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...

A novel virus-like sequence from grapevine was identified by Illumina sequencing. The genomic organization was most similar to that of members of the genus Fabavirus Polyproteins RNA-1 and RNA-2 of the virus tentatively named grapevine fabavirus (GFabV) shared 34 to 23% sequence identities with Broad bean wilt virus 2 (BBWV2), respectively. GFabV was successfully graft transmitted to Vitis vini...

Here, we report the genome sequence of grapevine virus T (GVT), a novel single-stranded RNA virus identified from a transcriptome of grapevine. The genome of GVT is 8,701 nucleotides in length and encodes five open reading frames. GVT is a putative member of the genus Foveavirus in the family Betaflexiviridae.

Here, we report the genome sequence of grapevine virus K (GVK), a novel single-stranded RNA virus identified from a transcriptome of grapevine. The genome of GVK is 7,476 nucleotides in length and encodes 5 open reading frames. GVK is a putative member of the genus Vitivirus in the family Betaflexiviridae.

Résumé — Détection par Elisa du virus de la marbrure de la vigne (GFkV = grapevine fleck virus). L’association du Grapevine fleck virus (GFkV) avec les symptômes de la marbrure de la vigne a été établie par Elisa. La détection par Elisa du GFkV dans les plants de vigne n’est pas possible pendant la totalité du cycle végétatif : dans nos conditions, en Alsace, les mois de juin et juillet c...

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...
