Name
The name Dinodnavirus reflects its host and genome, derived from "Dino" (dinoflagellate) and "dna" (double-stranded DNA genome). The genus is part of the order Dinodnavirales.
Virology
- Capsid Structure: The virus has an icosahedral capsid with a diameter of approximately 200 nanometers.
- Genome: The viral genome consists of a single molecule of double-stranded DNA about 356 kilobases in length.
- Host: It specifically infects the dinoflagellate Heterocapsa circularisquama.
- Replication: During the replication cycle, new virions are formed within a specialized cytoplasmic compartment called the viroplasm, which is created by the virus in the host cell.
Taxonomy
Originally classified in the family Phycodnaviridae, later DNA studies have shown that the genus belongs to the family Asfarviridae, revealing a closer relationship to members of this family.
