This study identifies new transporters for citrate and cis-aconitate in Pseudomonas aeruginosa and clarifies the role of the TctDE system in regulating their expression.

This study identifies how carbohydrate source and PepO modulate bimodal comX expression in Streptococcus mutans, revealing mechanisms controlling competence development.

This study shows that S. mutans can activate comX through intracellular positive feedback loops involving ComS/XIP, independent of extracellular signals.

This study demonstrates that XIP from Streptococcus mutans functions as an intercellular signal, showing diffusibility and signaling without cell-to-cell contact, with cell lysis enhancing its release.
