Lokiarchaea are close relatives of Euryarchaeota, not bridging the gap between prokaryotes and eukaryotes.

PLoS Genetics, 2017
The eocyte hypothesis, in which Eukarya emerged from within Archaea, has been boosted by the description of a new candidate archaeal phylum, "Lokiarchaeota", from metagenomic data.

Distribution, abundance, and diversity patterns of the thermoacidophilic Deep-sea Hydrothermal Vent Euryarchaeota 2 (DHVE2). [PDF]

Frontiers in Microbiology, 2012
Cultivation-independent studies have shown that taxa belonging to the Deep-sea Hydrothermal Vent Euryarchaeota 2 (DHVE2) lineage are widespread at deep-sea hydrothermal vents.

A moderately thermophilic origin of a novel family of marine group II euryarchaeota from deep ocean

iScience, 2023
Summary: Marine group II (MGII) is the most abundant planktonic heterotrophic archaea in the ocean. The evolutionary history of MGII archaea is elusive. In this study, 13 new MGII metagenome-assembled genomes were recovered from surface to the hadal zone

Replication slippage of the thermophilic DNA polymerases B and D from the Euryarchaeota Pyrococcus abyssi [PDF]

Frontiers in Microbiology, 2014
Replication slippage or slipped-strand mispairing involves the misalignment of DNA strands during the replication of repeated DNA sequences, and can lead to genetic rearrangements such as microsatellite instability.

Detection of Euryarchaeota and Crenarchaeota in an oxic basalt aquifer [PDF]

FEMS Microbiology Ecology, 2003
Groundwater from an oxic, fractured basalt aquifer was examined for the presence of Archaea. DNA was extracted from cells concentrated from groundwater collected from five wells penetrating the eastern Snake River Plain Aquifer (Idaho, USA). Polymerase chain reaction (PCR) amplification of 16S rDNA was performed with Archaea-specific primers using both

The Discussion Goes on: What Is the Role ofEuryarchaeotain Humans? [PDF]

Archaea, 2010
The human body (primarily the intestinal tract, the oral cavity, and the skin) harbours approximately 1,000 different bacterial species. However, the number of archaeal species known to colonize man seems to be confined to a handful of organisms within the classEuryarchaeota(includingMethanobrevibacter smithii,M.

Crenarchaeota and Euryarchaeota in temperate estuarine sediments [PDF]

Journal of Applied Microbiology, 2001
Application of molecular techniques to ecological studies has unveiled a wide diversity of micro-organisms in natural communities, previously unknown to microbial ecologists. New lineages of Archaea were retrieved from several non-extreme environments, showing that these micro-organisms are present in a large variety of ecosystems.

Isolation of a methyl-reducing methanogen outside the Euryarchaeota

Goldschmidt2023 abstracts, 2023
Abstract Methanogenic archaea are main contributors to methane emissions, and thus play a crucial role in carbon cycling and global warming. Until recently, methanogens were confined to the phylum Euryarchaeota, but metagenomic studies revealed the presence of genes encoding the methyl coenzyme M reductase complex in other archaeal clades ...

Study of cattle microbiota in different regions of Kazakhstan using 16S metabarcoding analysis

Scientific Reports, 2022
Methane (CH4) is an important greenhouse gas (GHG). Enteric methane emissions from farmed ruminant livestock account for approximately 15% of global GHG emissions, with approximately 44% of livestock emissions in the form of methane.

Bacterial and Archaeal Water and Sediment Communities of Two Hot Spring Streams in Tengchong, Yunnan Province, China

Diversity, 2022
In Tengchong County, springs with wide physicochemical diversity provide a multitude of niches for extremophilic microorganisms. In this study, eight middle-low temperature spring sites along two continuous small streams with low water flow and slow ...
