Circularization of 23S rRNA but not 16S rRNA within archaeal ribosomes [PDF]

open access: yesGenome Biology
Background Processing of archaeal 16S and 23S rRNAs is believed to involve excision of individual rRNAs from polycistronic precursors, circularization of excised rRNAs, and re-linearization before the incorporation into ribosomes.

A comparison of 16S rRNA-gene and 16S rRNA-transcript derived microbial communities in bulk and rhizosphere soils [PDF]

open access: yesFrontiers in Microbiology
Root exudates in a plant’s rhizosphere alters microbial community membership and activity, which can in turn alter a plant’s health and fitness. In this study we characterized bacterial community composition, using 16S rRNA-gene (DNA) sequencing to ...

Simultaneous measurement of 16S-rRNA and pre-16S-rRNA as a strategy to monitor clinical tuberculosis [PDF]

open access: yesFrontiers in Antibiotics
BackgroundCulture-based biomarkers of TB treatment response monitoring, e.g., Mycobacterial Growth Indicatory Tube (MGIT), are compromised when bacteria enter a non-replicating persister phase limiting the measurement of antibiotic efficacy and ...

Utility of 16S rRNA PCR performed on clinical specimens in patient management

open access: yesInternational Journal of Infectious Diseases, 2017
Background: Broad-range 16S rRNA PCR can be used for the detection and identification of bacteria from clinical specimens in patients for whom there is a high suspicion of infection and cultures are negative.

Long-read MinION™ sequencing of 16S and 16S-ITS-23S rRNA genes provides species-level resolution of Lactobacillaceae in mixed communities

open access: yesFrontiers in Microbiology, 2023
The Lactobacillaceae are lactic acid bacteria harnessed to deliver important outcomes across numerous industries, and their unambiguous, species-level identification from mixed community environments is an important endeavor.

PCR biases distort bacterial and archaeal community structure in pyrosequencing datasets [PDF]

open access: yes, 2012
As 16S rRNA gene targeted massively parallel sequencing has become a common tool for microbial diversity investigations, numerous advances have been made to minimize the influence of sequencing and chimeric PCR artifacts through rigorous quality control ...

Phylogenetic Clustering of Soil Microbial Communities by 16S rRNA but Not 16S rRNA Genes [PDF]

open access: yesApplied and Environmental Microbiology, 2012
ABSTRACT We evaluated phylogenetic clustering of bacterial and archaeal communities from redox-dynamic subtropical forest soils that were defined by 16S rRNA and rRNA gene sequences. We observed significant clustering for the RNA-based communities but not the DNA-based communities, as well as increasing clustering over time of the highly ...

Variable Region Sequences Influence 16S rRNA Performance

open access: yesMicrobiology Spectrum, 2023
16S rRNA gene sequences are commonly analyzed for taxonomic and phylogenetic studies because they contain variable regions that can help distinguish different genera. However, intra-genus distinction using variable region homology is often impossible due

OTU analysis using metagenomic shotgun sequencing data. [PDF]

open access: yesPLoS ONE, 2012
Because of technological limitations, the primer and amplification biases in targeted sequencing of 16S rRNA genes have veiled the true microbial diversity underlying environmental samples. However, the protocol of metagenomic shotgun sequencing provides
