Table of Contents

Classification

This is a description of an invertebrate virus at the genus level.

ICTVdB Virus Code: 00.101.0.01. Virus accession number: 101001GE. Obsolete virus code: 52.0.U.; superceded accession number: 520u0000.
NCBI Taxon Identifier NCBI Taxonomy ID: 144051.

Name, Synonyms and Lineage

The taxon has the accepted ICTV name.

Virus is of the family 00.101. Dicistroviridae.

Virion Properties

Morphology

Virions consist of a capsid. Virus capsid is not enveloped, round with icosahedral symmetry. The isometric capsid has a diameter of 27-30 nm. Capsids appear round. The capsid consists of 12 capsomers.

Physicochemical and Physical Properties

Virions have a buoyant density in CsCl of 1.35-1.37 g cm-3.

Nucleic Acid

The genome is not segmented and contains a single molecule of linear positive-sense, single-stranded RNA. The genome is infectious. The complete genome is 8500-9500 nucleotides long. The 5'-end of the genome has a genome-linked protein (VPg). The 5'-terminus has a poly (C) tract. The 3'-terminus has a poly (A) tract.

GenBank records for nucleotide sequences; complete genome sequences.

Proteins

The viral genome encodes structural proteins, or non-structural proteins. Virions consist of 3 structural protein(s) located in the capsid.

Lipids

Lipids are absent.

Genome Organization and Replication

By itself, genomic nucleic acid is infectious.

Taxonomic Proposals and Changes

At the meeting in Washington, DC, April 2001, it was proposed to change the name from "Cricket paralysis-like viruses" to Cripavirus). The proposal has been approved by postal ballot following discussions at the meeting of the Executive Committee in Houston, March 2002, the taxon has been designated as Genus (in the newly created Family Dicistroviridae).
