| Research Abstract |
Willow(Salix sp.) plants have the capability to take up high levels of toxic metals. In this work, I have investigated the phytoremediation potential of the willow plants to clean up the metal pollution in the environment. Several accumulation sites in the plant body and speciation of the endogenous metals were identified by using physicochemical evidences including synchrotron-radiation based X-ray microanalyses. Tissue specific cDNA libraries were constructed to identify the genes for metal accumulation and detoxification. Willow plants growing near an old mining site was also examined to evaluate the metal accumulating ability of this plant in the field.
