Fig. 7. — Impact of reduced Fe in gel in combination with Pi delivery on plant growth. High Fe is standard medium (50 μM) and low is 2.5 μM. (A) Root hair length and density measured as previously described (n=30 plants per treatment). (B) Root architecture measurements (n=30 plants per treatment). (C) Gene expression of genes known to be modulated by both Pi and Fe supply (n=20). All plants were grown under high Fe (50 μM). (D) Shoot Fe content determined via ICP-MS (n=5) from plants grown under high Fe (50 μM).
