Fig. 2. Native gel stained for the activity of superoxide dismutase (SOD) and identification of SOD isoforms in roots of Penncross and G-6 creeping bentgrass under 21 d of waterlogging treatment (WL). Lanes 1, 2, 3 represent well-drained control (CL), WL at 1 cm below the soil surface (WL-1), and WL at 15 cm below the soil surface (WL-15), respectively. Lanes 4, 5, 6 represent CL, WL-1, and WL-15, respectively. Equal amounts of protein (65 µg) were loaded to each lane. Arrows indicate the isoforms.
