Novel insights into the Thaumarchaeota in the deepest oceans: their metabolism and potential adaptation mechanisms [PDF]
Background Marine Group I (MGI) Thaumarchaeota, which play key roles in the global biogeochemical cycling of nitrogen and carbon (ammonia oxidizers), thrive in the aphotic deep sea with massive populations.

Gene duplication drives genome expansion in a major lineage of Thaumarchaeota [PDF]
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.

Comparative Genomics Reveals Ecological and Evolutionary Insights into Sponge-Associated
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.

Accu16S/AccuITS: Accurate and broadly applicable amplicon sequencing for absolute microbiome quantification. [PDF]
Traditional 16S rRNA gene and Internal Transcribed Spacer region amplicon sequencing provides only relative abundance, often leading to biased ecological interpretations. To overcome this limitation, we developed Accu16S/AccuITS, an absolute quantification method for bacterial and fungal amplicons based on synthetic internal spike‐in DNA with known ...

Spotlight on the Thaumarchaeota [PDF]
Over the last two decades, many new groups of deeply branching uncultivated archaea have been unveiled by molecular screening of 16S rRNA genes. Among these, Thaumarchaeota (Brochier-Armanet et al., 2008) are now known to represent a highly diversified and ancient phylum present in a wide variety of ecosystems, including marine and fresh waters, soils ...

Integrated mobile genetic elements in Thaumarchaeota [PDF]
Summary To explore the diversity of mobile genetic elements (MGE) associated with archaea of the phylum Thaumarchaeota, we exploited the property of most MGE to integrate into the genomes of their hosts. Integrated MGE (iMGE) were identified in 20 thaumarchaeal genomes amounting to 2 Mbp of mobile thaumarchaeal ...

Planktonic Archaeal Ether Lipid Origins in Surface Waters of the North Pacific Subtropical Gyre
Thaumarchaeota and Thermoplasmatota are the most abundant planktonic archaea in the sea. Thaumarchaeota contain tetraether lipids as their major membrane lipids, but the lipid composition of uncultured planktonic Thermoplasmatota representatives remains ...

Phylogenetic congruence and ecological coherence in terrestrial Thaumarchaeota [PDF]
Abstract Thaumarchaeota form a ubiquitously distributed archaeal phylum, comprising both the ammonia-oxidising archaea (AOA) and other archaeal groups in which ammonia oxidation has not been demonstrated (including Group 1.1c and Group 1.3).

Background Thaumarchaeota are abundant in the Amazon River, where they are the only ammonia-oxidizing archaea. Despite the importance of Thaumarchaeota, little is known about their physiology, mainly because few isolates are available for study ...

Nitrification is a vital ecosystem function in the open ocean that regenerates inorganic nitrogen and promotes primary production. Recent studies have shown that the ecology and physiology of nitrifying organisms is more complex than previously ...
