A switch–rheostat circuit governs quorum sensing homeostasis in a phytopathogen
This study shows that a regulatory element within the pfsR-rsaM intergenic region acts as the primary switch of the PfsI/R QS system, independently of RsaM, and shows for the first time that RsaM is endogenously expressed and functions as a negative regulator modulating the PfsI/R circuit instead of preventing its acti...
