Ribosomal small subunit sequence diversity of Scutellospora within single spores and roots of bluebell from a woodland community. [PDF]
, 1999 Roots of bluebell (Hyacinthoides nonscripta) were sampled from a woodland in Yorkshire,UK and spores of an arbuscular mycorrhizal fungus Scutellospora sp., were obtained from the surrounding soil.

DNA replication initiator Cdc6 also regulates ribosomal DNA transcription initiation [PDF]
Journal of Cell Science, 2016 ABSTRACT RNA-polymerase-I-dependent ribosomal DNA (rDNA) transcription is fundamental to rRNA processing, ribosome assembly and protein synthesis. However, how this process is initiated during the cell cycle is not fully understood.

Phylogenetic and phyletic studies of informational genes in genomes highlight existence of a 4 domain of life including giant viruses. [PDF]
PLoS ONE, 2010 The discovery of Mimivirus, with its very large genome content, made it possible to identify genes common to the three domains of life (Eukarya, Bacteria and Archaea) and to generate controversial phylogenomic trees congruent with that of ribosomal genes,

Alterations of the mitochondrial proteome caused by the absence of mitochondrial DNA: A proteomic view [PDF]
, 2006 The proper functioning of mitochondria requires that both the mitochondrial and the nuclear genome are functional. To investigate the importance of the mitochondrial genome, which encodes only 13 subunits of the respiratory complexes, the mitochondrial ...

CX-5461 Preferentially Induces Top2α-Dependent DNA Breaks at Ribosomal DNA Loci
BiomedicinesWhile genotoxic chemotherapeutic agents are among the most effective tools to combat cancer, they are often associated with severe adverse effects caused by indiscriminate DNA damage in non-tumor tissue as well as increased risk of secondary ...

Morphological and molecular identification of filamentous fungi isolated from cosmetic powders
Brazilian Archives of Biology and Technology, 2012 Seven fungi were isolated from 50 samples of cosmetic powders. Morphological analyses and ribosomal DNA Internal Transcribed Spacers sequencing were performed which allowed the discrimination of the isolated fungi as Aspergillus fumigatus, Penicillium sp.

Catalogue of fungi in China 2. Ramaria from northern China
MycologyThe species of Ramaria are coralloid-fungi with intricately branched and vividly coloured basidiomata. There are many studies on the genus Ramaria in China, but molecular phylogenetic analysis is rarely employed.

Discontinuous transcription of ribosomal DNA in human cells.
PLoS ONE, 2020 Numerous studies show that various genes in all kinds of organisms are transcribed discontinuously, i.e. in short bursts or pulses with periods of inactivity between them.

PCR primers for metazoan nuclear 18S and 28S ribosomal DNA sequences. [PDF]
PLoS ONE, 2012 BACKGROUND: Metagenetic analyses, which amplify and sequence target marker DNA regions from environmental samples, are increasingly employed to assess the biodiversity of communities of small organisms. Using this approach, our understanding of microbial

FabR regulates Salmonella biofilm formation via its direct target FabB [PDF]
, 2016 Background: Biofilm formation is an important survival strategy of Salmonella in all environments. By mutant screening, we showed a knock-out mutant of fabR, encoding a repressor of unsaturated fatty acid biosynthesis (UFA), to have impaired biofilm ...
