Salactin, a dynamically unstable actin homolog in Haloarchaea
mBio, 2023 ABSTRACT Across the domains of life, actin homologs are integral components of many essential processes, such as DNA segregation, cell division, and cell shape determination. Archaeal genomes, like those of bacteria and eukaryotes, also encode actin homologs, but much less is known about these proteins’

Microorganisms, 2023 Ultraviolet (UV) radiation responses of extremophilic and archaeal microorganisms are of interest from evolutionary, physiological, and astrobiological perspectives. Previous studies determined that the halophilic archaeon, Halobacterium sp. NRC-1, which

Polyploidy in haloarchaea: advantages for growth and survival [PDF]
Frontiers in Microbiology, 2014 The investigated haloarchaeal species, Halobacterium salinarum, Haloferax mediterranei, and H. volcanii, have all been shown to be polyploid. They contain several replicons that have independent copy number regulation, and most have a higher copy number during exponential growth phase than in stationary phase.

Haloarchaeal Carotenoids: Healthy Novel Compounds from Extreme Environments
Marine Drugs, 2019 Haloarchaea are halophilic microorganisms belonging to the archaea domain that inhabit salty environments (mainly soils and water) all over the world. Most of the genera included in this group can produce carotenoids at significant concentrations (even ...

Amino acid substitutions in cold-adapted proteins from Halorubrum lacusprofundi, an extremely halophilic microbe from antarctica. [PDF]
PLoS ONE, 2013 The halophilic Archaeon Halorubrum lacusprofundi, isolated from the perennially cold and hypersaline Deep Lake in Antarctica, was recently sequenced and compared to 12 Haloarchaea from temperate climates by comparative genomics.

Biogeography at the limits of life: Do extremophilic microbial communities show biogeographical regionalization? [PDF]
, 2017 Aim Biogeographical regions are the fundamental geographical units for grouping Earth's biodiversity. Biogeographical regionalization has been demonstrated for many higher taxa, such as terrestrial plants and vertebrates, but not in microbial communities.

Halovirus HF2 Intergenic Repeat Sequences Carry Promoters
Viruses, 2021 Halovirus HF2 was the first member of the Haloferacalesvirus genus to have its genome fully sequenced, which revealed two classes of intergenic repeat (IR) sequences: class I repeats of 58 bp in length, and class II repeats of 29 bp in length.

Denitrifying haloarchaea: sources and sinks of nitrogenous gases [PDF]
FEMS Microbiology Letters, 2017 Haloarchaea thrive under saline and hypersaline conditions and often dominate microbial communities in saltmarshes, salted lakes/soils and some oceanic areas. Some of the predominant species show denitrifying capabilities, although it remains unclear whether they are complete or partial denitrifiers.
