TY - JOUR. T1 - Cultivation of mesophilic soil crenarchaeotes in enrichment cultures from plant roots. AU - Simon, Holly M.. AU - Jahn, Courtney E.. AU - Bergerud, Luke T.. AU - Sliwinski, Marek K.. AU - Weimer, Paul J.. AU - Willis, David K.. AU - Goodman, Robert M.. PY - 2005/8. Y1 - 2005/8. N2 - Because archaea are generally associated with extreme environments, detection of nonthermophilic members belonging to the archaeal division Crenarchaeota over the last decade was unexpected; they are surprisingly ubiquitous and abundant in nonextreme marine and terrestrial habitats. Metabolic characterization of these nonthermophilic crenarchaeotes has been impeded by their intractability toward isolation and growth in culture. From studies employing a combination of cultivation and molecular phylogenetic techniques (PCR-single-strand conformation polymorphism, sequence analysis of 16S rRNA genes, fluorescence in situ hybridization, and real-time PCR), we present evidence here that one of the two ...
The Miscellaneous Crenarchaeotic Group (MCG) is an archaeal lineage whose members are widespread and abundant in marine sediments. MCG archaea have also been consistently found in stratified euxinic lakes. In this work, we have studied archaeal communities in three karstic lakes to reveal potential habitat segregation of MCG subgroups between planktonic and sediment compartments. In the studied lakes, archaeal assemblages were strikingly similar to those of the marine subsurface with predominance of uncultured Halobacteria in the plankton and Thermoplasmata and MCG in anoxic, organic-rich sediments. Multivariate analyses identified sulphide and dissolved organic carbon as predictor variables of archaeal community composition. Quantification of MCG using a newly designed qPCR primer pair that improves coverage for MCG subgroups prevalent in the studied lakes revealed conspicuous populations in both the plankton and the sediment. Subgroups MCG-5a and -5b appear as planktonic specialists thriving ...
Terpenoids, also known as isoprenoids, are a large class of natural products consisting of isoprene (C5) units. There are two biosynthetic pathways, the mevalonate pathway [MD:M00095] and the non-mevalonate pathway or the MEP/DOXP pathway [MD:M00096], for the terpenoid building blocks: isopentenyl diphosphate (IPP) and dimethylallyl diphosphate (DMAPP). The action of prenyltransferases then generates higher-order building blocks: geranyl diphosphate (GPP), farsenyl diphosphate (FPP), and geranylgeranyl diphosphate (GGPP), which are the precursors of monoterpenoids (C10), sesquiterpenoids (C15), and diterpenoids (C20), respectively. Condensation of these building blocks gives rise to the precursors of sterols (C30) and carotenoids (C40). The MEP/DOXP pathway is absent in higher animals and fungi, but in green plants the MEP/DOXP and mevalonate pathways co-exist in separate cellular compartments. The MEP/DOXP pathway, operating in the plastids, is responsible for the formation of essential oil ...

A gene for membrane-integral inorganic pyrophosphatase (miPPase) was found in the composite genome of the extremophile archaeon Candidatus Korarchaeum cryptofilum (CKc). This korarchaeal genome shows unusual partial similarity to both major archaeal phyla Crenarchaeota and Euryarchaeota. Thus this Korarchaeote might have retained features that represent an ancestral archaeal form, existing before the occurrence of the evolutionary bifurcation into Crenarchaeota and Euryarchaeota. In addition, CKc lacks five genes that are common to early genomes at the LUCA border. These two properties independently suggest a pre-LUCA evolutionary position of this extremophile. Our finding of the miPPase gene in the CKc genome points to a role for the enzyme in the energy conversion of this very early archaeon. The structural features of its miPPase indicate that it can pump protons through membranes. An miPPase from the extremophile bacterium Caldicellulosiruptor saccharolyticus also has a sequence indicating a ...

