Aims. Grapevine is susceptible to several diseases requires a large use of fungicides. Sustainable alternatives must be safe for humans the environment also should not interfere with fermentation. The aim this study was implement rare sugar, tagatose, against powdery mildew downy assess possible side effects on Saccharomyces cerevisiae Methods Results. Tagatose evaluated suppress...

Grapevine, a crop of global economic importance, is annually affected by diseases that can compromise the quality and quantity harvest, producing large losses. Downy mildew caused Plasmopara viticola (Berk. & M.A. Curtis) Berl. de Toni one most important in vineyard. To fight this pathogen, winegrowers often rely on conventional chemical fungicides or copper-based formulations, whose use de...
