Complete chloroplast genome of Triticum aestivum cultivar ‘Keumkang’ from Korea (Poaceae) and comparative chloroplast genomes of the members of the Triticum genus

open access: yesJournal of the Science of Food and Agriculture, Volume 106, Issue 6, Page 3732-3744, April 2026.
Abstract BACKGROUND Bread wheat (Triticum aestivum L.) is a major global food crop, and understanding its maternal lineage and genetic diversity is essential for breeding, authentication, and evolutionary studies. Chloroplast genomes provide valuable markers for phylogenetic inference and cultivar discrimination; however, conventional plant DNA ...

Multidrug-resistant Mycobacterium tuberculosis, Bangui, Central African Republic [PDF]

open access: yes, 2006
We investigated multidrug-resistant (MDR) Mycobacterium tuberculosis strains in Bangui, Central African Republic. We found 39.6% with the same spoligotype and synonymous single nucleotide polymorphism in the mutT1 gene.

Acetyl‐Phosphate Dependent Protein Acetylation in Neisseria gonorrhoeae

open access: yesMicrobiologyOpen, Volume 15, Issue 2, April 2026.
The role of acetyl‐phosphate‐dependent non‐enzymatic protein acetylation in Neisseria gonorrhoeae was investigated through the deletion of the phosphotransacetylase (pta) and the acetate kinase (ackA) genes, this led to a decrease and increase in protein acetylation, respectively.

Rifampin and rpoB mutations can alter DNA supercoiling in Escherichia coli [PDF]

open access: yesJournal of Bacteriology, 1988
Two cases are described which indicate that RNA polymerase could alter DNA supercoiling. One occurred in a topA mutant in which abnormally high levels of plasmid supercoiling were lowered by rifampin, an inhibitor of the beta subunit of RNA polymerase. The second case involves suppression of a temperature-sensitive gyrB mutation by a rifampin-resistant

Antimicrobial Effect of Spices and Their Phytochemicals: A Novel Approach to Overcoming Antibiotic Resistance

open access: yesMedComm, Volume 7, Issue 4, April 2026.
This graphical abstract shows the antibacterial potential of phytochemicals from 15 spices, showcasing key compounds, their extraction methods, and mechanisms of action. It highlights membrane disruption, ROS generation, enzyme inhibition, and biofilm prevention as core antibacterial pathways.

rpoB Gene Sequencing for Identification of Rapidly Growing Mycobacteria

open access: yesArchives of Pediatric Infectious Diseases, 2016
Background: Rapidly growing mycobacteria (RGM) are increasingly recognized as a cause of human infections. Rapid and reliable identification of RGM at species level should be carried out as a means of effective patient managements. Methods: Twenty clinical samples of RGM isolated from suspected tuberculosis (TB) patients were included.

Genetic diversity of Legionella pneumophila inferred from rpoB and dotA sequences [PDF]

open access: yesClinical Microbiology and Infection, 2006
This study characterised the population structure of Legionella pneumophila by comparing the rpoB (300-bp) and dotA (360-bp) sequences of 267 isolates (18 reference strains, 149 Korean isolates and 100 Japanese isolates). In addition to the six clonal subgroups established previously, four subgroups, P-V to P-VIII, were identified.
