Deletion of the ribosomal protein gene rpmJ activates zntA transcription through a translation-dependent mechanism in Escherichia coli

The paper shows that deleting rpmJ in E. coli increases zntA transcription via a translation-dependent mechanism involving early zntA mRNA translation.

Overexpression of Escherichia coli yaiX Confers Multidrug Resistance and Enhances Virulence in the Silkworm Infection Model

This study identifies YaiX overexpression in E. coli as a factor conferring multidrug resistance and enhanced virulence in silkworms.

Autoclaving and long-term storage deplete glutamine sources in complex media and affect bacterial phenotypes

This study shows autoclaving and long-term storage reduce glutamine in complex media, affecting bacterial growth and phenotypes.

Knockout of tusA facilitates flagella formation and cationic antimicrobial resistance by disrupting Fur transcriptional regulation in Escherichia coli

This study shows that tusA deletion in E. coli disrupts Fur regulation, leading to increased flagella formation and resistance to cationic antimicrobials.

Xenopus laevis as an infection model for human pathogenic bacteria

This study shows that Xenopus laevis can model sepsis caused by human pathogenic bacteria and can be used to evaluate antimicrobial efficacy and identify virulence genes.

Escherichia coli growth under low pH, low temperature, and high osmotic stress conditions requires the wzxE flippase for the enterobacterial common antigen intermediate

This study shows that the wzxE flippase is essential for E. coli survival under low pH, low temperature, and high osmotic stress by suppressing the negative effects of ECA intermediates.

Overexpression of Ribosomal Proteins Leads to Zn Resistance in Escherichia coli

This study shows that overexpressing 48 out of 54 ribosomal proteins in E. coli confers Zn resistance, dependent on ZntA and Lon protease.

Overexpression of diglucosyldiacylglycerol synthase leads to daptomycin resistance in Bacillus subtilis

This study shows that overexpression of ugtP in Bacillus subtilis increases diglucosyldiacylglycerol levels, altering phospholipid composition and conferring daptomycin resistance without changing cell surface charge.

Hybrid assembly using ultra-long reads resolves repeats and completes the genome sequence of a laboratory strain of Staphylococcus aureus subsp. aureus RN4220

This study uses hybrid long-read and short-read sequencing to complete the genome of Staphylococcus aureus RN4220, resolving repeats and identifying previously fragmented genes.

De novo transcriptome assembly of the African bullfrog Pyxicephalus adspersus for molecular analysis of aestivation

This study presents the first de novo transcriptome assembly of the African bullfrog Pyxicephalus adspersus, identifying novel genes and aestivation-related genes.
