Altered Response of the rol5-1 Mutant to ROS and ROS Scavenger.
Seedlings were grown in liquid culture for 10 d. Under control conditions (A), growth of the wild type and rol5-1 is comparable. rol5-1 seedlings are hypersensitive to H2O2 (8 mM), revealed by the reduced growth (B), and hyposensitive to the ROS scavenger CuCl2 (100 μm), indicated by better growth and the development of green cotyledons (C). col, wild-type Columbia.
