Table of Contents

Classification

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

ICTVdB Virus Code: 00.051.0.05. Virus accession number: 051005GE.
NCBI Taxon Identifier NCBI Taxonomy ID: 10501.

Name, Synonyms and Lineage

Virus is of the family 00.051. Phycodnaviridae.

Virion Properties

Morphology

Virions consist of a capsid. Virus capsid is not enveloped, round with polyhedral symmetry. The isometric capsid has a diameter of 150-190 nm. The capsid shells of virions are composed of multiple layers. Capsids appear hexagonal in outline.

Physicochemical and Physical Properties

Virions have a buoyant density in CsCl of 1.25-1.3 g cm-3.

Nucleic Acid

The Mr of the genome constitutes 21-25% of the virion by weight. The genome is not segmented and contains a single molecule of linear double-stranded DNA. The complete genome is 300000-350000 nucleotides long. The genome has a guanine + cytosine content of 40-52 %. The genome contains unusual bases, they are 5-methyl deoxy-cytosine residues and N6-methyl deoxy-adenosine residues. Double stranded DNA is non-permuted; the genome sequence has termini with cross-linked hairpin ends. The genome has terminally redundant sequences. The terminally redundant sequences have inverted terminal repetitions (ITR).

GenBank records for nucleotide sequences; complete genome sequences.

Proteins

Proteins constitute about 64% of the particle weight.

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

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.
