Stable coexistence between an archaeal virus and the dominant methanogen of the human gut [PDF]
Nature CommunicationsThe human gut virome, which is mainly composed of bacteriophages, also includes viruses infecting archaea, yet their role remains poorly understood due to lack of isolates.

A previously undescribed archaeal virus suppresses host immunity [PDF]
EMBO ReportsExtremophilic archaea can have chronic viral infections that are well-tolerated by the hosts and may potentially protect against more lethal infections.

Structural insights into a spindle-shaped archaeal virus with a sevenfold symmetrical tail [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 2022 Archaeal viruses with a spindle-shaped virion are abundant and widespread in extremely diverse environments. However, efforts to obtain the high-resolution structure of a spindle-shaped virus have been unsuccessful. Here, we present the structure of SSV19, a spindle-shaped virus infecting the hyperthermophilic archaeon

A filamentous archaeal virus is enveloped inside the cell and released through pyramidal portals [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 2021 International audienceThe majority of viruses infecting hyperthermophilic archaea display unique virion architectures and are evolutionarily unrelated to viruses of bacteria and eukaryotes.

Characterization of an archaeal virus-host system reveals massive genomic rearrangements in a laboratory strain [PDF]
Frontiers in Microbiology, 2023 Halophilic archaea (haloarchaea) are known to exhibit multiple chromosomes, with one main chromosome and one or several smaller secondary chromosomes or megaplasmids.

Discovery and Characterization of Thermoproteus Spherical Piliferous Virus 1: a Spherical Archaeal Virus Decorated with Unusual Filaments. [PDF]
Journal of Virology, 2020 High-temperature environments have proven to be an important source for the discovery of new archaeal viruses with unusual particle morphologies and gene content. Our isolation of Thermoproteus spherical piliferous virus 1 (TSPV1), with numerous filaments extending from the virion surface, expands our understanding of viral diversity and provides new ...

The halophilic archaeon Halogranum roseipondis sp. nov. is susceptible to a virus carrying an exceptionally high number of viral tRNA genes [PDF]
Microbiology SpectrumArchaea constitute a diverse group of organisms, many of which inhabit extreme environments, such as haloarchaea that dominate hypersaline ecosystems, like solar salterns.

S-layer architecture and glycosylation and their role in shaping virus–host specificity in prokaryotes [PDF]
Frontiers in MicrobiologyThe crystalline surface layer (S-layer) of prokaryotes constitutes a critical macromolecular interface governing virus–host interactions. In this review, we synthesize recent findings regarding the role of S-layer glycoproteins as viral receptors ...

A Survey of Protein Structures from Archaeal Viruses
Life, 2013 Viruses that infect the third domain of life, Archaea, are a newly emerging field of interest. To date, all characterized archaeal viruses infect archaea that thrive in extreme conditions, such as halophilic, hyperthermophilic, and methanogenic ...

Two coinfecting archaeal viruses provide insights into virus-virus interactions [PDF]
Communications BiologyVirus–virus interactions can profoundly shape viral ecology and evolution, yet they remain poorly understood, particularly in haloarchaea. Upon characterization of a spindle-shaped virus, Tebenquiche spindle-shaped virus 1 (Tebi-SV1), isolated from ...
