The paper shows that constitutive expression of flagellar proteins is necessary for proper flagellation in Shewanella putrefaciens, revealing a 'tier zero' of basal expression required for flagellar synthesis.

This study identifies VbdR as a regulator of Vibrio cholerae biofilm dispersal, showing it induces type IV pilus retraction and matrix protease expression to release cells from the biofilm matrix.

This study identifies ArcZ, an Hfq-dependent sRNA, as essential for small molecule production in entomopathogenic bacteria, revealing its broad regulatory role beyond secondary metabolites.

This paper compares the quorum-sensing systems of Vibrio campbellii DS40M4 and BB120, finding genetic and functional differences in autoinducer production, regulatory mechanisms, and regulon size.
