Quorum sensing negatively controls type III secretion regulon expression in Pseudomonas aeruginosa PAO1.
A systematic analysis of the type III secretion (T3S) genes of Pseudomonas aeruginosa strain PAO1 revealed that they are under quorum-sensing control. This observation was supported by the down-regulation of the T3S regulon in the presence of RhlR-C4HSL and the corresponding advanced secretion of ExoS in a rhlI mutant.
