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.

Stable coexistence between an archaeal virus and the dominant methanogen of the human gut [PDF]

Nature Communications
The 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 Reports
Extremophilic archaea can have chronic viral infections that are well-tolerated by the hosts and may potentially protect against more lethal infections.

Snapshots of Motion: A Novel Structural Intermediate Reveals Conserved Dynamics in Archaeal DNA Ligases. [PDF]

Proteins
ABSTRACT We present the first x‐ray crystallographic structural evidence of an archaeal DNA ligase showing the AMP covalent adduct together with further cofactor hydrolysis, capturing a transient intermediary in the first step of the ligation reaction, triggered by the pyrophosphate hydrolysis.

Blastocystis presence alters gut archaeal communities and metabolic functions in Tibetan antelopes (Pantholops hodgsonii) [PDF]

Frontiers in Veterinary Science
BackgroundArchaea are vital members of the gut microbiota, yet their diversity and functions in high-altitude wildlife remain poorly understood. Understanding their ecological roles can provide insights into host health and microbial community dynamics ...

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
