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.

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.

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.

A Unique m6A-Dependent Restriction Endonuclease from an Archaeal Virus [PDF]
Microbiology Spectrum, 2023 Many modification-dependent restriction endonucleases (MDREs) were identified in prokaryotes and recognized modified cytosine bases, such as 5-methylcytosine (5mC), 5-hydroxymethylcytosine (5hmC), and glucosyl-5-hydroxymethylcytosine (g5hmC). The first virus-derived MDRE (HHPV4I) from the archaeal virus HHPV4 was identified in this study.

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

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 ...

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 ...
