(A) Inhibition study of SOD isozymes produced by double mutant obtained from crosses between sodPv 1 and sodPv 2 mutants of Phaseolus vulgaris L.; lane 1: mother control (no inhibitor), lanes 2 & 3: double mutants (no inhibitor), lane 4: double mutant (KCN), lane 5: double mutant (H₂O₂), and lanes 6 & 7: double mutants (NaN₃). Note that both Cu/Zn SODs I and II were inhibited by KCN and H₂O₂ in lanes 4 and 5, while visualized as, and normal faint bands by NaN₃ at lanes 6 & 7, (B) appearance of necrotic spots (→) on pod wall of double mutant.
