Figures

FIG. 1. — FIG. 1.
Model of P. aeruginosa quorum-sensing network. Black arrows indicate direct transcriptional control (positive/negative or as indicated), blue arrows indicate protein-AHL interactions, and red arrows are protein-protein interactions. Solid arrows are well-supported mechanisms of regulation, while dashed arrows are more tentative. Looped arrows indicate positive feedback on cognate AHL synthesis via LasR and RhlR. Underlying circles represent genes under direct transcriptional control of each LuxR-type protein.
