Changes in microbial (Bacteria and Archaea) plankton community structure after artificial dispersal in grazer-free microcosms [PDF]
, 2017 Microbes are considered to have a global distribution due to their high dispersal capabilities. However, our knowledge of the way geographically distant microbial communities assemble after dispersal in a new environment is limited.

At the core of the Archaea. [PDF]
Proceedings of the National Academy of Sciences, 1996 There are three kinds of taxonomists, according to Ernst Mayr (1). Pheneticists group species by overall phenotypic similarity, renouncing evolutionary theory and explanation. Cladists, conversely, concern themselves exclusively with genealogy. Phenotypic resemblance between two taxa (lizards and crocodiles as reptiles, for instance), counts for ...

Archaea, 2007 The gene‐dense chromosomes of archaea and bacteria were long thought to be devoid of pseudogenes, but with the massive increase in available genome sequences, whole genome comparisons between closely related species have identified mutations that have rendered numerous genes inactive.

Complex archaea that bridge the gap between prokaryotes and eukaryotes
Nature, 2015 The origin of the eukaryotic cell remains one of the most contentious puzzles in modern biology. Recent studies have provided support for the emergence of the eukaryotic host cell from within the archaeal domain of life, but the identity and nature of ...

SICLE: A high-throughput tool for extracting evolutionary relationships from phylogenetic trees
, 2016 We present the phylogeny analysis software SICLE (Sister Clade Extractor), an easy-to-use, high- throughput tool to describe the nearest neighbors to a node of interest in a phylogenetic tree as well as the support value for the relationship.

Current Biology, 1996 There's an old joke that circulates in newsrooms. A reporter rushes up to City Desk and breathlessly tells his editor that he has confirmed the Second Coming of Christ. The editor doesn't want the story. “We had that one already — 2 000 years ago.” If it's news, it has to be the first, the biggest, the oldest or the most, especially in science news. So,

Frontiers in Microbiology, 2020 The thermophilic archaeon Sulfolobus acidocaldarius can use different carbon sources for growth, including the pentoses D-xylose and L-arabinose. In this study, we identified the activator XylR (saci_2116) responsible for the transcriptional regulation ...

Nature Communications, 2018 Ammonia-oxidising archaea (AOA) are ubiquitous and abundant in nature and play a major role in nitrogen cycling. AOA have been studied intensively based on the amoA gene (encoding ammonia monooxygenase subunit A), making it the most sequenced functional ...

Ensambles de arqueas y bacterias en la Zona de Mínimo Oxígeno del ecosistema de surgencia de Chile central determinados mediante biomarcadores orgánicos [PDF]
, 2015 Indexación: Web of Science; Scielo.Organic biomarkers were used to investigate the influence of seasonal changes in oxygenation and water chemistry on the distribution of archaea and bacteria in the water column and surface sediments of the continental ...
