mll transcription is responsive to neodymium and iron. (A) Fluorescence of mll promoter fusion strain, ΔmxaF/pAZ6 in response to neodymium addition and neodymium solubility. Bars represent the mean of three replicates and error bars represent SD. (B) Fluorescence of mll promoter fusion strains, ΔmxaF/pAZ6 (black) and WT/pAZ6 (white), in response to iron limitation. Bars represent the mean of three replicates and error bars represent SD. All values have had background fluorescence of an empty vector control subtracted.
