PaiI links anaerobic small-RNA regulation to denitrification in Pseudomonas aeruginosa
This paper identifies the small RNA PaiI as an anaerobically induced regulator in Pseudomonas aeruginosa PA14 and shows that it is needed for efficient denitrification under nitrate-respiring conditions.
Co-transcriptional folding and metastable states in riboswitch function
This paper uses NMR spectroscopy to resolve transcription intermediates of the 2'dG riboswitch at single-nucleotide resolution, showing how transcript length and metastable states govern ligand-controlled switching.
CrcZ cross-regulates anoxic biofilm formation in Pseudomonas aeruginosa
This paper shows that the Hfq-binding RNA CrcZ is highly abundant in anoxic Pseudomonas aeruginosa biofilms and that competition for Hfq by CrcZ limits anaerobic biofilm formation.
The MazF regulon and post-transcriptional stress adaptation in Escherichia coli
This paper uses Poly-seq to define the MazF regulon in Escherichia coli, showing how MazF reshapes both mRNA processing and ribosome specificity to reprogram translation during harsh stress.
RNA-seq profiling of Pseudomonas aeruginosa under anoxic cystic fibrosis-like growth
This study uses RNA-seq to compare planktonic, short-term anoxic, and long-term anoxic biofilm states of Pseudomonas aeruginosa PA14 in synthetic cystic fibrosis sputum medium, revealing transcriptomic changes linked...
