Biology:Dinodnavirus
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 (Dinodnavirus heterocapsae).[2][3]
Name
The order name, Dinodnavirales, is a combination of Dino, from host dinoflagellate and dna, from its DNA genome.[4]
Virology
The virus has an icosahedral capsid 180–210 nanometers in diameter.[5]
The genome is a single molecule of double stranded DNA of about 356-kilobases.[5]
It infects the dinoflagellate Heterocapsa circularisquama.[6]
During replication virions emerge from a specific cytoplasm compartment – the 'viroplasm' – which is created by the virus.[7]
Taxonomy
DNA studies have shown that the genus belongs in the family Asfarviridae.[8][9]
