Metagenomic Next-Generation Sequencing of Viruses Infecting Grapevines

2015
Next-generation sequencing (NGS) technologies, for the first time, provide a truly "complete" representation of the viral (and other) pathogens present in a host organism. This is achieved in an unbiased way, and without any prior biological or molecular knowledge of these pathogen(s).

Grapevine Leafroll Disease and Associated Viruses: A Unique Pathosystem

Annual Review of Phytopathology, 2015
Grapevine leafroll is the most complex and intriguing viral disease of grapevine (Vitis spp.). Several monopartite closteroviruses (family Closteroviridae) from grapevines have been molecularly characterized, yet their role in disease etiology is not completely resolved. Hence, these viruses are currently designated under the umbrella term of Grapevine

Other Grapevine Viruses of Lesser Economic Importance

2017
Symptomatic vines infected by Alfalfa mosaic virus (AMV), Grapevine angular mosaic virus (GAMV), Grapevine line pattern virus (GLPV), Raspberry bushy dwarf virus (RBDV), and Grapevine Roditis leaf discoloration-associated virus (GRLDaV) have been reported from different European countries, whereas infections by Grapevine berry inner necrosis virus ...

Grapevine Viruses' Detection and Sanitary Selection in Grapevine Germplasm of Calabria (Southern Italy)

Journal of Phytopathology, 2014
AbstractA survey of grapevine viruses present in the region of Calabria (southern Italy) was carried out, and the sanitary selection was conducted on various indigenous varieties. Serological (ELISA) and molecular (multiplex RT‐PCR) tests were used to detect the viruses included in the Italian certification programme: Arabis mosaic virus (ArMV ...

Viruses and virus diseases of grapevine in Lebanon

EPPO Bulletin, 1996
Grapevines were surveyed for the presence of virus and virus‐like diseases in the main viticultural areas of Lebanon (Bekaa valley, Mount Lebanon, South and North Lebanon). Symptoms of rugose wood were observed in vines ofall cultivars and areas surveyed, whereas leafroll was observed only in some vineyards of the Bekaa valley and, to a lesser extent ...

Viruses and virus diseases of grapevine in Palestine

EPPO Bulletin, 1998
Surveys were carried out in vineyards in the main grapevine‐growing areas of Palestine (Hebron, Bethlehem, Gaza, Jerusalem, Ramallah, Jenin, Jericho and Nablus) to assess the presence and incidence of virus and virus‐like diseases. Leafroll symptoms were observed in Bethlehem, Ramallah and Jerusalem in native and imported cultivars, with higher rates ...

Viruses and virus diseases of grapevine in Tunisia

EPPO Bulletin, 1998
Mature canes were collected from vines in the main grapevine‐growing areas in Tunisia (Cape Bon, Bizerte, Ben Arous), from commercial vineyards and mother‐plant plots, to assess the presence of virus and virus‐like diseases. Biological (mechanical transmission onto herbaceous hosts and grafting onto indicator woody plants) and serological detection ...

Investigation of suspected grapevine viruses in South Australia

Australian Journal of Agricultural Research, 1967
Evidence is presented that a strain of grapevine yellow mosaic virus is present in South Australia, but its incidence is very low and a nematode vector has not been found in affected vineyards. The "dying arm" disorder of vines is not due to infection by fanleaf virus as previously suspected, and typical fanleaf virus has not been found in the State. A

Grapevine Viruses in the Atacama Region of Chile

Journal of Phytopathology, 2011
AbstractVineyards in the Atacama region in Chile were surveyed from 2007 to 2009 for the presence of viruses. This region is an important area of table grape production, supplying international markets with its fruits in the off season of the Northern Hemisphere. Reverse transcription‐polymerase chain reaction (RT‐PCR) assay was used to detect the most

Complete Nucleotide Sequence of the RNA-2 of Grapevine Deformation and Grapevine Anatolian Ringspot Viruses

Virus Genes, 2005
The nucleotide sequence of RNA-2 of Grapevine Anatolian ringspot virus (GARSV) and Grapevine deformation virus (GDefV), two recently described nepoviruses, has been determined. These RNAs are 3753 nt (GDefV) and 4607 nt (GARSV) in size and contain a single open reading frame encoding a polyprotein of 122 kDa (GDefV) and 150 kDa (GARSV).
