Bacilladnaviridae is a family of single-stranded DNA viruses that primarily infect diatoms.[1][2]

Characteristics

Genome map of species Chaetoceros protobacilladnavirus 2 of family Bacilladnaviridae

Similar to other eukaryotic ssDNA viruses, bacilladnaviruses are likely to replicate their genomes by the rolling-circle mechanism, initiated by the virus-encoded endonuclease (Rep). 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.[3] [4]
