Yualikevirus is a genus of viruses in the family Siphoviridae, unassigned to a sub-family. Bacteria serve as the natural host, with transmission achieved through passive diffusion. There are currently three species in this genus, including the type species Pseudomonas phage Yua.[1][2][3]
Taxonomy
Species:
- Phage phiJl001
- Pseudomonas phage M6
- Pseudomonas phage Yua (type species)
Structure
Yualikeviruses are nonenveloped, with a head and tail. The head is a prolate spheroid about 72 nm by 51 nm. The tail is about 145 nm long.[1]
| Taxonomy | Structure | Symmetry | Capsid | Genomic Arrangement | Genomic Segmentation |
|---|---|---|---|---|---|
| Group I > Caudovirales > Siphoviridae > Yualikevirus | Head-Tail | T=7 | Non-Enveloped | Linear | Monopartite |
Genome
All three species have been fully sequenced. They range between 58-64k nucleotides, with 77-90 proteins. The complete genomes are available here.[3]
Life cycle
The virus attaches to the host cell using its terminal fibers, and ejects the viral DNA into the host periplasm. The DNA genome is circularized or integrate into the host's chromosome before transcription and translation. Once the viral genes have been replicated, the new virions are assembled in the cytoplasm. Finally, the mature virions are released via lysis.[1]

History
According to ICTV's 2012 report, the genus was accepted under the name Yualikevirus, assigned to family Siphoviridae, order Caudovirales.[2]
