Name, Synonyms and Lineage

Virus is an ICTV approved species of the genus 00.060.0.01. Orthoreovirus; family 00.060. Reoviridae.

Virion Properties

Morphology

Virions consist of a capsid, a core, and a nucleoprotein complex. Virus capsid is not enveloped. Capsid/nucleocapsid is isometric with icosahedral symmetry and has a diameter of 80-82 nm. The capsid shells of virions are composed of two layers. All shells are usually present, or the outer shell is often lost during preparation. Capsids appear round. The capsid surface structure reveals a regular pattern with distinctive features. The capsomer arrangement is clearly visible. Surface projections are not present. Inner capsids have a diameter of 60 nm. Virus preparations contain one particle component. The core is spherical.

Only one species is recovered in preparations. Incomplete particles are common. They are devoid of nucleic acid characterized by capsids with dark centers in negative stain preparations, or incompletely assembled capsids.

Nucleic Acid

The Mr of the genome constitutes 15-20% of the virion by weight. The genome is monomeric; segmented and consists of ten segments of linear double-stranded RNA. The complete genome is 23700 nucleotides long. The L1 is sequenced, but only an estimate is available, complete sequence is 3800-3900 nucleotides long. L2 is sequenced, complete sequence is about 3800-3900 nucleotides long. L3 is sequenced, but only an estimate is given, complete sequence is 3800-3900 nucleotides long. M1 has been fully sequenced, complete sequence is 2200-2300 nucleotides long. M2 has been sequenced, but only an estimate is presented, complete sequence is 2200-2300 nucleotides long. M3 has been sequenced, but only an estimate is given, complete sequence is 2200-2300 nucleotides long, has been sequenced, but only an estimate is presented; complete sequence is 1200-1400 nucleotides long. S2 has been fully sequenced, complete sequence is 1200-1400 nucleotides long. S3 has been sequenced, but only an estimate is available, complete sequence is 1200-1400 nucleotides long. S4; complete sequence is 1200-1400 nucleotides long. The 5'-end of the genome has a methylated nucleotide cap; cap sequence type is m7G5ppp5'GmpNp. The multipartite genome is found in one type of particle only. Each virion contains a single copy of the genome.

GenBank records for nucleotide sequences; complete genome sequences.

Proteins

Proteins constitute about 80-85% of the particle weight.

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

Lipids

Lipids are absent.

The description has been generated automatically from DELTA files.

ICTVdB - The Universal Virus Database, developed for the International Committee on Taxonomy of Viruses (ICTV) by Dr Cornelia Büchen-Osmond, is written in DELTA. The virus descriptions in ICTVdB are coded by ICTV members and experts, or by the ICTVdB Management using data provided by the experts, the literature or the latest ICTV Report. The character list is the underlying code. All virus descriptions are based on the character list and natural language translations from the encoded descriptions are automatically generated and formatted for display on the Web.
