Abstract:
The family Turriviridae includes viruses with a dsDNA genome of 16-17 kbp. Virions are spherical with a diameter of approximately 75 nm and comprise a host-derived internal lipid membrane surrounded by a proteinaceous capsid shell. Members of the family Turriviridae infect extremophilic archaea of the genera Sulfolobus and Saccharolobus. Viral infection results in cell lysis for Sulfolobus turreted icosahedral virus 1 infection but other members of the family can be temperate. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the family Turriviridae, which is available at ictv.global/report/turriviridae.
Insights
The Turriviridae virus family infects extremophilic archaea. This report summarizes the International Committee on Taxonomy of Viruses findings on these dsDNA viruses, detailing their structure and host interactions.
Area of Science:
- Virology
- Archaea biology
- Molecular biology
Background:
- The Turriviridae family comprises dsDNA viruses infecting extremophilic archaea.
- Virions are spherical, approximately 75 nm in diameter, with a lipid membrane and protein capsid.
Purpose of the Study:
- To summarize the International Committee on Taxonomy of Viruses (ICTV) report on the family Turriviridae.
- To provide an overview of the taxonomy, structure, and host interactions of Turriviridae viruses.
Main Methods:
- Review and synthesis of data presented in the ICTV report.
- Analysis of viral genome, virion structure, and host-archaea interactions.
Main Results:
- Turriviridae viruses possess dsDNA genomes (16-17 kbp) and infect archaea in the genera Sulfolobus and Saccharolobus.
- Infection by Sulfolobus turreted icosahedral virus 1 leads to cell lysis, while other family members can be temperate.
Conclusions:
- The ICTV report provides a comprehensive taxonomic overview of the Turriviridae family.
- Understanding Turriviridae is crucial for archaeal virology and extremophile research.
