Classification

This is a description of a plant virus at the species level with data on all virus properties from morphology to genome, replication, antigenicity and biological properties.

ICTVdB Virus Code: 00.015.0.01.011. Virus accession number: 15001011. Obsolete virus code: 15.0.1.0.011; superceded accession number: 15010011.
NCBI Taxon Identifier NCBI Taxonomy ID: 47903.

Name, Synonyms and Lineage

Synonym(s): yellow vein banding virus, chiloensis vein banding virus, Eastern veinbanding virus. ICTV approved acronym: SVBV. Virus is a tentative member of the genus 00.015.0.01. Caulimovirus in the family 00.015. Caulimoviridae.

Virion Properties

Morphology

Virions consist of a capsid. Virus capsid is not enveloped, round with icosahedral symmetry. The isometric capsid has a diameter of 43 nm (~ 4nm). The capsid shells of virions are composed of multiple layers. Capsids appear round.

Electron microscopic preparation and references: Virus preparation contains few virions. Purification, 1% formaldehyde treatment, stain with UA. For ISEM use cauliflower mosaic virus antiserum to trap virions. Reference for electron microscopic methods: Morris et al. (1980).

Physicochemical and Physical Properties

There are 1 sedimenting component(s) found in purified preparations. The sedimentation coefficient is 200 S20w (~10).

Nucleic Acid

The genome is not segmented and contains a single molecule of circular. The genome is -RT. The genome is double-stranded DNA. The complete genome is 7800 nucleotides long. Genome is sequenced, but only an estimate is available, complete sequence is 7800 nucleotides long.

GenBank records for nucleotide sequences; complete genome sequences.

Proteins

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

Non-Structural Proteins: The virus codes for an RNA-dependent DNA polymerase.

Lipids

Lipids are not reported.

Transcription: The virus codes for 7 ORF(s).

Translation: The genome replicates in in cytoplasmic inclusions. Replication involves a reverse transcription step.

Antigenicity

The virus is serologically related to cauliflower mosaic virus. The virus does not show serological relationships to carnation etched ring virus.

The strawberry vein-banding virus genome has no significant homology in hybridization tests with that of cauliflower mosaic virus.

Biological Properties

Natural Host

Domain
Viral hosts belong to the Domain Eucarya.

Domain Eucarya
Kingdom Plantae.

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

Class Magnoliopsida (Dicotyledonae)
Subclass ROSIDAE.

Severity and Occurrence of Disease

Host: Signs and symptoms persist (but symptoms fluctuate in severity).

Transmission and Vector Relationships

Virus is transmitted by a vector. Virus is not transmitted by mechanical inoculation; transmitted by grafting; not transmitted by contact between hosts; not transmitted by seeds; not transmitted by pollen.

Vector Transmission:
Virus is transmitted by arthropods, by insects of the order Hemiptera, family Aphididae; Chaetosiphon jacobi, C. fragaraefolii, C. thomasi. Virus is transmitted in a semi-persistent manner; does not replicate in the vector; not transmitted congenitally to the progeny of the vector.

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 Rosaceae. The following species were susceptible to experimental virus infection: Fragaria chiloensis, Fragaria vesca, Fragaria virginiana, Fragaria x ananassa, Sanguisorba minor.

Diagnostic Hosts

Diagnostic host species and symptoms:

Fragaria vesca, F. virginiana, F. chiloensis and F. x ananassa — yellow vein banding, discontinuous banding, streaking and spotting of older leaves, twisting of leaflets.

Maintenance and Propagation Hosts

Most commonly used maintenance and propagation host species are Most species and clones of Fragaria vesca, F. virginiana, F. chiloensis and F. x ananassa.

Assay Hosts

Host: Assay hosts (for Local lesions or Whole plants):
Fragaria vesca (W), F. virginiana (W).

Histopathology: Virus can be best detected in leaves, mesophyll, epidermis and vascular parenchyma particularly in adjoining xylem vessels. Virions are found in the cytoplasm (where unique spike structures are observed when stained with UA).

Cytopathology: Inclusions are present in infected cells. Inclusion bodies in the host cell are found in the cytoplasm. Cytoplasmic inclusions are viroplasma. Inclusions contain mature virions.

Geographical Distribution

The virus spreads in Africa. The virus occurs in Australia, Brazil, Canada, Chile, China, Czechoslovakia (former), Germany, Hungary, Ireland, Italy, Japan, the United States of America, and the USSR (former) (Schöniger, 1958).

List of Strains and Isolates in the Species

Possibly Erdbeer-Nekrose virus (Schöniger, 1958; Domes, 1957).
