A Unique m6A-Dependent Restriction Endonuclease from an Archaeal Virus. [PDF]
Microbiol Spectr, 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.

Diversity, taxonomy, and evolution of archaeal viruses of the class Caudoviricetes. [PDF]
PLoS Biology, 2021 The archaeal tailed viruses (arTV), evolutionarily related to tailed double-stranded DNA (dsDNA) bacteriophages of the class Caudoviricetes, represent the most common isolates infecting halophilic archaea.

Sequence analysis of an Archaeal virus isolated from a hypersaline lake in Inner Mongolia, China [PDF]
BMC Genomics, 2007 Background We are profoundly ignorant about the diversity of viruses that infect the domain Archaea. Less than 100 have been identified and described and very few of these have had their genomic sequences determined.

Characterization of Blf4, an Archaeal Lytic Virus Targeting a Member of the Methanomicrobiales [PDF]
Viruses, 2021 Today, the number of known viruses infecting methanogenic archaea is limited. Here, we report on a novel lytic virus, designated Blf4, and its host strain Methanoculleus bourgensis E02.3, a methanogenic archaeon belonging to the Methanomicrobiales, both isolated from a commercial biogas plant in Germany.

An archaeal virus capable of hydrolyzing the surface glycan of the host cell. [PDF]
mLifeImpact statementSpindle‐shaped viruses exclusively infect archaea. Fuselloviruses represent a large group of spindle‐shaped viruses and infect hyperthermophilic archaea of the order Sulfolobales. Although the first fusellovirus was identified nearly 40 years ago, the mechanism of host infection by these viruses remains poorly understood.

Archaeal Host Cell Recognition and Viral Binding of HFTV1 to Its Haloferax Host
mBio, 2023 Viruses are highly abundant and the main predator of microorganisms. Microorganisms of each domain of life are infected by dedicated viruses. Viruses infecting archaea are genomically and structurally highly diverse.

Growth Phase Dependent Cell Shape of Haloarcula
Microorganisms, 2021 Several haloarchaea are reported to be pleomorphic, while others exhibit remarkable shapes, such as squares. Recently, Haloferax volcanii was found to alter its morphology during growth.

Cellular and Genomic Properties of Haloferax gibbonsii LR2-5, the Host of Euryarchaeal Virus HFTV1
Frontiers in Microbiology, 2021 Hypersaline environments are the source of many viruses infecting different species of halophilic euryarchaea. Information on infection mechanisms of archaeal viruses is scarce, due to the lack of genetically accessible virus–host models. Recently, a new
