Heat maps of Fe-limited and Fe-replete protein changes arranged into functional categories. Each column represents the dilution rates 0.07 day−1, 0.15 day−1, and 0.30 day−1, as indicated. The scale of this heat map is given as log2 change, ranging from −5 (red) to +5 (green) relative to 0.45 day−1. Insignificant changes in protein abundance (P > 0.05) are indicated in gray.
