| Outline of Final Research Achievements |
Environmental contamination by hazardous metals is often observed as multi-metal contamination. Although phytoremediation, a plant-based environmental restoration technology has been focused as a promising technique with less adverse effects on environments, development of plant resources suitable for remediating multi-metal contamination is desired. Our previous studies demonstrated that ectopic expression of a bacterial broad spectrum transporter MerC in membrane fractions of Arabidopsis plant cells was a useful tool for accelerating phytoremediation of metals such as mercurials and cadmium. In this study, we applied several plant cell-type specific promoters and generated Arabidopsis plants expressing MerC in specific cell types which were known as crucial for metal or ion uptake and distribution within plants. Analyses of these transgenic lines suggested that expression of MerC-fusion proteins improved various metal accumulation as well as toxic metal tolerance.
