Heterogeneity of small plasmids from halophilic archaea [PDF]
Journal of Bacteriology, 1993 Small multicopy plasmids in three strains of halophilic archaea, SB3, GRB, and GN101, were found to be present in a cell as a population of related but not identical sequences. Two types of heterogeneity were observed: macroheterogeneity, represented by two major plasmid sequence versions homologous to each other by 80%, and microheterogeneity, in ...

Bipyrimidine Signatures as a Photoprotective Genome Strategy in G + C-rich Halophilic Archaea
Life, 2016 Halophilic archaea experience high levels of ultraviolet (UV) light in their environments and demonstrate resistance to UV irradiation. DNA repair systems and carotenoids provide UV protection but do not account for the high resistance observed.

Nitrogen regulation of protein–protein interactions and transcript levels of GlnK PII regulator and AmtB ammonium transporter homologs in Archaea [PDF]
, 2013 Gene homologs of GlnK PII regulators and AmtB-type ammonium transporters are often paired on prokaryotic genomes, suggesting these proteins share an ancient functional relationship.

Halophilic Archaea: Life with Desiccation, Radiation and Oligotrophy over Geological Times [PDF]
Life, 2015 Halophilic archaebacteria (Haloarchaea) can survive extreme desiccation, starvation and radiation, sometimes apparently for millions of years. Several of the strategies that are involved appear specific for Haloarchaea (for example, the formation of halomucin, survival in fluid inclusions of halite), and some are known from other prokaryotes (dwarfing ...

Regulation of osmoadaptation in the moderate halophile Halobacillus halophilus : chloride, glutamate and switching osmolyte strategies [PDF]
, 2008 The moderate halophile Halobacillus halophilus is the paradigm for chloride dependent growth in prokaryotes. Recent experiments shed light on the molecular basis of the chloride dependence that is reviewed here.

Proteomic properties reveal phyloecological clusters of Archaea.
PLoS ONE, 2012 In this study, we propose a novel way to describe the variety of environmental adaptations of Archaea. We have clustered 57 Archaea by using a non-redundant set of proteomic features, and verified that the clusters correspond to environmental adaptations

GenomeFingerprinter and universal genome fingerprint analysis for systematic comparative genomics [PDF]
, 2013 How to compare whole genome sequences at large scale has not been achieved via conventional methods based on pair-wisely base-to-base comparison; nevertheless, no attention was paid to handle in-one-sitting a number of genomes crossing genetic category ...

HaloDom: a new database of halophiles across all life domains
Journal of Biological Research - Thessaloniki, 2018 Background Halophilic organisms may thrive in or tolerate high salt concentrations. They have been studied for decades and a considerable number of papers reporting new halophilic species are being published every year.
