Taxonomy of the canine Mollicutes by 16S rRNA gene and 16S/23S rRNA intergenic spacer region sequence comparison [PDF]

International Journal of Systematic and Evolutionary Microbiology, 2004
The taxonomy of canine Mollicutes is described, based on phylogenetic analysis of 16S rRNA gene and 16S/23S rRNA intergenic spacer (IGS) region sequences. The nucleotide sequences of the 16S rRNA gene of two untyped mycoplasmas and the IGS region of 11 Mycoplasma species were determined and used for phylogenetic analysis.

Small RNA pathways in mammalian oocytes

FEBS Open Bio, EarlyView.
Three distinct small RNA pathways operate in mammalian oocytes: RNAi interference (RNAi), the microRNA (miRNA) pathway, and the PIWI‐associated RNA (piRNA) pathway. These pathways use small RNAs to guide sequence‐specific repression and contribute to oocyte biology by targeting genes and mobile elements or appear insignificant since different ...

Intrageneric structure of the genus Gluconobacter analyzed by the 16S rRNA gene and 16S-23S rRNA gene internal transcribed spacer sequences

The Journal of General and Applied Microbiology, 2006
Forty-nine strains belonging to the genus Gluconobacter were re-examined with respect to their species identification based on the sequences of the 16S rDNA and 16S-23S rDNA internal transcribed spacer regions (ITS). A phylogenetic tree constructed from the 16S rDNA sequences indicated the presence of five clusters corresponding, respectively, to the ...

Activity profiles for marine sponge-associated bacteria obtained by 16S rRNA vs 16S rRNA gene comparisons [PDF]

The ISME Journal, 2010
Abstract The phylogenetic diversity of microorganisms in marine sponges is becoming increasingly well described, yet relatively little is known about the activities of these symbionts. Given the seemingly favourable environment provided to microbes by their sponge hosts, as indicated by the extraordinarily high abundance of sponge ...

Hyperosmotic stress‐induced redistribution of pre‐mRNA cleavage factor I subunits is associated with shifts in alternative polyadenylation

FEBS Open Bio, EarlyView.
Hyperosmotic stress triggers the relocation of the CFIm complex from the nucleus to the cytoplasm. This shift creates a nuclear ‘stoichiometric bottleneck’, limiting CFIm availability for mRNA processing. Consequently, specific mRNAs like NUDT21 and DICER1 undergo targeted 3′UTR shortening, demonstrating how spatial protein dynamics drive rapid ...

Harnessing the intragenomic variability of rRNA operons to improve differentiation of Vibrio species

Scientific Reports
Although the 16S rRNA gene is frequently used as a phylogenetic marker in analysis of environmental DNA, this marker often fails to distinguish closely related species, including those in the genus Vibrio.

In Vitro Analysis of the Pea Chloroplast 16S rRNA Gene Promoter [PDF]

Molecular and Cellular Biology, 1989
A cloned pea chloroplast 16S rRNA gene promoter has been characterized in detail by use of a homologous in vitro transcription system that contains a highly purified chloroplast RNA polymerase. The in vivo and in vitro 16S rRNA transcriptional start site has been identified to be a T on the plus strand, 158 bases upstream of the mature 5' end of the ...

From energy provision to protein synthesis: Tunnelling nanotubes as mediators of intercellular metabolic cooperation in cancer

FEBS Open Bio, EarlyView.
The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.

Evaluating the effect of γ‐oryzanol on MASLD pathology using a medaka fish model

FEBS Open Bio, EarlyView.
This study explores a liver disease called MASLD, which is increasing worldwide and can lead to serious damage. Researchers used medaka fish instead of rodents to test a food compound, γ‐oryzanol. Fish fed this compound had less liver fat and healthier gut bacteria.

Do we need a standardized 16S rRNA gene amplicon sequencing analysis protocol for poultry microbiota research?

Poultry Science
Bacteria are the major component of poultry gastrointestinal tract (GIT) microbiota and play an important role in host health, nutrition, physiology regulation, intestinal development, and growth.
