Microvariation Artifacts Introduced by PCR and Cloning of Closely Related 16S rRNA Gene Sequences [PDF]
A defined template mixture of seven closely related 16S-rDNA clones was used in a PCR-cloning experiment to assess and track sources of artifactual sequence variation in 16S rDNA clone libraries. At least 14% of the recovered clones contained aberrations.

A genomic approach to the study of Tribolium castaneum genetics, development & evolution [PDF]
During the last decade, Tribolium castaneum has become the insect of choice for comparative genetics and developmental studies outside of drosophilids. Until recently, most molecular studies have focused on the comparative analysis of early development ...

Mycosphaerella podagrariae - a necrotrophic phytopathogen forming a special cellular interaction with its host Aegopodium podagraria [PDF]
We present a new kind of cellular interaction found between Mycosphaerella podagrariae and Aegopodium podagraria, which is remarkably different to the interaction type of the obligate biotrophic fungus Cymadothea trifolii, another member of the ...

Molecular characterization and biodiversity of wood-decaying fungi in French Guiana [PDF]
Fungi from tropical regions are currently under-represented in the classification system. Indeed, difficult access to tropical forests and irregular occurrence carpophores make it complicated to study fungus species in such environments, unlike in ...

Multiple prebiotic metals mediate translation. [PDF]
Today, Mg2+ is an essential cofactor with diverse structural and functional roles in life's oldest macromolecular machine, the translation system. We tested whether ancient Earth conditions (low O2, high Fe2+, and high Mn2+) can revert the ribosome to a ...

cis-acting sequences and trans-acting factors in the localization of mRNA for mitochondrial ribosomal proteins [PDF]
mRNA localization is a conserved post-transcriptional process crucial for a variety of systems. Although several mechanisms have been identified, emerging evidence suggests that most transcripts reach the protein functional site by moving along ...

Relating the metatranscriptome and metagenome of the human gut [PDF]
Although the composition of the human microbiome is now wellstudied, the microbiota’s \u3e8 million genes and their regulation remain largely uncharacterized.

Role of the Mitochondrial Genome During Early Development in Mice [PDF]
The role of the mitochondrial genome in early development and differentiation was studied in mouse embryos cultured in vitro from the two to four cell stage to the blastocyst (about 100 cells).

Background Ribosomal RNA (rRNA) consists of four non‐coding RNAs, the 28S, 5.8S, 18S, and 5S rRNA. Abnormal expression of rRNA has been found in multiple tumors, and the methylation of rDNA promoter may affect rRNA expression as an epigenetic regulatory ...
