Basic phylogeny, gene organization, and methods of DNA replication and transcription.
ARCHAIC (ARCHAebacterial Information Collection)
Genome sequences of three Euryarchaeota species, Pyrococcus sp. OT3, Thermoplasma volcanium GSS1, and Archaeoglobus fulgidus, and related papers by the research group.
ArchaeaWeb
Links to popular press and journal articles, research news, and other sources of information about Archaea and extremophiles. Includes user comments.
Archaea
Microbiological journal devoted to original research on the Archaea. Author guide, publication schedule, and text of older articles.
Life in Extreme Environments
Links to information about thermophiles, halophiles, and other extremophiles both inside and outside of the domain Archaea.
The Archaea
General introduction, mentioning most known genera and species of Euryarchaeota and Crenarchaeota. Includes some technical details such as toxin sensitivities.
Thermophiles 2003
Programme of a conference held at the University of Exeter in September of 2003.
Journal of Biological Chemistry: Extreme Halophiles Synthesize Betaine from Glycine by Methylation
Research on the methyltransferase enzymes involved in synthesis of glycine betaine in Actinopolyspora halophila and Ectothiorhodospira halochloris. Transfer of the relevant genes increased salt tolerance in E. coli.
Joint Genome Institute: Why Sequence Crenarchaeota?
Brief discussion of the importance of these deep-sea plankton, and of the benefits to be gained by understanding their genome.
Horikoshi Superbugs
Summary of interesting organisms discovered during a search for extremophiles, including a picture of the triangular halophile Haloarcula japonicus.
Microbe from Depths Takes Life to Hottest Known Limit
A newly discovered organism thrives near deep-sea ocean vents at temperatures up to 121C, living off dissolved iron. Images, video, and links to related research. Press release from the National Science Foundation.
Open Questions: Archaea and Extremophiles
Annotated list of recommended sources.
The Limits to Life Under Dual Extremes of Temperature and Salinity
Abstract of conference speech on Halothermothrix orenii by Dr. Bharat Patel.
Halobacteria
Detailed discussion of the molecules involved in their cytoplasmic and photosynthetic membrane lipids, structural glycoproteins, ionic relationships, and photosynthetic cycle.
Domain Archaea
Minimalist introduction to the three main groups: extreme halophiles, methanogens, and hyperthermophiles.
The Scientist: Hot-Vent Microbes: Looking Backward In Evolution For Future Uses
Summary of research into the scientific uses of thermophiles and their heat-tolerant enzymes, such as PCR (polymerase chain reactions), toxic waste cleanup, and biomedical processes. [Free registration required]
Microbial Wonders Of The Deep - Halophiles
Discusses the unique lipid composition of their cell walls, bacteriorhodopsin photosynthesis, and the use of high concentrations of potassium to combat sodium osmosis.
Introduction to the Archaea
Covers their main groupings, chemical differences from other life forms, fossil record, and the structure of their cell walls.