To search for genetic clues to carbon and energy metabolism in Crenarchaeota, the researchers extracted C. symbiosum DNA from its host sponge and constructed a DNA library for sequencing the symbiont s genome. Hallam et al. then searched for representative genes linked to pathways associated with autotrophic carbon assimilation. They found many components of two pathways: the 3-hydroxypropionate cycle and the reductive tricarboxylic acid (citric acid) pathway (TCA). Both cycles involve a multistep series of chemical reactions that convert inorganic compounds in this case, carbon dioxide into organic carbon molecules. Though some components of the 3-hydroxypropionate cycle were missing in C. symbiosum, enough elements (including core proteins) were found to support a modified version of this pathway for carbon assimilation, using carbon dioxide ...
In constrast to bacteria, all archaea possess cell walls lacking peptidoglycan and a number of different cell envelope components have also been described. A paracrystalline protein surface layer, commonly referred to as S-layer, is present in nearly all archaea described to date. S-layers are composed of only one or two proteins and form different lattice structures. In this review, we summarise current understanding of archaeal S-layer proteins, discussing topics such as structure, lattice type distribution among archaeal phyla and glycosylation. The hexagonal lattice type is dominant within the phylum Euryarchaeota, while in the Crenarchaeota this feature is mainly associated with specific orders. S-layers exclusive to the Crenarchaeota have also been described, which are composed of two proteins. Information regarding S-layers in the remaining archaeal phyla is limited, mainly due to organism description through only culture-independent methods. Despite the numerous applied studies using bacterial S
The Fisheries Society of the British Isles awarded the 2017 Le Cren Medal to FishBase for a lifelong contribution to all aspects of the study of fish biology and/or fisheries science, with a focus on conservation, training or public understanding of the discipline.. In a ceremony held on July 6, 2017 in Exeter, United Kingdom as part of the FSBI 50th Anniversary, long-term FishBase coordinator and Senior Scientist at Geomar Helmholtz-Zentrum für Ozeanforschung Kiel, Dr. Rainer Froese, received the award from the President of the FSBI, Dr. Iain Barber.. As he presented FishBase with the honour, Dr. Barber highlighted the importance of having a database that gathers and provides information on more than 33,000 species and that is maintained by an international team of experts.. The Le Cren Medal is inspired by E. David Le Cren, a fisheries biologist who wrote in 1951 the citation classic The length-weight relationship and seasonal cycle in gonad weight and condition in the perch (Perca ...

AU - Treusch, Alexander H. AU - Meurer, Guido. AU - Eck, Jürgen. AU - Sensen, Christoph W. AU - Schleper, Christa. PY - 2002. Y1 - 2002. N2 - Molecular phylogenetic surveys based on the characterization of 16S rRNA genes have revealed that soil is an environment particularly rich in microbial diversity. A clade of crenarchaeota (archaea) has frequently been detected among many other novel lineages of uncultivated bacteria. In this study we have initiated a genomic approach for the characterization of uncultivated microorganisms from soil. We have developed a procedure based on a two-phase electrophoresis technique that allows the fast and reliable purification of concentrated and clonable, high molecular weight DNA. From this DNA we have constructed complex large-insert genomic libraries. Using archaea-specific ...

Klasifikace archeí je i dnes neustále v pohybu. Současné systémy se snaží seskupovat organismy na základě jejich skutečné příbuznosti.[13] Velkou roli v systematice hrají sekvence genů pro ribozomální RNA, díky nimž lze příbuzenské vztahy odhalit.[14] Většina z těch nejznámějších archeí se dnes řadí do dvou kmenů, Euryarchaeota a Crenarchaeota. Přesto existují a jsou nadále objevovány i další kmeny, například druh Nanoarchaeum equitans, objevený v roce 2003, je klasifikován v samostatném kmeni Nanoarchaeota.[15] Pro hrstku neobvyklých termofilních archeí se zase zavedl kmen Korarchaeota.[16][17] Podobně byl pro druhy Nitrosopumilus maritimus, Cenarchaeum symbiosum a příbuzná mezofilní archaea zaveden kmen Thaumarchaeota.[18] Sekvenování archeálních genomů přineslo objevy dalších odlišných linií: V roce 2011 byl navržen nový kmen Aigararchaeota pro archeum Caldiarchaeum subterraneum, nalezené v geotermálních vodách v podzemním ...
A metaproteomic survey of surface coastal waters near Palmer Station on the Antarctic Peninsula, West Antarctica, was performed, revealing marked differences in the functional capacity of summer and winter communities of bacterioplankton. Proteins from Flavobacteria were more abundant in the summer metaproteome, whereas winter was characterized by proteins from ammonia-oxidizing Marine Group I Crenarchaeota. Proteins prevalent in both seasons were from SAR11 and Rhodobacterales clades of Alphaproteobacteria, as well as many lineages of Gammaproteobacteria. The metaproteome data were used to elucidate the main metabolic and energy generation pathways and transport processes occurring at the microbial level in each season. In summer, autotrophic carbon assimilation appears to be driven by oxygenic photoautotrophy, consistent with high light availability and intensity. In contrast, during the dark polar winter, the metaproteome supported the occurrence of chemolithoautotrophy via the ...

