Susskind MM, Botstein D. Molecular genetics of bacteriophage P22. Ecogenomics and potential biogeochemical impacts of globally abundant ocean viruses. Numerous different hosts have been employed and it seems reasonable that phages exist for the vast majority of bacterial species that can be propagated in the lab. Sun, L. et al. The head genes, for example, code for proteins that interact intimately with each other in building the head structure, and these genes must co-evolve with each other to maintain those interactions. For example, mycobacteriophages Rosebush and Qyrzula are closely related and share extensive nucleotide sequence similarity. Natl Acad. & Bamford, D. H. Nucleic and amino acid sequences support structure-based viral classification. T2 phage had very high genomic sequence similarity to SV76 (99.99% identity), so we performed host range analysis of T2 with the same bacteria strains to see whether the genomic similarity translated to host range phenotypic similarity. Article Additional plausible mechanisms are by transposition, site-specific recombination, and homing endonucleases and while all these contribute they are likely also minor components. Limnol. Mol.

A shape of the phage capsid, which consists of many polygonal faces and is most commonly found as an icosahedron (polyhedron with20 faces). WebT2 phage is more properly called Enterobacteria phage T2. Their dsDNAs are linear, cyclically permuted, and terminally redundant. Microbiol. An intriguing possibility, whether they are providing a selective benefit or not, is that these genes could serve as a gene nursery, where novel genetic functions could be built by recombination and mutation among genetic sequences that have no essential role in phage survival.
