Nanoarchaeota
Les Nanoarchaeota sont un embranchement (phylum) d'archées dont on ne connaît actuellement (1er juillet 2013) qu'une seule espèce : Nanoarchaeum equitans, qui, avec un diamètre de l'ordre de 400 nm, compte parmi les plus petites formes de vie connues.
Son statut de membre unique d'un embranchement à part entière est cependant débattu, car il pourrait en fait s'agir d'une espèce très spécialisée issue de l'ordre des Thermococcales, au sein de l'embranchement des Euryarchaeota.

Nanoarchaeota
"Insights into archaeal evolution and symbiosis from the genomes of a n" by Mircea Podar, Kira S. Makarova et al.
Background A single cultured marine organism, Nanoarchaeum equitans, represents the Nanoarchaeota branch of symbiotic Archaea, with a highly reduced genome and unusual features such as multiple split genes. Results The first terrestrial hyperthermophilic member of the Nanoarchaeota was collected from Obsidian Pool, a thermal feature in Yellowstone National Park, separated by single cell isolation, and sequenced together with its putative host, a Sulfolobales archaeon. Both the new Nanoarchaeota (Nst1) and N. equitans lack most biosynthetic capabilities, and phylogenetic analysis of ribosomal RNA and protein sequences indicates that the two form a deep-branching archaeal lineage. However, the Nst1 genome is more than 20% larger, and encodes a complete gluconeogenesis pathway as well as the full complement of archaeal flagellum proteins. With a larger genome, a smaller repertoire of split protein encoding genes and no split non-contiguous tRNAs, Nst1 appears to have experienced less severe genome reduction than N. equitans. These findings imply that, rather than representing ancestral characters, the extremely compact genomes and multiple split genes of Nanoarchaeota are derived characters associated with their symbiotic or parasitic lifestyle. The inferred host of Nst1 is potentially autotrophic, with a streamlined genome and simplified central and energetic metabolism as compared to other Sulfolobales. Conclusions 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. The two distinct Nanoarchaeota-host genomic data sets offer novel insights into the evolution of archaeal symbiosis and parasitism, enabling further studies of the cellular and molecular mechanisms of these relationships.

How to: bulk retrieval of archaeal genome sequences from the NCBI FTP site | What You're Doing Is Rather Desperate
While we're on the topic of mistaking Archaea for Bacteria, here's an issue with the NCBI FTP site that has long annoyed me and one workaround. Warning: I threw this together minutes ago and it's not fully tested. Let's cut to the chase. In the NCBI FTP site, archaeal genome data is stored along with…

Microorganisms; they are the most abundant form of life. They are all around us, silent, unseen and undetected.

Despite their abundance, we know very little about all but a small fraction of these diverse…

Latintos: Riding the fire sphere: Nanoarchaeum equitans
Nanoarchaeum equitans is one of the smallest living organisms known so far: a nano-sized (about 400 nm in diameter) microbe of the third domain, named archaea [1-4]. The epithet equitans relates to the Latin nouns equus and equitatus, meaning “horse” and “horse riding,” respectively.

Biology Direct | Full text | Updated clusters of orthologous genes for Archaea: a complex ancestor of the Archaea and the byways of horizontal gene transfer
Collections of Clusters of Orthologous Genes (COGs) provide indispensable tools for comparative genomic analysis, evolutionary reconstruction and functional annotation of new genomes. Initially, COGs were made for all complete genomes of cellular life forms that were available at the time. However, with the accumulation of thousands of complete genomes, construction of a comprehensive COG set has become extremely computationally demanding and prone to error propagation, necessitating the switch to taxon-specific COG collections. Previously, we reported the collection of COGs for 41 genomes of Archaea (arCOGs). Here we present a major update of the arCOGs and describe evolutionary reconstructions to reveal general trends in the evolution of Archaea.
