• 論文の詳細を見る

• Seven paraquat resistant calluses of tobacco (Nicotiana tabacum L. cv. Samsun) were obtained by three successive screenings of protoplast-derived calluses on a paraquat containing medium. Superoxide dismutase (SOD) activity of the resistant calluses was 14- to 159-fold that of the leaf cells on protein basis. Paraquat-resistant calluses, however, showed little increase in catalase and peroxidase activities. More than 90% of SOD activity in the resistant calluses was inhibited by KCN, as was the SOD activity in leaves, indicating that the major SOD in the callus appears to be the Cu, Zn containing enzyme. The callus cells, however, expressed the immunologically distinguished SOD isozyme from the enzyme in the leaves.
