Picovirinae is a subfamily of viruses in the order Caudovirales, in the family Salasmaviridae. Bacteria serve as natural hosts. There are two genera and seven species in this subfamily.^[2]^[3]

Taxonomy

The following genera and species are recognized:^[3]

Beecentumtrevirus
- Bacillus phage Nf
- Bacillus virus B103
- Bacillus virus Goe1
Salasvirus
- Bacillus virus Goe6
- Bacillus virus Gxv1
- Bacillus virus phi29
- Bacillus virus PZA

Structure

Viruses in Picovirinae are non-enveloped, with icosahedral or prolate heads of about 50–55 nm in diameter, and short tails. Genomes are linear, double stranded DNA, and are relatively small (between 16–20 kbp)-hence the term pico-virinae. Picoviruses package linear, monomeric genomes with a terminal protein covalently attached to each end.^[2]

Life cycle

Viral replication is cytoplasmic. Entry into the host cell is achieved by adsorption into the host cell. Replication follows the DNA strand displacement model. DNA-templated transcription is the method of transcription. Bacteria serve as the natural host. Transmission routes are passive diffusion.^[2]
