''Bacillarnavirus'' is a genus of
virus
A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. Viruses infect all life forms, from animals and plants to microorganisms, including bacteria and archaea.

Picornavirales
''Picornavirales'' is an order of viruses with vertebrate, invertebrate, protist and plant hosts. The name has a dual etymology. First, ''picorna-'' is an acronym for poliovirus, insensitivity to ether, coxsackievirus, orphan virus, rhinovirus, ...
. Marine diatoms serve as natural hosts. There are three species in this genus.
Taxonomy
The genus contains the following three species:
*''
Chaetoceros socialis forma radians RNA virus 1''
*''
Chaetoceros tenuissimus RNA virus 01
''Chaetoceros'' is probably the largest genus of marine planktonic diatoms with approximately 400 species described, although many of these descriptions are no longer valid. It is often very difficult to distinguish between different ''Chaeto ...

Structure
Viruses in ''Bacillarnavirus'' are non-enveloped, with icosahedral, spherical, and round geometries, and T=pseudo3 symmetry. The diameter is around 30-32 nm. Genomes are linear and non-segmented, around 8.8-9.5kb in length. The genome has 2 open reading frames.

Life cycle
Viral replication is cytoplasmic. Entry into the host cell is achieved by attachment of the virus to host receptors, which mediates endocytosis. Replication follows the positive stranded RNA virus replication model. Positive stranded RNA virus transcription is the method of transcription. Marine diatoms serve as the natural host.[
