This study identifies AstR as a regulator of ornithine catabolism in Acinetobacter baumannii, essential for gut colonization by enabling competition with the microbiota.

The paper identifies DimA, a microprotein that activates photo-sensing in Pseudomonas aeruginosa by triggering proteolysis of MucA and enhancing algB expression through a positive feedback loop.

This study shows that A. baumannii uses ornithine to compete with gut microbiota and persist in mice, with dietary ornithine promoting its carriage.

This study identifies DcaP-family porins as essential for carboxylic acid utilization and infection in A. baumannii, showing functional redundancy and validating their potential as therapeutic targets.

The paper develops Swarm-seq to assess CsrA homologs' ability to regulate swarming motility, revealing functional divergence in RNA-binding specificity across bacterial species.

This study identifies TES-1 as a protein that stabilizes junctional actin networks during cell shape changes in C. elegans embryos by preventing self-injury under tension.
