Hypocotyl elongation of rop2 transgenic plants. A, Hypocotyl lengths of 10-d-old seedlings grown on agar plates under higher light intensity (8-h dark/16-h light, 33 μmol m⁻² s⁻¹). B, Hypocotyl lengths of seedlings grown in liquid culture in the presence of 100 nm BR under lower light intensity (8-h dark/16-h light, 20 μmol m⁻² s⁻¹). Filled columns represent 100 nm BR treatment. Blank columns represent hypocotyl elongation without BR treatment. Seedlings were grown in liquid one-half Murashige and Skoog medium plus 1% (w/v) Suc with shaking for 5 d. Error bars stand for sd (n = 20).