Os korarqueotas (Korarchaeota) son un filo de arqueas.[1] O nome procede do xénero principal do grupo Korarchaeum. Tamén se lles ten chamado Xenarchaea e Xenarchaeota.. Foron descubertas a partir de mostras de secuencias xenómicas de ARNr de 16S recollidas en ambientes naturais e non se puideron cultivar. As Korarchaeota só se atoparon en ambientes hidrotermais de altas temperaturas. Parece que se diversificaron a diferentes niveis filoxenéticos de acordo coa temperatura, salinidade das augas, e xeografía.[2] Son pouco abundantes na natureza.[2][3][4] Os procesos metabólicos de Korarchaeota, incluíndo como conseguen enerxía e obteñen o carbono, son descoñecidos. A análise das súas secuencias de ARNr de 16 S suxire que estas especies non forman parte dos dous principais grupos de arqueas, Crenarchaeota e Euryarchaeota [5]. Parece que son un grupo basal de arqueas, xa que teñen cracterísitcas tanto de Crenarchaeota coma de Euryarchaeota. O xenoma de Korarchaeum cryptofilum, que foi ...

As Archaea ou arqueas (do grego ἀρχαῖα os antigos) son un grupo de microorganismos unicelulares de morfoloxía procariótica (sen núcleo nin, en xeral, orgánulos membranosos internos), que forman un dos tres grandes dominios dos seres vivos, e que son diferentes das bacterias..

Diversity, distribution and genetic comparison of Archaea associated with the surface mucus of corals from three genera, namely Acanthastrea sp., Favia sp. and Fungia sp., from the Gulf of Eilat, Israel and from Heron Island, Australia were studied. Sequencing of the 16S rRNA gene of the coral-associated Archaea revealed dominance of Crenarchaeota (79%, on average). In this phylum, 87% of the sequences were similar (,or= 97%) to the Thermoprotei, with 76% of these being similar (,or= 97%) to the ammonium oxidizer, Nitrosopumilus maritimus. Most of the coral-associated euryarchaeotal sequences (69%) were related to marine group II, while other euryarchaeotal clades were found to be related to anaerobic methanotrophs (8%), anaerobic nitrate reducers (i.e. denitrification, 15%) and marine group III (8%). Most of the crenarchaeotal and euryarchaeotal coral-associated 16S rRNA gene sequences from Heron Island (61%) and from the Gulf of Eilat (71%) were closely related (,or= 97%) to sequences ...

Previous studies demonstrated that the diversity and composition of respiratory microbiota in TB patients were different from healthy individuals. Therefore, the aim of the present analysis was to estimate the relative proportion of respiratory microbiota at phylum and genus levels among TB cases and healthy controls. The PubMed and Google Scholar online databases were searched to retrieve relevant studies for the analysis. The statistical analysis was done using STATA version 11, pooled estimates are presented using graphs. The summary of findings in included studies is also presented in Table 1. The phylum level analysis shows that the pooled proportions of Firmicutes, Proteobacteria, Bacteroidetes, Actinobacteria, and Crenarchaeota were determined among tuberculosis patients and healthy controls. In brief, Firmicutes, and Proteobacteria were the most abundant bacterial phyla in both TB cases and healthy controls, composing 39.9 and 22.7% in TB cases and 39.4 and 19.5% in healthy controls,

Available genome sequences of AOA indicate that numerous Cu-dependent enzymes are essential for both ammonia oxidation and electron transfer, suggesting a particularly high requirement for copper. However, our knowledge of the copper requirements of AOA and their response to copper limitation in the ocean is nonexistent. Here, we examine the copper requirements of the chemolithoautotrophic AOA Candidatus Nitrosopumilus maritimus SCM1 ...
In taxonomy, the Korarchaeota are a phylum of the Archaea. The name is derived from the Greek noun koros or kore, meaning young man or young woman, and the Greek adjective archaios which means ancient. They are also known as Xenarchaeota. Korarchaeota is regarded as a phylum, which itself is part of the archaeal TACK superphylum which encompasses Thaumarchaeota, Aigarchaeota, Crenarchaeota and Korarchaeota. Analysis of their 16S rRNA gene sequences suggests that they are a deeply branching lineage that does not belong to the main archaeal groups, Crenarchaeota and Euryarchaeota. Analysis of the genome of one korarchaeote that was enriched from a mixed culture revealed a number of both Crenarchaeota- and Euryarchaeota-like features and supports the hypothesis of a deep-branching ancestry. The strain Korarchaeum cryptofilum was cultivated in an enrichment culture from a hot spring in Yellowstone National Park in USA 2008. The cells are long and needleshaped, which gave the species its ...

