Outline of Final Research Achievements

Molecular mechanism of hyper accumulation of strontium (Sr) by a green macroalga, Bryopsis maxima was analyzed in terms of its element analyses, membranous protein analyses, and expressed sequence tag analyses. In this study, a novel Sr-binding protein was identified. In addition, we found that the most of radioactive-Sr that have been incorporated into thalli were bound with low molecular weight soluble-substance. We developed a method for determination of this Sr-binding substance using cationic ion-exchange chromatography. These results are an important step toward the production of future phytoremediator plants that highly accumulates environmental strontium.
