Multiple Ribosomal RNA Operons in Bacteria; Their Concerted Evolution and Potential Consequences on the Rate of Evolution of Their 16S rRNA

Frontiers in Microbiology, 2018
Bacterial species differ greatly in the number and location of the rRNA operons which may be present in the bacterial chromosomes and plasmids. Most bacterial species contain more than one ribosomal RNA operon copy in their genomes, with some species ...

Diagnostic Techniques for Early Detection of Phytoplasma Diseases

Syrian Journal for Science and Innovation, 2023
Phytoplasmas are a type of bacteria, specifically belonging to the group of Mollicutes, characterized by their lack of cell walls and inability to be cultured in lab settings.

The essential nature of YqfG, a YbeY homologue required for 3′ maturation of Bacillus subtilis 16S ribosomal RNA is suppressed by deletion of RNase R

Nucleic Acids Research, 2018
Ribosomal RNAs are processed from primary transcripts containing 16S, 23S and 5S rRNAs in most bacteria. Maturation generally occurs in a two-step process, consisting of a first crude separation of the major species by RNase III during transcription ...

Microbial communities in dark oligotrophic volcanic ice cave ecosystems of Mt. Erebus, Antarctica. [PDF]

, 2015
The Earth's crust hosts a subsurface, dark, and oligotrophic biosphere that is poorly understood in terms of the energy supporting its biomass production and impact on food webs at the Earth's surface.

Globicatella bacteraemia identified by 16S ribosomal RNA gene sequencing [PDF]

Journal of Clinical Pathology, 2006
Background: Globicatella are streptococcus-like organisms that have been rarely isolated from clinical specimens. Their epidemiology and clinical significance remain largely unknown. Aims: To describe two cases of Globicatella bacteraemia identified by 16S ribosomal RNA (rRNA) gene ...

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

FEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.
