Figure 5. A. fumigatus Conidiation Rates in wt and Siderophore Biosynthetic Mutant Backgrounds.

10⁶ conidia of fungal strains were point inoculated in the center of minimal medium plates containing the indicated iron source. Conidia produced by 1 cm² were counted after 120 h of incubation at 37 °C. The wt conidia count was 4.5 × 10⁸. The data represent the means ± standard deviations of results from three independent experiments.
