Figure 2

In vitro gene expression of sirR (a, b and c) and sitC (d, e and f) in planktonic bacteria. Gene expression is quantified as log10 (cDNA/gDNA) in the y-axis. The line that links the data points helps to clarify the results at each time point measured. The error bars represent standard deviations. Fifteen samples from three independent cultures were assessed at each time point. Time is given in hours in the x-axis. (a) and (d): bacteria pre-incubated overnight in BHI and incubated in fRPMI (full line with empty circle) or fRPMI-Fe1 (full line with filled triangle). (b) and (e): bacteria pre-incubated overnight in fRPMI and incubated in fRPMI (full line with filled diamond) and in fRPMI-Fe1 (full line with filled square). (c) and (f): bacteria pre-incubated overnight in fRPMI and incubated in fRPMI (dotted line with filled diamond) or in fRPMI-Fe25 (full line with empty triangle).
