According to small subunit ribosomal RNA (ss rRNA) sequence comparisons all known Archaea belong to the phyla Crenarchaeota, Euryarchaeota, and—indicated only by environmental DNA sequences—to the ‘Korarchaeota’. Here we report the cultivation of a new nanosized hyperthermophilic archaeon from a submarine hot vent. This archaeon cannot be attached to one of these groups and therefore must represent an unknown phylum which we name ‘Nanoarchaeota’ and species, which we name ‘Nanoarchaeum equitans… Expand

Nanoarchaea: representatives of a novel archaeal phylum or a fast-evolving euryarchaeal lineage related to Thermococcales?
TLDR
It is indicated that the placement of N. equitans in archaeal phylogenies on the basis of ribosomal protein concatenation may be strongly biased by the coupled effect of its above-average evolutionary rate and lateral gene transfers. Expand
The genome of Nanoarchaeum equitans: Insights into early archaeal evolution and derived parasitism
TLDR
The hyperthermophile Nanoarchaeum equitans is an obligate symbiont growing in coculture with the crenarchaeon Ignicoccus, and represents a basal archaeal lineage and has a highly reduced genome. Expand
Insights into archaeal evolution and symbiosis from the genomes of a nanoarchaeon and its inferred crenarchaeal host from Obsidian Pool, Yellowstone National Park
TLDR
Comparison of the N. equitans and Nst1 genomes suggests that the marine and terrestrial lineages of Nanoarchaeota share a common ancestor that was already a symbiont of another archaeon, enabling further studies of the cellular and molecular mechanisms of these relationships. Expand
First description of giant Archaea (Thaumarchaeota) associated with putative bacterial ectosymbionts in a sulfidic marine habitat.
TLDR
Two new giantarchaeal species are described that form the biggest archaeal filaments ever observed and an unexpected morphological and genetic diversity of the phylum Thaumarchaeota is highlighted. Expand
The Korarchaeota: Archaeal orphans representing an ancestral lineage of life
TLDR
The cultivation and initial characterization of the first member of the Korarchaeota is described, highly unusual, ultrathin filamentous cells about 0.16 {micro}m in diameter, which likely diverged near the separation of the two major kingdoms of Archaea. Expand
Nanoarchaeal 16S rRNA gene sequences are widely dispersed in hyperthermophilic and mesophilic halophilic environments
TLDR
The results suggest that nanoarchaeotes are not strictly hyperthermophilic organisms, are not restricted to hyperthernophilic hosts and may be found in a large range of environmental conditions. Expand
Expanding Metabolic Diversity of Two Archaeal Phyla: Nanoarchaeota and Korarchaeota
TLDR
Two metagenomic studies presented in this thesis identified which samples could be prioritized for genome reconstruction of uncultured bacterial and archaeal lineages and identified many unculturing deep-sea hydrothermal archaealing lineages. Expand
Insights into the evolution of Archaea and eukaryotic protein modifier systems revealed by the genome of a novel archaeal group
TLDR
The genome sequence of Candidatus ‘Caldiarchaeum subterraneum’ is shown that represents an uncultivated crenarchaeotic group and indicates that a prototype of the eukaryotic protein modifier system is present in the Archaea. Expand
Uncultured Archaea in a hydrothermal microbial assemblage: phylogenetic diversity and characterization of a genome fragment from a euryarchaeote.
TLDR
This study is the first step in using genomics to reveal the physiology of an as yet uncultured group of archaea from deep-sea hydrothermal vents. Expand
Metabolic Diversity and Evolutionary History of the Archaeal Phylum “Candidatus Micrarchaeota” Uncovered from a Freshwater Lake Metagenome
TLDR
The recently described superphylum DPANN includes several phyla of uncultivated archaea with small cell sizes, reduced genomes, and limited metabolic capabilities, and a complete genome of “Ca. Micrarchaeota” is reported, revealing the presence of metabolic capacities lost in ARMAN genomes that could enable a free-living lifestyle. Expand

Remarkable archaeal diversity detected in a Yellowstone National Park hot spring environment.
TLDR
The large number of distinct archaeal sequence types retrieved from this single hot spring was unexpected and demonstrates that Crenarchaeota is a much more diverse group than was previously suspected. Expand

A psychrophilic crenarchaeon inhabits a marine sponge: Cenarchaeum symbiosum gen. nov., sp. nov.
TLDR
The discovery and preliminary characterization of a marine archaeon that inhabits the tissues of a temperate water sponge and represents the first described symbiosis involving Crenarchaeota, and a symbiotic archaeon closely related to other nonthermophilic cren archaeotes that inhabit diverse marine and terrestrial environments is presented.

Isolation of a hyperthermophilic archaeum predicted by in situ RNA analysis
TLDR
A procedure to obtain pure cultures of unknown organisms harbouring specific 16S rRNA sequences identified previously within the environment is described, which validates polymerase chain reaction data on the existence of large archaeal communities. Expand
Ignicoccus gen. nov., a novel genus of hyperthermophilic, chemolithoautotrophic Archaea, represented by two new species, Ignicoccus islandicus sp nov and Ignicoccus pacificus sp nov. and Ignicoccus pacificus sp. nov.
TLDR
Two species of novel, chemolithoautotrophic, sulfidogenic micro-organisms were isolated from submarine hydrothermal systems in the Atlantic and Pacific and revealed that they are members of the crenarchaeal branch of the Archaea, representing a new, deeply branching lineage within the family of the Desulfurococcaceae.

Towards a natural system of organisms: proposal for the domains Archaea, Bacteria, and Eucarya.
TLDR
It is proposed that a formal system of organisms be established in which above the level of kingdom there exists a new taxon called a "domain." Life on this planet would be seen as comprising three domains, the Bacteria, the Archaea, and the Eucarya, each containing two or more kingdoms. Expand

Bacterial phylogeny based on comparative sequence analysis (review)
TLDR
It is shown that only careful data analysis starting with a proper alignment, followed by the analysis of positional variability, rates and character of change, testing various data selections, applying alternative treeing methods and, finally, performing confidence tests, allows reasonable utilization of the limited phylogenetic information.
