Fold Variation of FBA Gene Expression Observed in Fe-Limited Cultures with Respect to Fe Replete Cultures (5 nM vs. 10 μM).

	Experiment 1	Experiment 2
FbaC1	26.1 ± 2.2	45.3 ± 5.2
FbaC2	−22.9 ± 0.7	−36.0 ± 33.5
Fba3	13.0 ± 3.1	16.7 ± 2.9
Fba4	1.2 ± 0.2	1.4 ± 0.2
FbaC5	86.4 ± 23.9	100.8 ± 28.0

Note.—Two identical experiments were conducted on different dates; the fold change was calculated by the 2^{−ΔΔ C}T method (see Materials and Methods). The values shown are averages and standard deviations of two replicate mRNA extractions.
