Name, Synonyms and Lineage

Synonym(s): Carnation ringspot virus group. Virus is of the family 00.074. Tombusviridae.

Virion Properties

Morphology

Virions consist of a capsid. Virus capsid is not enveloped, round with icosahedral symmetry. The isometric capsid has a diameter of 31-33.87-35 nm. Capsids appear round, or hexagonal in outline. The capsid surface structure reveals a regular pattern with distinctive features (granular). The capsomer arrangement is clearly visible, or is not obvious.

Electron microscopic preparation and references: Virus preparation contains few virions, or many virions.

Physicochemical and Physical Properties

Virions have a buoyant density in CsCl of 1.363-1.364-1.366 g cm-3. There are 1 sedimenting component(s) found in purified preparations. The sedimentation coefficient is 126-132-135 S20w. Isoelectric point pH is 4.5. A260/A280 ratio is 1.64-1.72-1.8. The thermal inactivation point (TIP) is at 80-85.83-90°C. The longevity in vitro (LIV) is 50-60.75-70 days. Although the titer is dependent on the host, the decimal exponent (DEX) of the dilution end point is usually around 5, or 6-7. The infectivity is decreased by treatment with ether, or not changed by treatment with ether; retained when deproteinized with phenol or detergent.

Nucleic Acid

The Mr of the genome constitutes 20-22.87-28% of the virion by weight. The genome is segmented; bipartite, segements are distributed among 2 particle types of linear, positive-sense, single-stranded RNA. Minor species of non-genomic nucleic acid are also found in virions. The complete genome is 5300 nucleotides long. The RNA-1.   Is sequenced, complete sequence is about 1448-1499-1600 nucleotides long (RNA-2). The genome has a base ratio of 26 % guanine; 27 % adenine; 23 % cytosine; 24 % uracil. The 5'-end of the genome has a methylated nucleotide cap; cap sequence type is m7GpppA. The multipartite genome is divided among different particles, each segment encapsidated separately.

GenBank records for nucleotide sequences; complete genome sequences.

Proteins

Proteins constitute about 72-77.12-80% of the particle weight.

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

Non-Structural Proteins: Virus-coded non-structural proteins have been identified by sequence analysis and 3 non-structural protein(s) are found.

Lipids

Lipids are not reported.

Genome Organization and Replication

By itself, genomic nucleic acid is infectious.

Transcription: Sub-genomic RNA is present in infected cells.
