''Dinodnavirus'' is a genus of viruses that infect dinoflagellates.Tarutani K, Nagasaki K, Itakura S, Yamaguchi M (2001) Isolation of a virus infecting the novel shellfish-killing dinoflagellate ''Heterocapsa circularisquama''. Aquat Microb Ecol 23:103–111 This genus belongs to the clade of nucleocytoplasmic large DNA viruses. The only species in the genus is ''Heterocapsa circularisquama DNA virus 01''.

Name

The order name, ''Dinodnavirales,'' is a combination of ''Dino'', from host ''dinoflagellate'' and ''dna'', from its DNA genome.

Virology

The virus has an icosahedral capsid 180–210 nanometers in diameter. The genome is a single molecule of double stranded DNA of about 356-kilobases. It infects the dinoflagellate '' Heterocapsa circularisquama''. During replication virions emerge from a specific cytoplasm compartment – the 'viroplasm' – which is created by the virus.Nagasaki K, Tomaru Y, Tarutani K, Katanozaka N, Yamanaka S, Tanabe H, Yamaguchi M (2003) Growth characteristics and intraspecies host specificity of a large virus infecting the dinoflagellate ''Heterocapsa circularisquama''. Appl Environ Microbiol 69:2580–2586

Taxonomy

DNA studies have shown that the genus belongs in the family '' Asfarviridae''.Ogata H, Toyoda K, Tomaru Y, Nakayama N, Shirai Y, Claverie JM, Nagasaki K (2009) Remarkable sequence similarity between the dinoflagellate-infecting marine girus and the terrestrial pathogen African swine fever virus.
