Metavirus

Metavirus is a genus of viruses in the family Metaviridae, in the realm Riboviria. There are 11 species in this genus. The viruses in this genus infect fungi.

Taxonomy

The following species are recognized:

• Metavirus australensis
• Metavirus borealis
• Metavirus brasiliensis
• Metavirus canadensis
• Metavirus chilensis
• Metavirus frigidus
• Metavirus japonicus
• Metavirus novaezelandiae
• Metavirus orientalis
• Metavirus polynesiensis
• Metavirus septentrionalis

Structure

Viruses in Metavirus are non-enveloped, with icosahedral and round geometries, and T=3 symmetry. The diameter is around 30-40 nm. Genomes are linear and non-segmented, around 4.6-4.7 kb in length.

Life Cycle

Viral replication is cytoplasmic. Entry into the host cell is achieved by penetration into the host cell. Replication follows the positive stranded RNA virus replication model. Positive stranded RNA virus transcription is the method of transcription. The virus exits the host cell by tubule-guided viral movement. Fungi serve as the natural host.

Clinical

The clinical relevance of the Metavirus is currently under investigation. As it is a virus that infects fungi, it does not directly cause disease in humans or animals. However, it may have indirect effects on human health by affecting the populations of fungi in the environment.
