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

Haloquadratum walsbyi : Limited Diversity in a Global Pond
PLoS ONE, 2011 BackgroundHaloquadratum walsbyi commonly dominates the microbial flora of hypersaline waters. Its cells are extremely fragile squares requiring >14%(w/v) salt for growth, properties that should limit its dispersal and promote geographical isolation and ...

Ser262 determines the chloride-dependent colour tuning of a new halorhodopsin from Haloquadratum walsbyi [PDF]
Bioscience Reports, 2012 Light is an important environmental signal for all organisms on earth because it is essential for physiological signalling and the regulation of most biological systems.

Novel viruses of Haloquadratum walsbyi expand the known archaeal virosphere of hypersaline environments [PDF]
ISME JournalAbstract Solar salterns represent unique systems with low diversity microbial communities that serve as an excellent model for studying the evolution and ecology of archaeal viruses and the interactions with their hosts. This is particularly relevant for the extremely abundant “square” archaeon Haloquadratum walsbyi, for which isolated ...

Global dominance of Haloquadratum walsbyi by a single genomovar with distinct gene content and viral cohorts from close relatives [PDF]
ISME JournalAbstract Haloquadratum walsbyi is generally the dominant species in hypersaline ecosystems at salt saturation conditions. Here, we followed the dynamics of its genomovars and associated viruses during recurrent evaporation-dilution disturbances of varying intensities at the mesocosm scale over 813 days.

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.
