Fig. 4: Independent regulation of amplitude and period.

a Independent regulation of amplitude. Sixteen groups of single cells were shown as four curves vary with different salicylate concentrations. The four curves respectively represent the IPTG concentration of 0, 2.5, 5, and 10 μM. b Independent regulation of amplitude. The same sixteen groups of single cells were shown as four curves vary with different IPTG concentrations. The four curves respectively represent the salicylate concentration of 0, 50, 100, and 200 μM. Each group had the results of three independent experiments and each experiment had over 100 single cells. The data point were calculated from the average of the three experiments and the error bars were calculated from the SD of the average of the three experiments.
