Archaeal evolution

Archaeal evolution is the process by which the domain of organisms called archaea has developed over multiple generations. This process can be studied by phylogenetics and such studies show that Archaea have a distinct evolutionary history from bacteria and eukaryotes.

    Metagenomics analyses of a hot spring in Yellowstone National Park reveal previously uncharacterized archaeal populations, including one with the genomic capacity to potentially couple anaerobic methane metabolism and dissimilatory sulfur reduction in a single organism.

    A search for methyl-coenzyme M reductase complex (MCR) and MCR-like homologues—which govern methane and short-chain alkane metabolism—across publicly available metagenomes reveals that these metabolic pathways are widespread and diverse in archaea, and may in some organisms be linked to alkane and/or fatty acid oxidation.

    Chemosynthetic microbial communities in hydrothermal environments receiving meteoric and geothermal fluids are understudied. Here, Colman et al. use metagenomics to study one such community from a hot spring at Yellowstone National Park, revealing exceptional biodiversity and unique functional potential.

    Methane metabolism has a central role in the global carbon cycle. In the Review, Tyson and colleagues discuss the enzymatic pathways responsible for archaeal methane metabolism and highlight the evolutionary relationships of key enzymes with recently discovered alkane-oxidizing archaea.

    Sulfolobus islandicus is a model organism within the TACK superphylum of the Archaea. Here, the authors perform a genome-wide analysis of essential genes in this organism, show that the proteinaceous S-layer is not essential, and explore potential stages of evolution of the essential gene repertoire in Archaea.
