Fe(III) reductase assays of tobacco roots and shoot segments of 8-week-old plants grown in the greenhouse. A, Roots of control NI-1 (left) and transformant FRE1-C (right) after 6 h in semisolid medium with 25 μm Fe(III)-EDTA and 0.3 mm BPDS. B, Roots of FRE2-B (left) and FRE1+2-A (right) after 6 h in semisolid medium with 25 μm Fe(III)-EDTA and 0.3 mm BPDS. C, Shoot segments of control NI-1 (top) and transformant FRE1+2-A (bottom) after 4 h in semisolid medium with 0.1 mm Fe(III)-EDTA and 0.3 mm BPDS. D, Shoot segments of 10 seedlings of a family segregating for FRE1 in semisolid medium after 4 h in semisolid medium with 0.1 mm Fe(III)-EDTA and 0.3 mm BPDS; PCR analyses of the same seedlings and water control (0) with FRE1 primers are shown at bottom.
