We assess phylogenetic relationships within the polychaete family Hesionidae from morphological data combined with nucleotide data from 18S rDNA, 28S rDNA, 16S rDNA and COI. Parsimony and Bayesian analyses were performed on two data sets; the first was based on a more restricted set of terminals with both morphological and molecular data (17 ingroup ...

Immunogenicity of rDNA-derived pharmaceuticals
Trends in Pharmacological Sciences, 2002Many biopharmaceuticals have been reported to induce the production of antibodies. Several factors influence immunogenicity, including the methods of production, formulation and storage as well as patient characteristics (e.g. type of disease and genetic background).

rDNA transcription and cardiac hypertrophy
Trends in Cardiovascular Medicine, 1993A common result of the various stimuli that alter the growth rates of cells is a parallel alteration of the rate of ribosome biogenesis. In many cell types, this mandates an altered rate of ribosomal RNA synthesis. Preliminary studies indicate that rDNA transcription may in fact be regulated at more than one level or step.

Ribosomal RNA and rDNA sequence analyses
Gene, 1992The potential of ribosomal (r) RNA and the encoding genes (rDNA) to elucidate natural relationships has been dramatically extended by improved sequencing approaches and the application of polymerase chain reaction. Sequence information on 16S and 23S rRNA/DNA from 69 strains of 53 Streptomyces species allows determination of regions that can be used as

rDNA magnification in D. melanogaster: State of rDNA copies following the first step
Molecular and General Genetics MGG, 1979D. melanogaster males of XYbb/O genetic constitution undergoing rDNA magnification were mated singly to XXbb+/O females, yielding XYbb/O male progeny, and to XNO- w sn bb+ females, yielding XYbb/XNO- females. The male and female offspring were scored for the bb+ phenotype.

SSU rDNA phylogeny of cladoniiform lichens
American Journal of Botany, 1998To examine phylogenetic relationships among the “cladoniiform” lichenized fungi, i.e., the families Cladoniaceae, Baeomycetaceae, Icmadophilaceae, Stereocaulaceae, and Siphulaceae, and to provide evidence for the anticipated independent origins of podetia and pseudopodetia, we conducted phylogenetic analyses of SSU (small subunit) rDNA sequences from ...

16S rDNA methods in soil microbiology
Current Opinion in Biotechnology, 1999With the introduction of molecular methods, the past decade has seen renewed interest in soil microbiology. New and exciting molecular technologies and the promise of finally opening the microbial black box in soil drive much of this interest. Although these pioneering studies have added much to our knowledge of microbial diversity in soils, it is ...

rDNA Transcription during Xenopus laevis Oogenesis
Biochemical and Biophysical Research Communications, 2002It is generally believed that, during Xenopus laevis oogenesis, polymerase I transcription is high in the early vitellogenic oocytes (stages III and IV) and very low in later stages. We used a combination of RNA labeling, nuclease S1 protection assays, Northern blot, and half-life measurement of preribosomal RNA to reinvestigate the pattern of ...

Regulation of rDNA stability by sumoylation
DNA Repair, 2009Repair of DNA lesions by homologous recombination relies on the copying of genetic information from an intact homologous sequence. However, many eukaryotic genomes contain repetitive sequences such as the ribosomal gene locus (rDNA), which poses a risk for illegitimate recombination.
