''Yuavirus'' 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 six species in this genus.
Taxonomy
The following species are recognized:
* ''
Alphaproteobacteria virus phiJl001
Alphaproteobacteria is a class of bacteria in the phylum Pseudomonadota (formerly Proteobacteria). The Magnetococcales and Mariprofundales are considered basal or sister to the Alphaproteobacteria. The Alphaproteobacteria are highly diverse and p ...

Pseudomonas virus Yua''
Structure
Yuaviruses 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.
Genome
All species have been fully sequenced. They range between 58-64k nucleotides, with 77-90 proteins.
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.
History
According to
ICTV'
2012 report the genus was accepted under the name ''Yualikevirus'', assigned to family ''
Siphoviridae'', order ''
Caudovirales''.
The genus was later renamed to ''Yuavirus''.
