Dinodnavirus is a genus of viruses whose membersinfect dinoflagellates . The genus is not classified as of April 2019. It is possibly a representative of the phylum Nucleocytoviricota (outdated Nucleocytoplasmic large DNA viruses , NCLDV) with giant and smallpox viruses . The name is derived from dino for dinoflagellate and DNA . The type species is the Heterocapsa circularisquama DNA virus 01 (HcDNAV, formerly HcV).
virology
The virus has an icosahedral capsid with a diameter of about 200 nm. Its genome consists of a ds-DNA with a size of approx. 356 kb . The virus infects the dinoflagellatum Heterocapsa circularisquama ( dinoflagellates: Peridiniales ). During replication , virions arise from a part of the cytoplasm called the viroplasm, which is produced by the virus.
