Spatiotemporal Dynamics of Ammonia-Oxidizing Thaumarchaeota in Distinct Arctic Water Masses [PDF]
Frontiers in Microbiology, 2018 One of the most abundant archaeal groups on Earth is the Thaumarchaeota. They are recognized as major contributors to marine ammonia oxidation, a crucial step in the biogeochemical cycling of nitrogen.

Metagenomic characterization of a novel non-ammonia-oxidizing Thaumarchaeota from hadal sediment [PDF]
MicrobiomeBackground The hadal sediment, found at an ocean depth of more than 6000 m, is geographically isolated and under extremely high hydrostatic pressure, resulting in a unique ecosystem.

Horizontal gene transfer of a chloroplast DnaJ-Fer protein to Thaumarchaeota and the evolutionary history of the DnaK chaperone system in Archaea [PDF]
BMC Evolutionary Biology, 2012 Background In 2004, we discovered an atypical protein in metagenomic data from marine thaumarchaeotal species. This protein, referred as DnaJ-Fer, is composed of a J domain fused to a Ferredoxin (Fer) domain. Surprisingly, the same protein was also found

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.

Molecular and Isotopic Investigations Into the Ecology of Marine Thaumarchaeota
, 2018 Ammonia-oxidizing Archaea affiliated with phylum Thaumarchaeota are among the most abundant microorganisms in the global oceans and are generally recognized as the drivers of marine nitrification.

Gene duplication drives genome expansion in a major lineage of Thaumarchaeota [PDF]
Nature Communications, 2020 Ammonia-oxidising archaea of the phylum Thaumarchaeota are important organisms in the nitrogen cycle. Using 12 new genomes, this study finds evidence that Nitrososphaerales evolution was marked by lateral gene transfer followed by gene duplication.

Expansion of Thaumarchaeota habitat range is correlated with horizontal transfer of ATPase operons [PDF]
The ISME Journal, 2019 Thaumarchaeota are responsible for a significant fraction of ammonia oxidation in the oceans and in soils that range from alkaline to acidic. However, the adaptive mechanisms underpinning their habitat expansion remain poorly understood.

Comparative Genomics Reveals Ecological and Evolutionary Insights into Sponge-Associated
mSystems, 2019 Thaumarchaeota are frequently reported to associate with marine sponges (phylum Porifera); however, little is known about the features that distinguish them from their free-living thaumarchaeal counterparts.
