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 ...

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.

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 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 ...

[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.

Viruses and virus diseases of grapevine in Egypt

EPPO Bulletin, 2004
Surveys for virus and virus‐like diseases were carried out in commercial vineyards of the main grapevine‐growing areas of Egypt along the river Nile and in recently reclaimed desert lands. The only symptoms observed and identified with reasonable confidence in the field were those of leafroll disease in red‐berried cultivars.

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 ...

Microarray immunoassay for the detection of grapevine and tree fruit viruses

Journal of Virological Methods, 2009
Development and application of DNA microarrays for plant disease diagnosis has to date been limited, and for antibody arrays even more so. In this work, an antibody microarray procedure was developed and its usefulness for the detection of plant viruses demonstrated.

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).
