On the reducibility of “16 + 16” supergravity

Physics Letters B, 1986
Abstract It is shown, in the framework of N = 1, d = 4 superconformal tensor calculus, that the recently proposed supergravity theory based on a 16 + 16 multiplet is reducible and equivalent to either a real linear multiplet coupled to old minimal supergravity or to a chiral multiplet coupled to new minimal supergravity.

The gyrB gene is a useful phylogenetic marker for exploring the diversity of flavobacterium strains isolated from terrestrial and aquatic habitats in Antarctica [PDF]

, 2011
Within the phylum Bacteroidetes, the gyrB gene, encoding for the B subunit of the DNA gyrase, has been used as phylogenetic marker for several genera closely related to Flavobacterium.

Evaluation of general 16S ribosomal RNA gene PCR primers for classical and next-generation sequencing-based diversity studies

Nucleic Acids Research, 2012
16S ribosomal RNA gene (rDNA) amplicon analysis remains the standard approach for the cultivation-independent investigation of microbial diversity. The accuracy of these analyses depends strongly on the choice of primers.

Jumping the green wall: The use of PNA‐DNA clamps to enhance microbiome sampling depth in wildlife microbiome research

Ecology and Evolution, 2020
As microbiome research moves away from model organisms to wildlife, new challenges for microbiome high‐throughput sequencing arise caused by the variety of wildlife diets.

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

Frontiers 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.

Utilization of Pyrosequencing to Monitor the Microbiome Dynamics of Probiotic Treated Poultry (Gallus gallus domesticus) during Downstream Poultry Processing [PDF]

, 2017
Antibiotic growth promoters that have been historically employed to control pathogens and increase the rate of animal development for human consumption are currently banned in many countries.

Phylogenies of the 16S rRNA gene and its hypervariable regions lack concordance with core genome phylogenies

Microbiome, 2022
Background The 16S rRNA gene is used extensively in bacterial phylogenetics, in species delineation, and now widely in microbiome studies. However, the gene suffers from intragenomic heterogeneity, and reports of recombination and an unreliable ...
