The RNA polymerase gene specificity factor sigma 54 is required for homogeneous non-planktonic growth of uropathogenic Escherichia coli

This study identifies sigma 54 as essential for homogeneous non-planktonic growth in uropathogenic E. coli, revealing a non-canonical function beyond its canonical role in transcription initiation.

The adaptive response to long term nitrogen starvation in Escherichia coli requires the breakdown of allantoin

This study investigates how Escherichia coli adapts to long-term nitrogen starvation by revealing the necessity of allantoin degradation for optimal growth recovery.

The assembly of Hfq into foci-like structures in response to long-term nitrogen starvation in Escherichia coli

This study shows Hfq forms reversible foci in E. coli during long-term nitrogen starvation, independent of gene expression and NtrC, aiding adaptation to nutrient stress.

A role for a conserved kinase in the transcriptional control of methionine biosynthesis in Escherichia coli experiencing sustained nitrogen starvation

This study identifies YeaG as a kinase that regulates methionine biosynthesis in E. coli under sustained nitrogen starvation by modulating the activity of the transcriptional repressor MetJ.

Phenotypic consequences of RNA polymerase dysregulation in Escherichia coli

This study shows that perturbing RNA polymerase activity in E. coli leads to biphasic growth and increased tolerance to antibacterial stresses.
