Name, Synonyms and Lineage

ICTV approved acronym: BBWV-1. Virus is the type of the genus 00.018.0.02. Fabavirus in the family 00.018. Comoviridae.

Virion Properties

Morphology

Virions consist of a capsid. Virus capsid is not enveloped, round with icosahedral symmetry. The isometric capsid has a diameter of about 30 nm. Capsids appear hexagonal in outline. Virus preparations contain more than one particle component.

Capsids all have the same appearance.

Nucleic Acid

The genome is segmented; bipartite, segements are distributed among 2 particle types of linear, positive-sense, single-stranded RNA. The complete genome is 10900 nucleotides long. Genome is sequenced, complete sequence is about 6400 nucleotides long, is sequenced, but only an estimate is available, complete sequence is 4500 nucleotides long. The multipartite genome is divided among different particles, each segment encapsidated separately and the segments are distributed between 2 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 no nucleic acid and are found in the top (sedimenting component T) band after sedimentation.

GenBank records for nucleotide sequences; complete genome sequences.

Proteins

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

Lipids

Lipids are not reported.

Genome Organization and Replication

By itself, genomic nucleic acid is infectious (and both RNAs are required for infectivity).

Biological Properties

DELTA - DEscription Language for TAxonomy developed by Dr Mike Dallwitz, Toni Paine and Eric Zurcher, CSIRO Entomology, Canberra, Australia. 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. The description has been generated automatically from DELTA files.
