Iron deficiency-induced phytosiderophore release by B73 and Mo17. Plants were grown in nutrient solution containing 100 μM P and 100 μM Fe (Fe100P100) or no Fe (Fe0P100). The whole system was cultivated under axenic conditions. Root exudates were collected three times over a period of 6 h and pooled prior to HPLC analysis of deoxy-mugineic acid (DMA). Bars indicate mean values ± SD, n = 5. Different letters denote significant differences at p < 0.05.
