Complete genome sequences of two new variants of Grapevine rupestris stem pitting-associated virus and comparative analyses.
Grapevine rupestris stem pitting-associated virus (GRSPaV), a member of the genus Foveavirus within the family Flexiviridae, is the putative causal agent of the disease Rupestris stem pitting (RSP) of grapevines. GRSPaV comprises a family of variants whose pathological characteristics have not been determined. Recently, many of the indicator "St George" plants (Vitis rupestris) used throughout ...
متن کاملSequence diversity, population genetics and potential recombination events in grapevine rupestris stem pitting-associated virus in Pacific North-West vineyards.
Grapevine rupestris stem pitting-associated virus (GRSPaV; genus Foveavirus, family Flexiviridae) is present in many grape-growing regions of the world. A total of 84 full-length coat protein (CP) sequences and 57 sequences representing the helicase-encoding region (HR) of the RNA-dependent RNA polymerase were obtained from wine grape cultivars grown in the Pacific North-West (PNW) of the Unite...
متن کاملElimination of Grapevine leafroll associated virus-3, Grapevine rupestris stem pitting associated virus and Grapevine virus A from a Tunisian Cultivar by Somatic Embryogenesis and Characterization of the Somaclones Using Ampelographic Descriptors
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...
متن کاملComplete Genomic Characterization of Plum bark necrosis stem pitting–associated virus Infecting Sweet Cherry in China
Plum bark necrosis stem pitting-associated virus (PBNSPaV) causes the plum bark necrosis stem pitting-associated disease. We obtained the complete genome of a PBNSPaV isolate (PBNSPaV-TA) using small RNA deep sequencing followed by overlapping RT-PCR. To our knowledge, this is the first report of a completed genome of PBNSPaV identified from cherry trees.
متن کاملAnalysis of Grapevine rupestris stem pitting-associated virus in Slovakia Reveals Differences in Intra-Host Population Diversity and Naturally Occurring Recombination Events
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...
