Taxonomy

Virus Code. 51.0.1.1. Virus Accession number 51011000.

Virus infects algae.

Description is on taxonomic level of serogroup. Virus belongs to the genus Phycodnavirus (VC 51.0.1. ); family Phycodnaviridae (VC 51. ).

Properties of Virion

Morphology

Virions not enveloped. Virion attaches to host cell surface and releases DNA into the host cell in a similar fashion as tectiviridae. Nucleocapsids isometric. Capsid shell of virion composed of multiple layers (multilaminated capsid). Nucleocapsids 150-190 nm in diameter. Symmetry polyhedral. Nucleocapsids appear to be angular.

Nucleic Acid

Virions contain 21-25 % nucleic acid. Virions contain one molecule of linear double stranded DNA.

Total genome length is 300000-350000 nt. Double stranded DNA non-permuted. Termini have sequences with cross-linked hairpin ends. Genome sequence minus the hairpin has terminal repeated sequences; inverted terminal repetitions (ITR) (for at least 2000 bases). Guanine + cytosine ratio 40-52 %. Unusual bases are found (varying from 0.1-47 %). Special nucleotides found in genome, are 5-methyl deoxy-cytosine residues and N6-methyl deoxy-adenosine residues (in some DNAs).

Proteins

Virions contain 64 % protein.

Lipids

Virions contain 5-10 % lipid (beneath the outer glycoprotein shell).

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