First report of mitochondrial COI in foraminifera and implications for DNA barcoding

open access: yesScientific Reports, 2021
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]

open access: yesarXiv, 2004
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.

Validation of reference genes as internal control for studying viral infections in cereals by quantitative real-time RT-PCR

open access: yesBMC Plant Biology, 2010
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]

open access: yesarXiv, 2003
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]

open access: yesarXiv, 2015
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.

Skeletal muscle ribosome analysis: A comparison of common assay methods and utilization of a novel RiboAb antibody cocktail

open access: yesPhysiological Reports
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 ...

Mapping mRNA-18S rRNA Contacts Within Translation Initation Complex by Means of Reverse Transcriptase Termination Sites and RNAseq

open access: yesBio-Protocol, 2020
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]

open access: yesarXiv, 2010
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 for quantitative real-time PCR analysis and quantitative expression of P5CS in Agropyron mongolicum under drought stress

open access: yesJournal of Integrative Agriculture, 2016
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.
