This study uses experimental evolution to test the necessity of chemotaxis pathway components in E. coli, finding that core components are essential but some auxiliary proteins can be compensated for.

This study investigates how AI-2 signaling and chemotaxis in E. coli influence its competitive interaction with Salmonella Typhimurium in the gut, affecting colonization resistance and metabolism.

The paper shows Hfq regulates RecB protein levels in E. coli by reducing translation of recB mRNA, maintaining optimal RecB abundance.