An evolutionary classification of genes from sequenced genomes that distinguishes between orthologs and paralogs is indispensable for genome annotation and evolutionary reconstruction. Shortly after multiple genome sequences of bacteria, archaea, and unicellular eukaryotes became available, an attempt on such a classification was implemented in Clusters of Orthologous Groups of proteins (COGs). Rapid accumulation of genome sequences creates opportunities for refining COGs but also represents a challenge because of error amplification. One of the practical strategies involves construction of refined COGs for phylogenetically compact subsets of genomes. New Archaeal Clusters of Orthologous Genes (arCOGs) were constructed for 41 archaeal genomes (13 Crenarchaeota, 27 Euryarchaeota and one Nanoarchaeon) using an improved procedure that employs a similarity tree between smaller, group-specific clusters, semi-automatically partitions orthology domains in multidomain proteins, and uses profile searches for

T1 - Perspectives on archaeal diversity, thermophily and monophyly from environmental rRNA sequences. PY - 1996 UR - http://www.pnas.org/content/93/17/9188.abstract N2 - Phylogenetic analysis of ribosomal RNA sequences obtained from uncultivated organisms of a hot spring in Yellowstone National Park reveals several novel groups of Archaea, many of which diverged from the crenarchaeal line of descent prior to previously characterized members of that kingdom. Universal phylogenetic trees constructed with the addition of these sequences indicate monophyly of Archaea, with modest bootstrap support. The data also show a specific relationship between low-temperature marine Archaea and some hot spring Archaea. Two of the environmental sequences are enigmatic: depending upon the dataset and analytical method used, these sequences branch deeply within the Crenarchaeota, below the bifurcation ...
Archaea are divided into two main groups based on rRNA trees, the Euryarchaeota and Crenarchaeota. Two other groups have been tentatively created for certain environmental samples and the peculiar species Nanoarchaeum equitans, discovered in 2002 by Karl Stetter, but their affinities are uncertain. Woese argued that the bacteria, archaea, and eukaryotes each represent a primary line of descent that diverged early on from an ancestral progenote with poorly developed genetic machinery. This hypothesis is reflected in the name Archaea, from the Greek archae or ancient. Later he treated these groups formally as domains, each comprising several kingdoms. This division has become very popular, although the idea of the progenote itself is not generally supported. Some biologists, however, have argued that the archaebacteria and eukaryotes arose from specialized eubacteria. The relationship between Archaea and Eukarya remains an important problem. Aside from the similarities noted above, many genetic ...
Before genomics techniques, the dark ocean was a black box, because microorganisms from this environment refuse to grow in research laboratories, said Ramunas Stepanauskas, a senior research scientist at Bigelow Laboratory and director of the Single Cell Genomics Center. Now, using contemporary tools that were developed by our group, we can open this black box and understand who is living there, what they are doing, and how they are doing it.. The research behind this Science paper began with an effort to identify new groups of microscopic organisms in the mesopelagic zone. According to Pachiadaki, the previously accepted explanation for carbon capture in the dark ocean did not seem correct under close inspection. Archaea, a much more abundant group of microorganisms in the dark ocean, had been credited with doing most of the work, but the math just didnt add up. The team set out to discover the unidentified organisms that were the true champions of carbon dioxide capture in the vast dark ...

