Figure 6. Cdc50 is required for robust growth on heme or inorganic iron sources.

(A) Tenfold serial dilutions of each strain (labeled on the right) were spotted on the indicated media after iron starvation and the plates were incubated at 30°C for 2 days before being photographed. (B) Iron-starved cells of the indicated strains were inoculated in liquid YNB medium plus 150 µM BPS without and with supplementation with iron sources. The cultures were incubated at 30°C, and OD600 was measured.
