Rauchvirus
Virus classification
(unranked): Virus
Realm: Duplodnaviria
Kingdom: Heunggongvirae
Phylum: Uroviricota
Class: Caudoviricetes
Order: Caudovirales
Family: Podoviridae
Genus: Rauchvirus
Synonyms
  • BPP-1-like viruses

Rauchvirus is a genus of viruses in the order Caudovirales, in the family Podoviridae. Bacteria serve as natural hosts. The genus contains only one species: Bordetella virus BPP1.[1][2]

Structure

Viruses in Rauchvirus are non-enveloped, with icosahedral and head-tail geometries, and T=7 symmetry. The diameter is around 67 nm. Genomes are linear, around 42kb in length, and usually encodes about 50 proteins. The Bordetella phages of this genus contains an RNA-directed DNA polymerase which plays a role in tropism.[1][3] [4]

Life cycle

Viral replication is cytoplasmic. Entry into the host cell is achieved by adsorption into the host cell. DNA-templated transcription is the method of transcription. Bacteria serve as the natural host. Transmission routes are passive diffusion.[1]
