First report of mitochondrial COI in foraminifera and implications for DNA barcoding
Foraminifera are a species-rich phylum of rhizarian protists that are highly abundant in many marine environments and play a major role in global carbon cycling.

Comparison of tRNA and rRNA Phylogenies in Proteobacteria: Implications for the Frequency of Horizontal Gene Transfer [PDF]
The current picture of bacterial evolution is based largely on studies of 16S rRNA. However, this is just one gene. It is known that horizontal gene transfer can occur between bacterial species, although the frequency and implications of this are not fully understood.

Background Reference genes are commonly used as the endogenous normalisation measure for the relative quantification of target genes. The appropriate application of quantitative real-time PCR (RT-qPCR), however, requires the use of reference genes whose ...

Cosmic Thermobiology: Thermal Constraints on the Origin and Evolution of Life in the Universe [PDF]
We review the thermal history of the Universe. We obtain a new estimate for the thermal history of the Earth over the past four billion years using a biological thermometer based on (1) a rough estimate of the absolute time calibration of the genetic distances in the 16S rRNA-based tree of terrestrial life and (2) the maximum growth temperatures of the

Reduction of Alzheimer's disease beta-amyloid pathology in the absence of gut microbiota [PDF]
Alzheimer's disease is the most common form of dementia in the western world, however there is no cure available for this devastating neurodegenerative disorder. Despite clinical and experimental evidence implicating the intestinal microbiota in a number of brain disorders, its impact on Alzheimer's disease is not known.

While total RNA concentrations putatively represent ribosome content, there is a need to homologize various quantification approaches. Thus, total RNA concentrations ([RNA]) provided through UV–Vis spectroscopy (UV), fluorometry‐only (Fluor), and ...

The nucleotides involved in RNA-RNA interaction can be tagged by chemical- or UV-induced crosslinking, and further identified by classical or modern high throughput techniques.

Towards a Taxonomical Consensus: Diversity and Richness Inference from Large Scale rRNA gene Analysis [PDF]
Population analysis is persistently challenging but important, leading to the determination of diversity and function prediction of microbial community members. Here we detail our bioinformatics methods for analyzing population distribution and diversity in large microbial communities.

Reference genes, stably expressing in different tissues and cells, are commonly used as the references in expression analysis. Selecting the optimum reference gene is crucial to the success of experiments.
