From: Copper selects for siderophore-mediated virulence in Pseudomonas aeruginosa

Fig. 1

Per capita pyoverdine production (log10-transformed standardised fluorescence units per OD600) by Pseudomonas aeruginosa populations after growth in different concentrations of copper for (A) two days + one day in the absence of copper, or (B) twelve days + one day in the absence of copper. Circles show individual replicates (n = 6), with colour indicating total pyoverdine production (relative fluorescence units) and size showing optical density at 600 nm. Asterisks indicate significant differences between groups (*** = 0.001, ** = 0.01, * = 0.05, NS = non-significant), with the left value comparing the control to the low copper treatment, the middle value comparing the control to the high copper treatment and the right value comparing the low and high copper treatments
