Classification

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

ICTVdB Virus Code: 00.067.0.01.018. Virus accession number: 67001018. Obsolete virus code: 00.067.0.91.018.; 67.0.1.T.DE.1; superceded accession number: 67091018; 6701tde1.
NCBI Taxon Identifier NCBI Taxonomy ID: 119910.

Name, Synonyms and Lineage

The taxon is not listed in the current ICTV Report.

ICTV approved acronym: RGMoV. Virus is a tentative member. Virus is of the genus 00.067.0.01. Sobemovirus; not assigned to a family.

Virion Properties

Morphology

Virions consist of a capsid. Virus capsid is not enveloped, round with icosahedral symmetry. The isometric capsid has a diameter of 28 nm.

Physicochemical and Physical Properties

Virions have a buoyant density in CsCl of 1.366 g cm-3. There are 1 sedimenting component(s) found in purified preparations. The sedimentation coefficient is 108 S20w.

Nucleic Acid

The Mr of the genome constitutes 23% of the virion by weight. The genome is monopartite. Only one particle size of linear, positive-sense, single-stranded RNA is recovered. The complete genome is 4200 nucleotides long. Genome is sequenced, but only an estimate is available, complete sequence is 4200 nucleotides long.

GenBank records for nucleotide sequences; complete genome sequences.

Proteins

Proteins constitute about 77% of the particle weight.

The viral genome encodes structural proteins and non-structural proteins. Virions consist of 1 structural protein(s).

Lipids

Lipids are not reported.

Antigenicity

The virus does not show serological relationships to cocksfoot mild mosaic, cocksfoot mottle and cynosurus mottle viruses.

Biological Properties

Natural Host

Domain
Viral hosts belong to the Domain Eucarya.

Domain Eucarya
Kingdom Plantae.

Kingdom Plantae
Phylum Magnoliophyta (Angiosperms, Class Liliopsida (Monocotyledonae).
