Genome-resolved metagenomics analysis provides insights into the ecological role of Thaumarchaeota in the Amazon River and its plume

BMC Microbiology, 2020
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 ...

Accu16S/AccuITS: Accurate and broadly applicable amplicon sequencing for absolute microbiome quantification. [PDF]

Imeta
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 ...

Data_Sheet_2_Comparative Genomics of Thaumarchaeota From Deep-Sea Sponges Reveal Their Niche Adaptation.xlsx

, 2022
Thaumarchaeota account for a large portion of microbial symbionts in deep-sea sponges and are even dominant in some cases. In this study, we investigated three new sponge-associated Thaumarchaeota from the deep West Pacific Ocean.

Depth Profile of Nitrifying Archaeal and Bacterial Communities in the Remote Oligotrophic Waters of the North Pacific

Frontiers in Microbiology, 2021
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 ...

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.

Ammonia Oxidation by the Arctic Terrestrial Thaumarchaeote Candidatus Nitrosocosmicus arcticus Is Stimulated by Increasing Temperatures

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.

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 ...

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 ...
