New virus isolates from Italian hydrothermal environments underscore the biogeographic pattern in archaeal virus communities. [PDF]

ISME J, 2020
International audienceViruses of hyperthermophilic archaea represent one of the least understood parts of the virosphere, showing little genomic and morphological similarity to viruses of bacteria or eukaryotes.

Structure of a filamentous virus uncovers familial ties within the archaeal virosphere [PDF]

Virus Evolution, 2020
International audienceViruses infecting hyperthermophilic archaea represent one of the most enigmatic parts of the global virome, with viruses from different families showing no genomic relatedness to each other or to viruses of bacteria and eukaryotes ...

Unique architecture of thermophilic archaeal virus APBV1 and its genome packaging. [PDF]

Nat Commun, 2017
Archaeal viruses have evolved to infect hosts often thriving in extreme conditions such as high temperatures. However, there is a paucity of information on archaeal virion structures, genome packaging, and determinants of temperature resistance.

Virus-borne mini-CRISPR arrays are involved in interviral conflicts

Nature Communications, 2019
Here, the authors investigate the diversity and dynamics of the CRISPRome in the hyperthermophilic archaea of the order Sulfolobales, and find the most abundant spacers to come from mini-CRISPR arrays of archaeal viruses, which might represent a strategy

The Molecular Mechanism of Cellular Attachment for an Archaeal Virus [PDF]

SSRN Electronic Journal, 2019
Sulfolobus turreted icosahedral virus (STIV) is a model archaeal virus and member of the PRD1-adenovirus lineage. Although STIV employs pyramidal lysis structures to exit the host, knowledge of the viral entry process is lacking.

Putative archaeal viruses from the mesopelagic ocean [PDF]

PeerJ, 2017
Oceanic viruses that infect bacteria, or phages, are known to modulate host diversity, metabolisms, and biogeochemical cycling, while the viruses that infect marine Archaea remain understudied despite the critical ecosystem roles played by their hosts ...

Characterization of the lytic archaeal virus Drs3 infecting Methanobacterium formicicum

Archives of Virology, 2019
Viruses are ubiquitous in the biosphere and greatly affect the hosts they infect. It is generally accepted that members of every microbial taxon are susceptible to at least one virus, and a plethora of bacterial viruses are known.

ORF4 of the Temperate Archaeal Virus SNJ1 Governs the Lysis-Lysogeny Switch and Superinfection Immunity. [PDF]

J Virol, 2020
International audienceRecent environmental and metagenomic studies have considerably increased the repertoire of archaeal viruses and suggested that they play important roles in nutrient cycling in the biosphere.
