Start behavior. Based on the complexes using minimal initial conditions. The first complex C1 between AI–1 and LasR is shown in red and the second complex C2 between AI–2 and RhlR in blue. The levels averaged over ten different runs for complexes of the pqs system are shown in orange (C3 between PQS and PqsR) and in green (C5 between HHQ and PqsR). Dotted lines denote the first peak of the same colored complex.
