The effect of ZnII and CdII on P. fluorescens growth. Growth of P. fluorescens Q2-87 and the ΔMT mutant was compared by optical density measurements at 600 nm upon addition of 50 μM ZnII or 25 μM CdII. Data are presented as the mean of three independent experiments and the standard deviation is given as error bars. See Supplementary Figure S5 for linear growth scale.
