¹List does not include numerous unclassified viruses.
²Addenda to classifications are supplied where present. These include (C.) order Caudovirales, (G.) subfamily Gokushovirinae, (P.) order Picornavirales, (Se.) subfamily Sedoreovirinae, (Sp.) subfamily Spinareovirinae, (T.) order Tymovirales.
³Domain Archaea, domain Bacteria, kingdom Fungi, or kingdom Protista, the latter of Whittaker’s [83] Five-Kingdom System.
⁴Contains approximately 1 kb of dsDNA region within approximately 6 kb genomes; may also be listed as Bacillariodnavirus, in either case serving as conjunctions of “Bacillariophyta”, “DNA”, and “virus”.
⁵This taxon is not ICTV listed.
⁶Bacillariornaviridae Bacillariornavirus is listed as the taxonomic description of Chaetoceros socialis f. radians RNA virus, a diatom virus, by both the RNA Virus Database (http://newbioafrica.mrc.ac.za/rnavirusdb/) and NCBI. In Tomaru et al. [84] the isolation of this virus is described and they propose there its classification also into family Bacillariornaviridae. The same virus, however, is indicated as belonging to the genus Bacillarnavirus by ICTV, with unassigned family, and so too does Tomaru et al. [85]. The type species of this group of viruses, Rhizosolenia setigera RNA virus 01 (also a diatom virus), as well as Chaetoceros tenuissimus RNA virus 01, neither of which is indexed by NCBI, appears to be associated exclusively with Bacillarnavirus both by ICTV and online sources. In any case, the terms are conjunctions of “Bacillariophyta”, “RNA”, and “virus”.
