Characteristics [ edit ]

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]
