Table of Contents

Classification

This is a description of a fungal or protozoan virus at the family level.

ICTVdB Virus Code: 00.075. Virus accession number: 00075FAM. Obsolete virus code: 75.; superceded accession number: 75000000.
NCBI Taxon Identifier NCBI Taxonomy ID: 11006.

Name, Synonyms and Lineage

Synonym(s): Monopartitie dsRNA mycovirus.

Virion Properties

Morphology

Virions consist of a capsid. Virus capsid is not enveloped, round with icosahedral symmetry. The isometric capsid has a diameter of 30-40 nm.

Physicochemical and Physical Properties

Virions have a buoyant density in CsCl of 1.3-1.42 g cm-3.

Nucleic Acid

The genome is monopartite, only one particle size is recovered of linear, double-stranded RNA. The complete genome is 4700-6700 nucleotides long. The 5'-end of the genome does not have cap. Each virion contains a single copy of the genome plus a subgenomic RNA (of 1100 nucleotides packed in low frequency).

GenBank records for nucleotide sequences; complete genome sequences.

Proteins

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

Lipids

Lipids are not reported.

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.
