Time series genome-centric analysis unveils bacterial response to operational disturbance in activated sludge [PDF]

open access: yes, 2019
Understanding ecosystem response to disturbances and identifying the most critical traits for the maintenance of ecosystem functioning are important goals for microbial community ecology.

Regulatory Aspects of rRNA Modification and Pre-rRNA Processing

open access: yes, 2014
The major types of posttranscriptional modification are the isomerization of uracil to pseudouridine, 2′-O-methylation of the ribose moieties and base methylation. In addition to their roles in pre-rRNA modification, both Dim1p and Cbf5p are required for pre-rRNA processing, and Pet56p is required for synthesis of mitochondrial large ribosomal subunits.

The nucleolar origin of rRNA [PDF]

open access: yesThe Journal of Cell Biology, 2005
The nucleolus was identified early on as a site that made a lot of RNA (Caspersson and Schultz, 1940); later that RNA was shown to have metabolic dynamics distinct from those of chromosomally-derived RNA (McMaster-Kaye and Taylor, 1958).

PHYLOGENETIC DIVERSITY OF BACTERIAL POPULATION IN RUMEN

open access: yesActa Agriculturae Slovenica, 1998
In order to investigate the microbial diversity in rumen, bacterial 16S rRNA genes were amplified from total microbial DNA isolated from rumen fluid. The amplificated genes were incorporated into pBluescript SK II vector and electroporated into E.coli ...

Eukaryotic 5S rRNA biogenesis [PDF]

open access: yesWIREs RNA, 2011
AbstractThe ribosome is a large complex containing both protein and RNA which must be assembled in a precise manner to allow proper functioning in the critical role of protein synthesis. 5S rRNA is the smallest of the RNA components of the ribosome, and although it has been studied for decades, we still do not have a clear understanding of its function

Diversity of 23S rRNA genes within individual prokaryotic genomes. [PDF]

open access: yesPLoS ONE, 2009
The concept of ribosomal constraints on rRNA genes is deduced primarily based on the comparison of consensus rRNA sequences between closely related species, but recent advances in whole-genome sequencing allow evaluation of this concept within organisms ...

Isolation and characterization of a thermophilic, obligately anaerobic and heterotrophic marine Chloroflexi bacterium from a Chloroflexi dominated microbial community associated with a Japanese shallow hydrothermal system, and proposal for Thermomarinilinea lacunofontalis gen. nov., sp. nov. [PDF]

open access: yes, 2013
A novel marine thermophilic and heterotrophic Anaerolineae bacterium in the phylum Chloroflexi, strain SW7T, was isolated from an in situ colonization system deployed in the main hydrothermal vent of the Taketomi submarine hot spring field located on the

Strategy for the identification of micro-organisms producing food and feed products : bacteria producing food enzymes as study case [PDF]

open access: yes, 2020
Recent European regulations require safety assessments of food enzymes (FE) before their commercialization. FE are mainly produced by micro-organisms, whose viable strains nor associated DNA can be present in the final products.

Locus-specific ribosomal RNA gene silencing in nucleolar dominance. [PDF]

open access: yesPLoS ONE, 2007
The silencing of one parental set of rRNA genes in a genetic hybrid is an epigenetic phenomenon known as nucleolar dominance. We showed previously that silencing is restricted to the nucleolus organizer regions (NORs), the loci where rRNA genes are ...
