Bacilladnaviridae
Bacilladnaviridae is a family of single-stranded DNA viruses that primarily infect diatoms.
Characteristics
Similar to other eukaryotic ssDNA viruses, bacilladnaviruses are likely to replicate their genomes by the rolling-circle mechanism, initiated by the virus-encoded endonuclease. However, the latter protein of bacilladnaviruses displays unique conserved motifs and in phylogenetic trees forms a monophyletic clade separated from other groups of ssDNA viruses. The capsid protein of bacilladnaviruses has the jelly-roll fold and is most closely related to the corresponding proteins from members of the family Nodaviridae, which have ssRNA genomes.Taxonomy
