Classification

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

ICTVdB Virus Code: 00.010.0.05. Virus accession number: 010005GE. Obsolete virus code: 10.0.5.; superceded accession number: 10050000.
NCBI Taxon Identifier NCBI Taxonomy ID: 154322.

Name, Synonyms and Lineage

Virus is of the family 00.010. Bromoviridae.

Virion Properties

Morphology

Virions consist of a capsid. Virus capsid is not enveloped. Capsid is round to elongated with polyhedral symmetry. The capsid is isometric to bacilliform and has a diameter of 26 nm or a length of 37, 43, 48, and 55 nm and a width of 18 nm. Virus preparations contain more than one particle component.


































Electron micrograph of Bromoviridae.

Physicochemical and Physical Properties

Virions have a buoyant density in CsCl of 1.36 g cm-3. There are 4 sedimenting component(s) found in purified preparations.

Nucleic Acid

The genome is segmented; tripartite, segements are distribute among 3 particle types of different size; consists of four segments of linear positive-sense, single-stranded RNA. Minor species of non-genomic nucleic acid are also found in virions. The encapsidated nucleic acid is mainly of genomic origin, but virions may also contain subgenomic RNA, that is mRNA derived from genomic RNA-3. The complete genome is 8301 nucleotides long. The RNA-1 is fully sequenced, complete sequence is 3300 nucleotides long. RNA-2 is sequenced and complete sequence is about 2800 nucleotides long. RNA-3 is sequenced and complete sequence is about 2450 nucleotides long. RNA-4 is subgenomic has been sequenced, but only an estimate is provided, complete sequence is 2100 nucleotides long. Subgenomic RNA-4 is apparently not an mRNA. The genome has a guanine + cytosine content of 48.2 %. The multipartite genome segments are distributed between 3 different types of particles. The largest particles contain each one molecule of RNA-1 (sedimenting component B). The medium sized particles contain each one molecule of RNA-2 (sedimenting component M). The smallest particles contain one molecule each of RNA-3 and RNA-4 (sedimenting component T).

GenBank records for nucleotide sequences; complete genome sequences.

Proteins

The viral genome encodes structural proteins and non-structural proteins located in the capsid.

Structural Proteins: Capsid protein is involved in viral encapsidation and involved in protein movement.

Lipids

Lipids are absent.

Genome Organization and Replication

By itself, genomic nucleic acid is infectious.

Transcription: Sub-genomic RNA is present in infected cells; encoding the coat protein.

Biological Properties

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