Autographivirinae
Encyclopedia
Autographivirinae are a subfamily
of virus
es within the Podoviridae
family.
s related to coliphage T7, as members of the Podoviridae
family. Enterobacteriaceae phages SP6 and K1-5 were the first to be considered as an estranged subgroup of the "T7-like viruses".
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 Podoviridae
family. The name of this subfamily, termed Autographivirinae, refers to the “auto-graphein” or “self-transcribing” phages which encode their own (single subunit) RNA polymerase, a common characteristic among its members.
Currently, the Autographivirinae are subdivided in three genera: the "T7-like viruses", the "phiKMV-like viruses
" and the "SP6-like viruses". Unclassified members include cyanophages P60, syn5 and P-SSP7. Other bacteriophages like Bacteriophage SIO1 and VpV262 are evolutionary related to the Autographivirinae, but do not contain a phage-encoded RNA polymerase and show greater differences at the genome organization level.
Taxonomy
Taxonomy is the science of identifying and naming species, and arranging them into a classification. The field of taxonomy, sometimes referred to as "biological taxonomy", revolves around the description and use of taxonomic units, known as taxa...

History
Since the 1990s, the term "T7 supergroup" has been coined for the expanding group of bacteriophageBacteriophage
A bacteriophage is any one of a number of viruses that infect bacteria. They do this by injecting genetic material, which they carry enclosed in an outer protein capsid...

PhiKMV-like viruses
PhiKMV-like viruses are a genus of Autographivirinae viruses.Bacteriophage phiKMV and its relatives are known to be highly virulent phages, producing large clear plaques upon plating on a susceptible host. The only reported exception is phage LKA1, which yields small plaques surrounded by a halo....
