⚫ | 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.<ref name=Bacilladna >{{cite journal|last1=Kazlauskas|first1=D|last2=Dayaram|first2=A|last3=Kraberger|first3=S|last4=Goldstein|first4=S|last5=Varsani|first5=A|last6=Krupovic|first6=M|title=Evolutionary history of ssDNA bacilladnaviruses features horizontal acquisition of the capsid gene from ssRNA nodaviruses.|journal=Virology|date=2017|volume=504|pages=114–121|doi=10.1016/j.virol.2017.02.001|pmid=28189969|doi-access=}}</ref> <ref>{{cite journal |last1=Munke |first1=A |last2=Kimura |first2=K |last3=Tomaru |first3=Y |last4=Wang |first4=H |last5=Yoshida |first5=K |last6=Mito |first6=S |last7=Hongo |first7=Y |last8=Okamoto |first8=K |title=Primordial Capsid and Spooled ssDNA Genome Structures Unravel Ancestral Events of Eukaryotic Viruses. |journal=mBio |date=20 July 2022 |volume=13 |issue=4 |pages=e0015622 |doi=10.1128/mbio.00156-22 |pmid=35856561|pmc=9426455 }}</ref> |

The genome of these viruses appears to be unique. It consists of a single molecule of covalently closed circular single stranded DNA of 4.5-6 kilobases as well as a segment of linear ssDNA of ~1 kilobase. The linear segment is complementary to a portion of the closed circle creating a partially double stranded region. There are at least three major open reading frames in the genome. |

The virions are about 34 nanometers (nm) in diameter and accumulate in the nucleus. Mature virions are released by lysis of the host cell. |

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