2017年8月4日 · Hereafter, we will present an overview of some of the most significant recent findings, which are discussed based on an updated robust phylogeny of the Archaea obtained from a large taxonomic...

2019年12月2日 · Our trees indicate remarkably closer evolutionary proximity between Archaea and Bacteria than previous estimates that were limited to fewer “core” genes, such as the ribosomal proteins.

Phylogenetic tree showing the relationship between the Archaea and other domains of life. Eukaryotes are colored red, archaea green and bacteria blue. Adapted from Ciccarelli et al. (2006) [80] The relationships among the three domains are of central importance for understanding the origin of life.

Archaea, a principal third branch of the phylogenetic tree, were unexpectedly discovered in 1976/77 during Woese’s bacterial molecular taxonomy project. This section describes this discovery, the controversy that it raised, and early phases of its substantiation and acceptance up to the early 1990s.

Phylogenomics analyses of the components of different molecular systems are highlighting a core of mainly vertically inherited genes in Archaea. This allows recovering a globally well-resolved picture of archaeal evolution, as opposed to what is observed for Bacteria and Eukarya.

2017年8月11日 · This phylogenetic tree depicts the diversity of the key enzyme (Mcr) for methanogenesis (taxa shaded in blue) and anaerobic methane oxidation (taxa shaded in green), which was recently also implicated in the oxidation of butane in …

2022年1月5日 · Beyond the specifics of archaeal phylogeny, our results demonstrate the power of divide-and-conquer approaches to resolve deep phylogenetic relationships, which should be applied to progressively resolve the entire Tree of Life.

2020年5月4日 · In this Review, we discuss how these genomes, together with long-term enrichment studies and elegant in situ measurements, are providing insights into the metabolic capabilities of the Archaea.

In this paper, we study Archaea phylogeny across many phyla. This is distinct from the phylogeny of species in a narrow range of taxa, e.g., that of vertebrates (a subphylum) or human versus close relatives (a few genera).
