Generic and species-specific detection of viruses belonging to an evolutionary distinct lineage within the Ampelovirus genus

Journal of Virological Methods, 2008
A nested RT-PCR was developed, that allows the generic detection of a subgroup of genetically related viruses with a distinct evolutionary history within the genus Ampelovirus. Members of this lineage are Grapevine leafroll associated virus-4, -5, -6, -9 and two isolates (GLRaV-De and GLRaV-Pr) that have been recently characterized and represent new ...

Air potato (Dioscorea bulbifera) plants displaying virus-like symptoms are co-infected with a novel potyvirus and a novel ampelovirus

Virus Genes, 2018
Air potato (Dioscorea bulbifera) plants being grown at the Florida Department of Agriculture and Consumer Services Division of Plant Industry Biological Control Laboratory II in Alachua County, Florida were observed exhibiting foliar mosaic symptoms characteristic of virus infection.

TAXONOMIC REVISION OF THE FAMILY CLOSTEROVIRIDAE WITH SPECIAL REFERENCE TO THE GRAPEVINE LEAFROLL-ASSOCIATED MEMBERS OF THE GENUS AMPELOVIRUS AND THE PUTATIVE SPECIES UNASSIGNED TO THE FAMILY

Journal of Plant Pathology, 2012
New insights into the genetic structure and variability of grapevine leafroll-associated viruses (GLRaVs) gained through worldwide efforts in the last decade or so, and the production and use of new sets of serological reagents, have provided the solid foundation on which the present revision of the taxonomic structure of the family Closteroviridae ...

Elimination of a new ampelovirus (GLRaV-Pr) and Grapevine rupestris stem pitting associated virus (GRSPaV) from two Vitis vinifera cultivars combining in vitro thermotherapy with shoot tip culture

Scientia Horticulturae, 2009
A new virus species designated as Grapevine leafroll associated virus-Pr (GLRaV-Pr), which is classified in a distinct phylogenetic group of the genus Ampelovirus (Closteroviridae), was recently characterized from Greek grapevine cultivars. Elimination studies of GLRaV-Pr were carried out in two grapevine cultivars, ‘Mantilaria’ and ‘Prevezaniko’, co ...

Transmission of Ampelovirus trivitis to grapevine cv. 'Plavac mali' by Planococcus ficus (Sign.)

60th Croatian and 20th International Symposium on Agriculture : Book of Abstracts
The species Ampelovirus trivitis, known as grapevine leafroll-associated virus 3 (GLRaV-3), is the most widespread virus identified in grapevine. GLRaV-3 is transmitted via grafting of infected plant material and by insect vectors. In the Croatian coastal region, one of the most common vectors is vine mealybug Planococcus ficus (Sign.). The aim of this

Acquisition and transmission of GLRAV-1 (Grapevine leafroll associated ampelovirus 1) by Planococcus citri (RISSO) (Hemiptera pseudococcidae)

2009
Grapevine leafroll disease occurs in all major grape-growing areas. Several Grapevine leafroll associated viruses (GLRaVs) have been shown to be transmitted by mealybugs. Nine mealybugs have been reported as vectors of GLRaV-3 although detailed characterization of GLRaV-1 vectors transmission is lacking. The presence of GLRaV-1 and Planococcus citri in

Μοριακός χαρακτηρισμός, εξελικτικές σχέσεις και ανίχνευση ιών της αμπέλου ενός διακριτού φυλογενετικού κλάδου του γένους Ampelovirus και εξυγίανση πολλαπλασιαστικού υλικού

2008
The evolutionary relationships of a group of genetically related ampeloviruses, namely GLRaV-4,-5,-6,-9 and two new isolates (GLRaV-Pr and GLRaV-De), were studied based on molecular variability, positive selection analysis and maximum likelihood (ML) phylogenies. Datasets corresponding to the N terminal HSP70h and full CP genes were analysed.

Transmission of Grapevine leaf roll-associated virus-1 and -3 (Ampelovirus) and Grapevine virus A (Vitivirus) by natural populations of soft scales and mealybugs in the North-eastern French vineyard

2009
Virus infectivity experiments were performed with three soft scale species, Parthenolecanium corni, Pa. persicae and Pulvinaria vitis, and one mealybug species, Heliococcus bohemicus, frequent in the north-eastern French vineyard. Insects were sampled on grapevines infected by leafroll viruses (GLRaV-1, -2, -3), either alone, or in combinations ...
