Phenotypic analysis of Oryza sativa and Oryza rufipogon plants grown under control (CC) and Fe deficiency (−Fe) conditions. Four week-old plants were grown with or without Fe for up to 9 days. (A) Shoot length (cm) (n = 10). (B) Shoot dry weight (g) (n = 10). (C) Root dry weight (g) (n = 10). (D) Chlorophyll concentration (µg mg⁻¹ DW) (n = 4, 3 plants each). The x-axis represents days after onset of −Fe treatment. Values are the averages ± SE. Asterisks indicate statistical difference between plants grown under CC and −Fe conditions (Student t-test, *P-value < 0.05, **P-value < 0.01, ***P-value < 0.001, ****P-value < 0.0001). DW = dry weight.
