This study identifies how CAP and LuxR co-regulate gene expression in Vibrio campbellii through synergistic or antagonistic promoter occupancy, revealing indirect regulation of bioluminescence.

This study identifies PTSP as a ligand that induces proteolytic degradation of SmcR, controlling quorum sensing state transitions in Vibrio species.

This study identifies a dual regulatory mechanism by LuxR in Vibrio campbellii that represses T3SS gene expression through transcriptional and post-translational repression of ExsA activity.

The paper introduces Mobile-CRISPRi, a system for gene knockdown in Vibrio species, showing it effectively modulates gene expression and phenotypes.
