Nested PCR to optimize rpoB metabarcoding for low-concentration and host-associated bacterial DNA [PDF]
Housekeeping genes have proven to be effective taxonomic markers for characterizing bacterial microbiota in short-read amplicon metabarcoding studies. A region of the rpoB gene has been shown to minimize Operational Taxonomic Unit (OTU) overestimation ...

Background: Rifampicin (RIF) resistance in Mycobacterium tuberculosis is frequently caused by mutations in the rpoB gene. These mutations are associated with a fitness cost, which can be overcome by compensatory mutations in other genes, among which rpoC

Rifampicin resistance conferring mutations among Mycobacterium tuberculosis strains in Rwanda
Background: The World Health Organization-endorsed phenotypic and genotypic drug-susceptibility testing (gDST/pDST) assays for the detection of rifampicin-resistant (RR) tuberculosis (TB), may miss some clinically relevant rpoB mutants, including ...

Haloglomus irregulare gen. nov., sp. nov., a New Halophilic Archaeon Isolated from a Marine Saltern [PDF]
A halophilic archaeal strain, designated F16-60T, was isolated from Isla Cristina marine saltern in Huelva, Spain. Cells were pleomorphic, irregular, non-motile, and Gram-stain-negative. It produced red-pigmented colonies on agar plates.

Genotypic and phenotypic characteristics of Cronobacter species, with particular attention to the newly reclassified species C. helveticus, C. pulveris, and C. zurichensis [forthcoming] [PDF]
In 2013, Enterobacter helveticus, E. pulveris and E. turicensis, were reclassified as Cronobacter helveticus, C. pulveris and C. zurichensis, respectively. Previously these species had been used as negative controls for some Cronobacter detection assays.

Phytochrome activates the plastid-encoded RNA polymerase for chloroplast biogenesis via nucleus-to-plastid signaling. [PDF]
Light initiates chloroplast biogenesis by activating photosynthesis-associated genes encoded by not only the nuclear but also the plastidial genome, but how photoreceptors control plastidial gene expression remains enigmatic.
