Quartet Analysis of Putative Horizontal Gene Transfer in Crenarchaeota
Journal of Molecular Evolution, 2013Horizontal gene transfers (HGT) between four Crenarchaeota species (Metallosphaera cuprina Ar-4T, Acidianus hospitalis W1T, Vulcanisaeta moutnovskia 768-28T, and Pyrobaculum islandicum DSM 4184T) were investigated with quartet analysis. Strong support was found for individual genes that disagree with the phylogeny of the majority, implying genomic ...

Crenarchaeota colonize terrestrial plant roots
Environmental Microbiology, 2000Microorganisms that colonize plant roots are recruited from, and in turn contribute substantially to, the vast and virtually uncharacterized phylogenetic diversity of soil microbiota. The diverse, but poorly understood, microorganisms that colonize plant roots mediate mineral transformations and nutrient cycles that are central to biosphere functioning.

Autotrophic CO2 fixation pathways in archaea (Crenarchaeota)
Archives of Microbiology, 2003Representative autotrophic and thermophilic archaeal species of different families of Crenarchaeota were examined for key enzymes of the known autotrophic CO(2) fixation pathways. Pyrobaculum islandicum ( Thermoproteaceae) contained key enzymes of the reductive citric acid cycle.

Structural and thermodynamic insights into the Cren7 mediated DNA organization in Crenarchaeota
Physical Chemistry Chemical Physics, 2022Cren7 induced bending and compaction of DNA involve a cumulative outcome of electrostatic and non-electrostatic interactions with the latter majorly contributing to its stabilization.

Microbes and Environments, 2010 A transect from the Tomoe River Mouth through Shimizu Port to Suruga Bay, Japan, was examined between 2005 and 2009 to reveal the population dynamics of Crenarchaeota and Euryarchaeota in an estuary environment. Crenarchaeota tended to increase in abundance in waters deeper than 100 m compared with Euryarchaeota, and comprised 11% of total direct ...

High abundance of Crenarchaeota in a temperate acidic forest soil.
FEMS microbiology ecology, 2007The objective of the study was to elucidate the depth distribution and community composition of Archaea in a temperate acidic forest soil. Numbers of Archaea and Bacteria were measured in the upper 18 cm of the soil, and soil cores were sampled on two separate occasions using quantitative PCR targeting 16S rRNA genes.

Biogeography and Landscape-Scale Diversity of the Dominant Crenarchaeota of Soil
Microbial Ecology, 2006We surveyed the diversity of soil Archaea across a large scale elevational gradient of ecosystem types, from foothills forest to alpine tundra in the Front Range of the Rocky Mountains. We used a dilution technique to sequence the single most abundant archaeal 16S rDNA sequence in each of the 40 soil cores distributed across the gradient to compare our

The Biological Bulletin, 1999
Analysis of small subunit rRNAs retrieved from mixed microbial populations has provided a framework for understanding global microbial diversity (1). These molecular phylogenetic analyses have revealed the presence of previously undetected species and lineages in a wide variety of microbial habitats, and placed newly discovered microbial groups on a ...

Ammonia-oxidising Crenarchaeota: important players in the nitrogen cycle?
Trends in Microbiology, 2006Cultivation-independent molecular surveys show that members of the kingdom Crenarchaeota within the domain Archaea represent a substantial component of microbial communities in aquatic and terrestrial environments. Recently, metagenomic studies have revealed that such Crenarchaeota contain and express genes related to those of bacterial ammonia ...

Phylum Al. Crenarchaeota phy. nov.
2001The phylum consists of a single class, the Thermoprotei, which is well supported by 16S rDNA sequence data. It is subdivided into three orders: the Thermoproteales, the Desulfurococcales, and the Sulfolobales. Morphologically diverse, including rods, cocci, filamentous forms, and disk-shaped cells. Stain Gram-negative. Motility observed in some genera.
