Isolate Description

Location: the United States of America.

Host of Isolate and Habitat Details
Source of isolate: Vitis vinifera.

Natural hosts and symptoms Vitis vinifera — in intolerant cultivars, delayed bud opening, reduced vigour and yield, swelling of trunk and, sometimes, thick and rough spongy bark; woody cylinder of rootstock and/or scion pitted and/or grooved. Some cultivars and rootstocks are tolerant and produce no symptoms.

Reference to Isolation Report

Classification

This is a description of a plant virus at the species level.

ICTVdB Virus Code: 00.017.0.71.029. Virus accession number: 17091029. Obsolete virus code: 17.0.1.T.U.03; superceded accession number: 1701tu03.

Name, Synonyms and Lineage

ICTV approved acronym: GCBaV. Virus is a tentative member of the genus 00.017.0.01. Closterovirus in the family 00.017. Closteroviridae.

Virion Properties

Morphology

Virions consist of a capsid. Virus capsid is not enveloped. Capsid/nucleocapsid is elongated with helical symmetry. The capsid is filamentous, flexuous with a length of 1400-2000 nm.

Nucleic Acid

The genome is monopartite. Only one particle size of linear, positive-sense, single-stranded RNA is recovered.

Proteins

The viral genome encodes structural proteins and non-structural proteins.

Lipids

Lipids are not reported.

Biological Properties

Natural Host

Domain
Viral hosts belong to the Domain Eucarya.

Domain Eucarya
Kingdom Plantae.

Kingdom Plantae
Phylum Magnoliophyta (Angiosperms, Class Magnoliopsida (Dicotyledonae).

Transmission and Vector Relationships

Virus is transmitted by a vector. Virus is not transmitted by mechanical inoculation; transmitted by grafting.

Vector Transmission:
Virus is transmitted by arthropods, by insects of the order Hemiptera, family Psyllidae. Virus is not transmitted by Planococcus ficus.

Experimental Hosts and Symptoms

Under experimental conditions susceptibility to infection by virus is found in few families. Susceptible host species are found in the Family Vitidaceae. The following species were susceptible to experimental virus infection: Vitis berlandieri x Conderc 1613, Vitis berlandieri x V. riparia, Vitis rupestris, Vitis vinifera.

Diagnostic Hosts

Diagnostic host species and symptoms:

Vitis berlandieri x Conderc 1613 (LN33) — swelling of basal internodes due to proliferation of secondary phloem, and stem grooving.

Vitis berlandieri x V. riparia (Kober SBB) — symptomless.

Vitis rupestris — stem grooving.

Maintenance and Propagation Hosts

Most commonly used maintenance and propagation host species are Vitis vinifera (LN33) and V. rupestris.

Geographical Distribution

The virus spreads in Africa.
