Morphotypes of virus-like particles in two hydrothermal vent fields on the East Scotia Ridge, Antarctica [PDF]
, 2014 Viruses from extreme environments are still largely unexplored and may harbor unseen genetic potential. Here, we present a first glance at the morphological diversity of virus like particles (VLPs) from an environment that is extreme in more than one ...

Influence of soil properties on archaeal diversity and distribution in the McMurdo Dry Valleys, Antarctica [PDF]
, 2014 Archaea are the least understood members of the microbial community in Antarctic mineral soils. Although their occurrence in Antarctic coastal soils has been previously documented, little is known about their distribution in soils across the McMurdo Dry ...

Biochemical and Phylogenetic Characterization of the dUTPase from the Archaeal Virus SIRV [PDF]
Journal of Biological Chemistry, 1998 The derived amino acid sequence from a 474-base pair open reading frame in the genome of the Sulfolobus islandicus rod-shaped virus SIRV shows striking similarity to bacterial dCTP deaminases and to dUTPases from eukaryotes, bacteria, Poxviridae, and Retroviridae.

Structure and assembly of archaeal viruses
, 2020 International audienceViruses of archaea represent one of the most enigmatic parts of the virosphere. Most of the characterized archaeal viruses infect extremophilic hosts and display remarkable diversity of virion morphotypes, many of which have never ...

His1, an Archaeal Virus of theFuselloviridae Family That Infects Haloarcula hispanica [PDF]
Journal of Virology, 1998 ABSTRACT A novel archaeal virus, His1, was isolated from hypersaline waters in southeastern Australia. It was lytic, grew only on Haloarcula hispanica (titers of up to 1011 PFU/ml), and displayed a lemon-shaped morphology (74 by 44 nm) previously reported only for a virus of the extreme thermophiles (SSV1).

Bacterial and Archaeal Viruses of Himalayan Hot Springs at Manikaran Modulate Host Genomes
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 ...

The Molecular Mechanism of Cellular Attachment for an Archaeal Virus
The FASEB Journal, 2020 Sulfolobus turreted icosahedral virus (STIV) is a model archaeal virus with a pseudo‐T=31 icosahedral virion with a mass of ~64 mega‐Daltons. Although STIV employs pyramidal lysis structures to exit the host, knowledge of the viral entry process is lacking.
