Recovery and phylogenetic analysis of novel archaeal rRNA sequences from a deep-sea deposit feeder.

چکیده
In 1992, two independent reports based on small-subunit rRNA gene (SSU rDNA) cloning revealed the presence of novel Archaea among marine bacterioplankton. Here, we report the presence of further novel Archaea SSU rDNA sequences recovered from the midgut contents of a deep-sea marine holothurian. Phylogenetic analyses show that these abyssal Archaea are a paraphyletic component of a highly divergent clade that also includes some planktonic sequences. Our data confirm that this clade is a deep-branching lineage in the tree of life.

Population structure and phylogenetic characterization of marine benthic Archaea in deep-sea sediments.
During the past few years Archaea have been recognized as a widespread and significant component of marine picoplankton assemblages and, more recently, the presence of novel archaeal phylogenetic lineages has been reported in coastal marine benthic environments. We investigated the relative abundance, vertical distribution, phylogenetic composition, and spatial variability of Archaea in deep-se...
متن کاملGenetic diversity of archaea in deep-sea hydrothermal vent environments.
Molecular phylogenetic analysis of naturally occurring archaeal communities in deep-sea hydrothermal vent environments was carried out by PCR-mediated small subunit rRNA gene (SSU rDNA) sequencing. As determined through partial sequencing of rDNA clones amplified with archaea-specific primers, the archaeal populations in deep-sea hydrothermal vent environments showed a great genetic diversity, ...
متن کاملArchaeal diversity associated with in situ samplers deployed on hydrothermal vents on the East Pacific Rise ( 13 ∞ N )
To evaluate possible compositional changes in archaeal communities at a deep-sea hydrothermal vent field scale, we examined five different samples obtained after deploying in situ collectors for different times on three spatially separated venting sulphide structures on the East Pacific Rise (13 ∞ N). Direct cell counts and whole-cell hybridizations with fluorescently labelled 16S rRNA-based ol...
متن کاملMolecular Detection of Novel Genetic Variants Associated to Anaplasma ovis among Dromedary Camels in Iran
To the best of our knowledge, little information is available regarding the presence of Anaplasma species in camels in Iran. This study sought to investigate the presence of Anaplasma species by microscopy and polymerase chain reaction (PCR) assays in 100 healthy dromedaries (Camelus dromedarius) arriving for slaughter. The microscopic examination of Giemsa-stained blood films revealed that Ana...
متن کاملUncultured Archaea in a hydrothermal microbial assemblage: phylogenetic diversity and characterization of a genome fragment from a euryarchaeote.
The polychaete Alvinella pompejana lives in organic tubes on the walls of active hydrothermal chimneys along the East Pacific Rise. To examine the diversity of the archaeal community associated with the polychaete tubes, we constructed libraries by direct PCR amplification and cloning of 16S rRNA genes. Almost half of the sequences of the 16S rRNA gene libraries clustered with uncultured archae...
