Hydrotropism and elongation of miz2 and wild-type (WT) roots. A and B, Hydrotropic curvatures of WT (A1–A5) and miz2 (B1–B5) roots at 0 h (A1 and B1), 2 h (A2 and B2), 4 h (A3 and B3), 8 h (A4 and B4), and 12 h (A5 and B5) after the start of hydrotropic stimulation. The arrow (g) indicates the direction of the gravitational force. Scale bars = 1 mm. C and D, Time course of hydrotropic curvature (C) and elongation (D) of miz2 and WT roots. White circles, WT roots; black circles, miz2 roots. Data represents the means ± sd of three independent experiments (n = 20 for each experiment). Asterisks indicate statistically significant differences, as determined by the Student's two-tailed t test (P < 0.01).
