Abstract/Contents: | "The partitioning of Cd between roots and shoots was determined for young plants exposed to Cd in nutrient solution. The intentionally high concentration of 3 uM Cd was used to assess the role of root Cd-binding protein (Cd-BP) in Cd detoxification. The roots of tomatoes exposed to Cd retained 60-84% of the plant Cd from day 2 through day 9 without toxicity symptoms evident. Cd-BP did not contribute to Cd retention over the initial 4 days, only 1-4% of the root Cd was in this protein fraction. Maize roots retained 59-69% of the plant Cd from day through day 7. The Cd-BP fraction bound 8-19% of the root Cd on day 1 and 31-55% by day 7. Cd toxicity symptoms occurred in leaves by 4 days. In the grass Agrostis gigantea the roots retained 73-85% of the seedling Cd after 1 day and for another 6 days. A high proportion of the root Cd (34-68%) was in the Cd-BP fraction after one day and continued to be so to day 7 (46-64%). No Cd toxicity symptoms were evident. Only the specific pattern of rapid, early and sustained production of Cd-BP observed in Agrostis was consistent with the putative detoxification role for Cd-BP." |
