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.

Viral Hijack of Filamentous Surface Structures in Archaea and Bacteria
Viruses, 2021 The bacterial and archaeal cell surface is decorated with filamentous surface structures that are used for different functions, such as motility, DNA exchange and biofilm formation. Viruses hijack these structures and use them to ride to the cell surface

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

Structural insights into the mechanism of archaellar rotational switching
Nature Communications, 2022 Signal transduction via phosphorylated CheY is conserved in bacteria and archaea. In this study, the authors employ structural biochemistry combined with cell biology to delineate the mechanism of CheY recognition by the adaptor protein CheF.

Insights into the spool-like architecture and infection strategy of an enveloped archaeal virus. [PDF]
Sci AdvArchaeal viruses are well known for their diverse morphologies and extreme stability. Here, we used cryo–electron tomography to analyze the structure of Sulfolobus ellipsoid virus 1 (SEV1), an archaeal virus with an ellipsoidal shape and a lipid envelope, and its infection strategy.

Metagenomic analysis reveals unexplored diversity of archaeal virome in the human gut
Nature Communications, 2022 The human gut microbiome has been extensively explored, while the archaeal viruses remain largely unknown. Here, we present a comprehensive analysis of the archaeal viruses from the human gut metagenomes and the existing virus collections using the ...

Influence of N-Glycosylation on Virus–Host Interactions in Halorubrum lacusprofundi
Viruses, 2023 N-glycosylation is a post-translational modification of proteins that occurs across all three domains of life. In Archaea, N-glycosylation is crucial for cell stability and motility, but importantly also has significant implications for virus–host ...
