Aquatic metagenomes implicate Thaumarchaeota in global cobalamin production [PDF]
The ISME Journal, 2014 Abstract Cobalamin (vitamin B12) is a complex metabolite and essential cofactor required by many branches of life, including most eukaryotic phytoplankton. Algae and other cobalamin auxotrophs rely on environmental cobalamin supplied from a relatively small set of cobalamin-producing prokaryotic taxa.

Insights into the Ecological Roles and Evolution of Methyl-Coenzyme M Reductase-Containing Hot Spring Archaea [PDF]
, 2019 Several recent studies have shown the presence of genes for the key enzyme associated with archaeal methane/alkane metabolism, methyl-coenzyme M reductase (Mcr), in metagenome-assembled genomes (MAGs) divergent to existing archaeal lineages.

Frontiers in Microbiology, 2019 Climate change is causing arctic regions to warm disproportionally faster than those at lower latitudes, leading to alterations in carbon and nitrogen cycling, and potentially higher greenhouse gas emissions.

Influence of soil properties on archaeal diversity and distribution in the McMurdo Dry Valleys, Antarctica [PDF]
, 2014 Archaea are the least understood members of the microbial community in Antarctic mineral soils. Although their occurrence in Antarctic coastal soils has been previously documented, little is known about their distribution in soils across the McMurdo Dry ...

The Thaumarchaeota: an emerging view of their phylogeny and ecophysiology
Current Opinion in Microbiology, 2011 Thaumarchaeota range among the most abundant archaea on Earth. Initially classified as 'mesophilic Crenarchaeota', comparative genomics has recently revealed that they form a separate and deep-branching phylum within the Archaea. This novel phylum comprises in 16S rRNA gene trees not only all known archaeal ammonia oxidizers but also several clusters ...

Global biodiversity of aquatic ammonia-oxidizing archaea is partitioned by habitat
Frontiers in Microbiology, 2012 Archaea play an important role in nitrification and are, thus, inextricably linked to the global carbon and nitrogen cycles. Since the initial discovery of an ammonia monooxygenase α-subunit (amoA) gene associated with an archaeal metagenomic fragment ...

Evidence of global-scale aeolian dispersal and endemism in isolated geothermal microbial communities of Antarctica [PDF]
, 2014 New evidence in aerobiology challenges the assumption that geographical isolation is an effective barrier to microbial transport. However, given the uncertainty with which aerobiological organisms are recruited into existing communities, the ultimate ...

Heterotrophic Thaumarchaeota with ultrasmall genomes are widespread in the ocean [PDF]
, 2020 Abstract The Thaumarchaeota comprise a diverse archaeal phylum including numerous lineages that play key roles in global biogeochemical cycling, particularly in the ocean. To date, all genomically-characterized marine Thaumarchaeota are reported to be chemolithoautotrophic ammonia-oxidizers.

Novel PCR primers for the archaeal phylum Thaumarchaeota designed based on the comparative analysis of 16S rRNA gene sequences. [PDF]
PLoS ONE, 2014 Based on comparative phylogenetic analysis of 16S rRNA gene sequences deposited in an RDP database, we constructed a local database of thaumarchaeotal 16S rRNA gene sequences and developed a novel PCR primer specific for the archaeal phylum ...
