- 論文の詳細を見る
Cd-tolerant (CCd1) cells of carrot (Daucus carota) were selected from wild (CW) cells under 100μM Cd. In the CW and CCd1 cells, the maximum activity of superoxide dismutase was found 1 day and 4 days after Cd treatment, respectively. The activity of ascorbate peroxidase in the CW and CCd1 cells decreased by 80-160 and 160μM Cd, respectively. The activity of glutathione reductase in the CW cells decreased drastically by Cd; whereas, the activity in the CCd1 cells increased. The content of ascorbate in the CW cells decreased remarkably when the Cd treatment was applied, while that in the CCd1 cells also decreased at 4 days but then recovered at 8 days after the Cd treatment. We speculate that Cd tolerance in the CCd1 cells is due to the high activity of glutathione reductase and maintenance of the content of ascorbate.
