Host of Isolate and Habitat Details Natural hosts and symptoms

Five viruses, designated grapevine leafroll-associated 1,2,3,4 and 5 closteroviruses have been associated with grapevine leafroll disease (Candresse and Martelli, 1995), but none has been fully characterized.

Vitis vinifera — rolling and discoloration of leaves (reddish-purple in red-fruited, and yellowish in white-fruited cultivars), especially conspicuous in late summer and early autumn in intolerant cultivars. Symptomless infection in some American Vitis ssp. and hybrids.

Classification

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

ICTVdB Virus Code: 00.017.0.03.003. Virus accession number: 17003003. Obsolete virus code: 00.017.0.01.009.; 17.0.1.T.U.04; superceded accession number: 17001009; 1701tu04.
NCBI Taxon Identifier NCBI Taxonomy ID: 55951.

Name, Synonyms and Lineage

ICTV approved acronym: GLRaV-3. Virus is the type of the genus 00.017.0.03. Ampelovirus 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 1800-2200 nm.

Nucleic Acid

The genome is monopartite. Only one particle size of linear, positive-sense, single-stranded RNA is recovered, is partially sequenced. Sequence has the accession number

[X75448] Em(40)_vi:GVBMPCP Gb(84)_vi:GVBMPCP Grapevine virus B genomic RNA for MP and CP genes. 5/94 2,161bp.
[U22158] Gb(89)_vi:Glu22158 Grapevine leafroll associated virus type III p20 protein, partial cds. 3/95 1,012bp.
[U22170] Em(43)_vi:Gl22170 Gb(89)_vi:Glu22170 Grapevine leafroll associated virus RNA6 gene, partial cds. 5/95 965bp.

GenBank records for nucleotide sequences; complete genome sequences.

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 transmitted by grafting.

Vector Transmission:
Virus is transmitted by arthropods, by insects of the order Hemiptera; Pseudococcus longispinus, Planococcus ficus (GLRaV-3).

Experimental Hosts and Symptoms

Susceptible host species are found in the Family Vitidaceae. The following species were susceptible to experimental virus infection: Vitis vinifera.

Diagnostic Hosts

Diagnostic host species and symptoms:
Vitis vinifera cvs Cabernet, Pinot Noir, Mission, Gamay — leafrolling and discoloration.

Geographical Distribution

The virus is probably distributed worldwide.
