Dinodnavirus is a genus of viruses that infect dinoflagellates.[1] This genus belongs to the clade of nucleocytoplasmic large DNA viruses. The only species in the genus is Heterocapsa circularisquama DNA virus 01.[2]
Name
[edit]The order name, Dinodnavirales, is a combination of Dino, from host dinoflagellate and dna, from its DNA genome. [3]
Virology
[edit]The virus has an icosahedral capsid ~200 nanometers in diameter.[citation needed]
The genome is a single molecule of double stranded DNA of a ~356-kilobases.[citation needed]
It infects the dinoflagellate Heterocapsa circularisquama.
During replication virions emerge from a specific cytoplasm compartment – the 'viroplasm' – which is created by the virus.[4]
Taxonomy
[edit]The sole species was originally thought to belong to the family Phycodnaviridae.
DNA studies have shown that the genus belongs in the family Asfarviridae.[5][6]
