Sizing chromosomes and megaplasmids in haloarchaea [PDF]
Microbiology, 1996 PFGE was used for the genomic analysis of different species and strains belonging to four out of the six recognized haloarchaeal (halobacterial) genera. All of them were found to carry one chromosome from 1.8-3 Mb, and usually several, but at least one, large plasmids of approximately 90-680 kb, which were detected in supercoiled and linear forms.

Responses of Haloarchaea to Simulated Microgravity [PDF]
Astrobiology, 2011 Various effects of microgravity on prokaryotes have been recognized in recent years, with the focus on studies of pathogenic bacteria. No archaea have been investigated yet with respect to their responses to microgravity. For exposure experiments on spacecrafts or on the International Space Station, halophilic archaea (haloarchaea)

The core and unique proteins of haloarchaea [PDF]
BMC Genomics, 2012 Abstract Background Since the first genome of a halophilic archaeon was sequenced in 2000, biologists have been advancing the understanding of genomic characteristics that allow for survival in the harsh natural environments of these organisms.

Mechanisms of Metal Resistance and Homeostasis in Haloarchaea [PDF]
Archaea, 2013 Haloarchaea are the predominant microflora of hypersaline econiches such as solar salterns, soda lakes, and estuaries where the salinity ranges from 35 to 400 ppt. Econiches like estuaries and solar crystallizer ponds may contain high concentrations of metals since they serve as ecological sinks for metal pollution and also as effective traps for river

F1000Research, 2014 The halophilic archaea (haloarchaea) live in saline environments, which are found across the globe. In addition to salinity, these niches can be quite dynamic and experience extreme conditions such as low oxygen content, radiation (gamma and UV), pH and

Ancient origin of the divergent forms of leucyl-tRNA synthetases in the Halobacteriales
BMC Evolutionary Biology, 2012 Background Horizontal gene transfer (HGT) has greatly impacted the genealogical history of many lineages, particularly for prokaryotes, with genes frequently moving in and out of a line of descent.
