De Novo Sequences of Haloquadratum walsbyi from Lake Tyrrell, Australia, Reveal a Variable Genomic Landscape [PDF]
Archaea, Volume 2015, Issue 1, 2015., 2015 Hypersaline systems near salt saturation levels represent an extreme environment, in which organisms grow and survive near the limits of life. One of the abundant members of the microbial communities in hypersaline systems is the square archaeon, Haloquadratum walsbyi.

The PL6-Family Plasmids of Haloquadratum Are Virus-Related [PDF]
Frontiers in Microbiology, 2018 Plasmids PL6A and PL6B are both carried by the C23T strain of the square archaeon Haloquadratum walsbyi, and are closely related (76% nucleotide identity), circular, about 6 kb in size, and display the same gene synteny. They are unrelated to other known

The genome of the square archaeon
BMC Genomics, 2006 Background The square halophilic archaeon Haloquadratum walsbyi dominates NaCl-saturated and MgCl2 enriched aquatic ecosystems, which imposes a serious desiccation stress, caused by the extremely low water activity.

Novel insights into the diversity of halophilic microorganisms and their functioning in hypersaline ecosystems [PDF]
npj BiodiversityOur understanding of the microbial diversity inhabiting hypersaline environments, here defined as containing >100–150 g/L salts, has greatly increased in the past five years. Halophiles are found in each of the three domains of life.

Phylogenomic analysis of proteins that are distinctive of
BMC Genomics, 2007 Background The Archaea are highly diverse in terms of their physiology, metabolism and ecology. Presently, very few molecular characteristics are known that are uniquely shared by either all archaea or the different main groups within archaea.

Succession and assembly mechanisms of seawater prokaryotic communities along an extremely wide salinity gradient. [PDF]
Environ Microbiol Rep, 2023 Succession and assembly mechanisms of prokaryotic communities along an extremely wide salinity gradient. Abstract Salinity is an important environmental factor in microbial ecology for affecting the microbial communities in diverse environments. Understanding the salinity adaptation mechanisms of a microbial community is a significant issue, while most

Conditional Alternative Protein Splicing Promoted by Inteins from Haloquadratum walsbyi. [PDF]
Biochemistry, 2022 Protein splicing is a post-translational process by which an intervening protein, or an intein, catalyzes its own excision from flanking polypeptides, or exteins, coupled to extein ligation. Four inteins interrupt the MCM helicase of the halophile Haloquadratum walsbyi, two of which are mini-inteins that lack a homing endonuclease.
