Molecular signatures for the Crenarchaeota and the Thaumarchaeota

Antonie Van Leeuwenhoek, 2010
Crenarchaeotes found in mesophilic marine environments were recently placed into a new phylum of Archaea called the Thaumarchaeota. However, very few molecular characteristics of this new phylum are currently known which can be used to distinguish them from the Crenarchaeota.

Coupling of diversification and pH adaptation during the evolution of terrestrial Thaumarchaeota [PDF]

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2015
Significance The link between species diversification and adaptation has long interested biologists working on multicellular eukaryotes, but remains poorly understood in prokaryotes, in which diversity is much greater. We tested the hypothesis that diversification is associated with environmental adaptation in Thaumarchaeota, an ancient and ...

Cyanate and urea are substrates for nitrification by Thaumarchaeota in the marine environment [PDF]

open access: yesNature Microbiology, 2018
Ammonia-oxidizing archaea of the phylum Thaumarchaeota are among the most abundant marine microorganisms1. These organisms thrive in the oceans despite ammonium being present at low nanomolar concentrations2,3. Some Thaumarchaeota isolates have been shown to utilize urea and cyanate as energy and N sources through intracellular conversion to ammonium4 ...

Single-cell genomics shedding light on marine Thaumarchaeota diversification [PDF]

open access: yesISME Journal, 2013
Abstract Previous studies based on analysis of amoA, 16S ribosomal RNA or accA gene sequences have established that marine Thaumarchaeota fall into two phylogenetically distinct groups corresponding to shallow- and deep-water clades, but it is not clear how water depth interacts with other environmental factors, including light ...

The Phylum Thaumarchaeota

2014
Thaumarchaeota represent a unique phylum within the domain Archaea that embraces ammonia-oxidizing organisms from soil, marine waters, and hot springs (currently two pure cultures and 13 enrichments), as well as many lineages represented only by environmental sequences from virtually every abitat that has been screened.

Mesophilic crenarchaeota: proposal for a third archaeal phylum, the Thaumarchaeota

Nature Reviews Microbiology, 2008
The archaeal domain is currently divided into two major phyla, the Euryarchaeota and Crenarchaeota. During the past few years, diverse groups of uncultivated mesophilic archaea have been discovered and affiliated with the Crenarchaeota. It was recently recognized that these archaea have a major role in geochemical cycles.
