Infectious cDNA clones of two grapevine viruses

Archives of Virology, 2000
Full-length cDNA copies of the genomes of Grapevine virus A (GVA) and Grapevine virus B (GVB) under the control of bacteriophage T7 promoter have been synthesized, which were refractory to cloning in Escherichia coli. However, both transcribed cDNAs were infectious when mechanically inoculated to Nicotiana plants.

Control of Viruses Infecting Grapevine

2015
Grapevine is a high value vegetatively propagated fruit crop that suffers from numerous viruses, including some that seriously affect the profitability of vineyards. Nowadays, 64 viruses belonging to different genera and families have been reported in grapevines and new virus species will likely be described in the future.

Macroarray detection of grapevine leafroll-associated viruses

Journal of Virological Methods, 2012
Grapevine leafroll-associated viruses (GLRaVs) are an emerging group of viruses that represent a significant threat to the global productivity and sustainability of the grapevine industry. Their control is achieved through the identification and elimination of infected vines, and the use of planting material derived from virus-tested, certified stocks.

Grapevine fleck virus-like viruses in Vitis

Archives of Virology, 2000
Two sets of degenerate primers for the specific amplification of 572-575 nt and 386 nt segments of the methyltransferase and RNA- dependent RNA polymerase cistrons of members of the genera Tymovirus and Marafivirus and of the unassigned virus Grapevine fleck virus (GFkV) were designed on the basis of available sequences.

Detection of Grapevine Viruses in Poland

Journal of Phytopathology, 2013
AbstractDuring a 3‐year study, grapevines from 23 vineyards in Poland were surveyed for virus diseases and tested to determine the prevalence of the most economically important viruses by RT‐PCR. The rate of positive samples was 2.2% for grapevine leafroll‐associated virus 1 (GLRaV‐1), 1.9% for grapevine leafroll‐associated virus 2 (GLRaV‐2), 1.5 ...

Grapevine fleck and similar viruses

2017
Grapevine fleck virus (GFkV), grapevine red globe virus (GRGV), grapevine rupestris vein feathering virus (GRVFV), grapevine asteroid mosaic-associated virus (GAMaV), and grapevine Syrah virus 1 (GSyV-1) are a group of evolutionarily related viruses with similar morphological, physicochemical, and molecular properties.

Vector Transmission of Grapevine Leafroll-Associated Viruses

2017
The ampeloviruses causing grapevine leafroll disease are transmitted by mealybug and soft scale insect vectors. Vector transmission of virus species in this complex occurs in a semi-persistent manner, with no current evidence of a strict vector-virus species specificity.

[Grapevine viruses in Tunisia].

Archives de l'Institut Pasteur de Tunis, 2004
Tunisian grapevine culture is affected by many viruses caused by some phytovirus belonging to nepovirus, closterovirus and trichovirus groups. The present work deal with the economically important viroses identified in tunisian grapevines. We present here the development methods to detect these viruses in propagating material.

Ectoparasitic Nematode Vectors of Grapevine Viruses

2017
Nematodes of the genera Longidorus, Paralongidorus, and Xiphinema in the family Longidoridae can parasitize grapevine roots. These ectoparasitic soil-borne nematodes live in proximity to the rhizosphere and use a stylet to feed on root cells. During the feeding process, some nematodes are able to acquire and transmit nepoviruses, the causal agents of ...

Sequence Analysis of the 3′ end of Three Grapevine Fleck Virus-like Viruses from Grapevine

Virus Genes, 2003
The 3' end of the genome of three Grapevine fleck virus-like viruses, i.e. Grapevine redglobe virus (GRGV), Grapevine asteroid mosaic-associated virus (GAMaV), and an unidentified virus from a Greek grapevine (accession GR8-19) was amplified from reverse transcribed total nucleic acid extracts from infected grapevine tissues and sequenced. The analysed
