Archaeal virus entry and egress. [PDF]

MicroLife
Archaeal viruses display a high degree of structural and genomic diversity. Few details are known about the mechanisms by which these viruses enter and exit their host cells.

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.

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 ...

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.

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 ...

Bacterial and Archaeal Viruses of Himalayan Hot Springs at Manikaran Modulate Host Genomes [PDF]

Frontiers in Microbiology, 2018
Hot spring-associated viruses, particularly the archaeal viruses, remain under-examined compared to bacteriophages. Previous metagenomic studies of the Manikaran hot springs in India suggested an abundance of viral DNA, which prompted us to examine the ...
