TudzynskiBettina 2012 <p>A: Growth ability of the indicated strains on solidified Czapek Dox (CD) medium supplemented as indicated. Representative pictures were taken after 3 days of incubation at 28°C in the dark. B: Phylograms of ferroxidases and iron permeases from <i>F. fujikuroi</i> (Ff), characterized proteins from <i>F. graminearum</i> (Fg) and <i>A. fumigatus</i> (Af), as well as homologous sequences from <i>F. oxysporum</i> (FOXG) and <i>F. verticillioides</i> (FVEG) obtained from the Broad Institute database were created as described in Methods. Scale bars represent character changes. C and D: Northern blot analysis using indicated genes as probes and rRNA visualization as loading control. The indicated strains were grown as described in Methods. (−); addition of water, (+) addition of FeCl<sub>3</sub> to a final concentration of 1 mm.</p>
