Bacilladnaviridae

Bacilladnaviridae is a family of viruses that infect diatoms. The family name is derived from the words Bacillariophyta (the scientific name for diatoms) and DNA, indicating that these viruses carry their genetic material in the form of DNA.

Taxonomy

The family Bacilladnaviridae consists of a single genus, Bacilladnavirus. This genus includes two species: Chaetoceros salsugineum DNA virus and Chaetoceros tenuissimus DNA virus.

Structure

Viruses in Bacilladnaviridae are non-enveloped, with icosahedral geometries, and T=189 symmetry. The diameter is around 34 nm. Genomes are circular, around 34.5kb in length.

Life Cycle

Viral replication is nuclear. DNA-templated transcription is the method of transcription. The virus exits the host cell by nuclear envelope breakdown. Diatoms serve as the natural host.

Clinical Significance

While Bacilladnaviridae primarily infect diatoms, they have no known direct impact on human health. However, diatoms play a crucial role in marine ecosystems, including the global carbon cycle, and viruses that infect them can have significant indirect effects.
