Glutathione (GSH) is involved in many aspects of metabolism. In our previous work, GSH concentration in the phloem sap collected from oilseed rape plants increased by Cd treatment. These results suggested that GSH might be playing important roles in controlling Cd long-distance transport and accumulation in plants. In this work, we investigated effects of GSH to Cd long-distance transport and accumulation by using positron emitting tracer imaging system (PETIS). After setting two week old oilseed rape plants in the chamber, PETIS experiments were started by adding purified $$^{107}$$Cd in the nutrient solutions which were including GSH. As a result, we succeeded to obtain images of $$^{107}$$Cd accumulation in these plants. $$^{107}$$Cd signals were observed in the shoot and root of oilseed rape plants. In the shoot, Cd accumulation was inhibited by GSH treatment. However, we could not see any difference in the Cd accumulation in the root of oilseed rape plants. Further research enables us to understand effects of GSH on Cd long-distance transport and accumulation.