In recent years several laboratories have developed effective plating techniques, identifying genetic markers that do not target cell wall synthesis, fusing archaeal promoters with recombinant genes, and isolating native vectors and promiscuous nonnative vectors. This chapter focuses on tractable systems that are currently available for the Archaea. Due to fundamental differences between gene transfer systems for each archaeal branch, the chapter is divided into three inclusive sections covering the halophilic and methanogenic Euryarchaeota and the hyperthermophilic Crenarchaeota. Despite varying degrees of difficulty growing Archaea, all three systems are routinely used by laboratories conducting research on archaeal genetics and can be mastered by anyone with a fundamental knowledge of microbial genetic techniques. Under low oxygen tension, Halobacterium sp. NRC-1 induces purple membrane patches in the cell membrane and buoyant gas vesicles intracellularly, which increases the availability of light
Phytogeographers have long recognised the Sino-Japanese Floristic Region (SJFR) of East Asia as the worlds major centre of temperate plant diversity and endemism [1]. Much of the potential primary vegetation of this vast region is composed of warm-temperate deciduous (WTD) forest, as presently found scattered in mid-elevation subtropical (Central/South/East) China, predominant in low-elevation North China and the Korean Peninsula, and disjunctively distributed in the main islands of Japan [1, 2]. Fossil pollen analyses have previously indicated that during the Last Glacial Maximum [LGM: c. 21,000-18,000 yr before present (BP)], the habitat of East Asian WTD forests in the northern parts of their range (e.g., in North China and North Japan) contracted, mainly in response to increased aridification [3, 4]. However, palaeo-biome reconstructions suggest that these forests also expanded across the large expanses of continental shelf (c. 1 million km2) that emerged in the East China Sea (ECS) as a ...
A green-red quasi-analytical algorithm, QAA-GRI, was calibrated to derive inherent optical properties (IOPs) using an in situ dataset from Lake Qiandaohu (QDH). First, 510 nm was chosen as the reference band based on the general structure of the quasi-analytical algorithm (QAA). Second, a green-red index (GRI), which was calculated from the remote sensing reflectance at the three wavelengths (510, 560 and 620 nm), was used to retrieve the total absorption coefficients at the reference band, a(510) . A semi-analytical model based on a(510) and the GRI was proposed to replace the empirical model in original QAA. Subsequently, QAA-GRI, is calibrated to analytically retrieve total absorption coefficient for Lake Qiandaohu (QDH). The algorithm was further validated using the in situ data set collected in East China Sea (ECS) on January 1-12, 2016 and May 25-June 2, 2017. The QAA-GRIs performance in ECS was compared with that of QAA-v5. Our results show that the QAA-GRI performs better in ECS with ...
Archéobactéries 0 questions One of the three domains of life (the others being BACTERIA and Eukarya), formerly called Archaebacteria under the taxon Bacteria, but now considered separate and distinct. They are characterized by: (1) the presence of characteristic tRNAs and ribosomal RNAs; (2) the absence of peptidoglycan cell walls; (3) the presence of ether-linked lipids built from branched-chain subunits; and (4) their occurrence in unusual habitats. While archaea resemble bacteria in morphology and genomic organization, they resemble eukarya in their method of genomic replication. The domain contains at least four kingdoms: CRENARCHAEOTA; EURYARCHAEOTA; NANOARCHAEOTA; and KORARCHAEOTA. ...
Mange arkæer er ekstremofile og lever i ekstreme miljøer, herunder ved temperaturer, der overstiger kogende vands, fx i gejsere, meget saltet vand samt surt eller alkalisk vand. Arkæerne lever fx ved hydrotermiske væld[4] og får fx energi ved at oxidere vældets sorte røg og er dermed kemoautotrof. De lever også ved varme kilder - fx Yellowstone National Parks varme kilder, hvor de først blev opdaget - og vulkanske sprækker.[5] Man har også fundet DNA-rester, som peger på, at der lever arkæer ved Atacama-vulkaner, hvilket er et miljø, der er tæt på det, man finder på Mars.[6] Andre er fundet i en isoleret sø 800 m under iskappen på Antarktis.[7] Arkæerne har en stor diversitet i både morfologi og fysiologi. Noget forskning tyder på, at Euryarchaeota er tættere på eukaryote end på Crenarchaeota. Er dette tilfældet, vil riget Archaea blive opgivet. Mikrobiologer, som anser bakterier for at være parafyletiske, argumenterer også med, at arkæer ikke er tilstrækkeligt ...

The deep sea is an ambiguous term.If you are talking about demersal habitats, the edge of the continental shelf is usually taken as the upper boudary(=~ 200m) with the Bathyal Zone extending down to 2000m. The Bathyal can be further divided into upper(,1000m) and lower( , 1000m).Below 2000m, you have the Abyssal, which again has been arbitrarily divided into upper(2-3000m)and lower(,3000m).Habitats in the deep-sea trenches are in the Hadal Zone. In the Pelagic Realm,using the 200m isobath as the usual dividing point between coastal and oceanic water masses, you have the Epipelagic Zone which corresponds to the euphotic zone(the area of active photosynthesis) whch extends from the surface to 50-200m depending on productivity and water clarity. Then the Mesopelagic from the bottom of the Epipelagic to 1000m, the the Bathypelagic from 1000m to within tens of meters of the bottom wherein the Benthopelagic Zone is located.
