Epitranscriptomic control of stress adaptations in Escherichia coli

This study maps epitranscriptomic changes in E. coli under oxidative and acid stress, identifying RNA modifications that influence stress adaptation and survival.

Detection of stress-dependent m5C rRNA dynamics in Escherichia coli using m5C-Rol-LAMP

The paper introduces m5C-Rol-LAMP to detect m5C in RNA, showing stress-dependent changes in E. coli rRNA modifications.

Sequestration of the phagocyte metabolite itaconate by P. aeruginosa RpoN promotes successful pulmonary infection

This study shows that P. aeruginosa sequesters itaconate by binding it to RpoN, enhancing its metabolic adaptation and promoting pulmonary infection.

Direct RNA sequencing of the Escherichia coli epitranscriptome uncovers alterations under heat stress

This study uses direct RNA sequencing to analyze RNA modifications in E. coli under heat stress, revealing changes in m5C, m6A, and m6,6A levels in rRNA and shifts in mRNA modification patterns.

Depletion of m6A-RNA in Escherichia coli reduces the infectious potential of T5 bacteriophage

This study shows that reducing m6A RNA levels in E. coli decreases T5 phage infection efficiency but not other phages.
