Autographiviridae is a family of
viruses in the order Caudovirales. Bacteria serve as natural hosts. There are 373 species in this family, assigned to 9 subfamilies and 133 genera.[1][2]
History
Since the 1990s, the term "T7 supergroup" has been coined for the expanding group of
coliphage T7, as members of the family Podoviridae. Enterobacteriaceae phages SP6 and K1-5 were the first to be considered as an estranged subgroup of the "T7 supergroup".[3] Pseudomonas phage phiKMV also shared commonalities at the genome organizational level. As such, based on the available morphological and proteomic data, this clade of viruses was established as a subfamily of the family Podoviridae. The subfamily was later raised to the level of family in 2019.[4]
Etymology
The name of this family, termed Autographiviridae, refers to the “auto-graphein” or “self-transcribing”
RNA polymerase, a common characteristic among its members.[citation needed
]
Structure
Viruses in Autographiviridae are non-enveloped, with icosahedral and Head-tail geometries, and T=7 symmetry. The diameter is around 60 nm. Genomes are linear, around 40-42kb in length.[1]
Life cycle
Viral replication is cytoplasmic. DNA templated transcription is the method of transcription. The virus exits the host cell by lysis, and
endolysin/spanin proteins. Bacteria serve as the natural host. Transmission routes are passive diffusion.[1]
