Tropism analyses of Col-0 and dao1-1. Gravitropic bending assay: 5-d-old seedlings grown on plates were rotated 90°, and images were taken at 3 and 10 h. Phototropism assay: 3-d-old postphotomorphogenic seedlings grown on sand slurry were treated with unilateral blue light, and images were taken every 5 min (n ≥ 10). Asterisks indicate statistical significance (Student’s t test). **P < 0.01.
