[Retracted] Superoxide-Dismutase Deficient Mutants in Common Beans (Phaseolus vulgaris L.): Genetic Control, Differential Expressions of Isozymes, and Sensitivity to Arsenic

Figure 3

Inhibition (KCN, H₂O₂, and NaN₃) study and visualization of SOD isoforms in native PAGE of leaf extracts of Phaseolus vulgaris cv. VL 63 (mother variety) and two SOD-deficient mutant lines, sodPv 1, and sodPv 2; lane 1: mother control (no inhibitor), lane 2: mother variety (KCN), lane 3: sodPv 1 (KCN), lane 4: sodPv 2 (KCN), lane 5: mother variety (H₂O₂), lane 6: sodPv 1 (H₂O₂), lane 7: sodPv 2 (H₂O₂), lane 8: mother variety (NaN₃), lane 9: sodPv 1, and lane 10: sodPv 2. Note that complete absence of band at lane 7; Mn SOD is absent in sodPv 2 mutant, and Fe SOD and Cu/Zn SODs are inhibited by H₂O₂ treatment.
