Classification

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

ICTVdB Virus Code: 00.015.0.05.010. Virus accession number: 15005010. Obsolete virus code: 15.0.5.0.010; 07.0.1.0.010; superceded accession number: 15050010; 07010010.

Name, Synonyms and Lineage

ICTV approved acronym: SRV. Virus is an ICTV approved species of the genus 00.015.0.05. Badnavirus in the family 00.015. Caulimoviridae.

Virion Properties

Morphology

Virions consist of a capsid. Virus capsid is not enveloped. Capsid is elongated and exhibits icosahedral symmetry. The capsid is bacilliform. The capsid shells of virions are composed of multiple layers. With a length of 120-150 nm and a width of 25-30 nm.

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 genome has terminally redundant sequences. The terminally redundant sequences have direct terminal repeats; are reiterated internally in inverted form.

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 3 ORF(s).

Translation: Replication involves a reverse transcription step.

Biological Properties

Natural Host

Domain

Taxonomic Proposals and Changes

A taxonomic proposal has been submitted to the ICTV by the Plant Virus Subcommittee, Study Group for Caulimoviridae at the meeting in Strasburg, April 1997, to move the taxon from tentative species to species level. The proposal has been approved at the meeting of the Executive Committee in Strasburg, 1997, the taxon has been moved as an approved species to the Genus Badnavirus.
