Gene expression in leaves of rice plants submitted for 7 days to control (100 μM Fe+3-EDTA, white bars) or Fe-deficiency (no Fe added, gray bars), evaluated by qPCR. (A) OsZIFL2. (B) OsZIFL3. (C) OsZIFL5. (D) OsZIFL10. (E) OsZIFL7. (F) OsZIFL12. (G) OsIRO2. Values are the averages of three samples ± SE. Statistical differences according to the Student's t-test in comparison to control are shown by one (p ≤ 0.05) or two asterisks (p ≤ 0.01).
