Impact of growth limiting nutrients on P tad1 activity. Specific promoter activity (GFP over biomass, normalized against the wildtype) for U. maydis P tad1- gfp cultivated in MTM containing 0.5 g L−1 KH2PO4 with 0.8 g L−1 (green), 1.6 g L−1 (blue), and 3.2 g L−1 (black) NH4Cl, and 0.1 g L−1 KH2PO4 with 3.2 g L−1 NH4Cl (red). Single values are shown for two biological replicates (n = 2; diamonds) and the mean value (line)
