| Outline of Final Research Achievements |
In order to develop technologies for heavy metal phytoremediation, it is important to elucidate the heavy metal tolerance and accumulation mechanism of the hyperaccumulator plants. In this study, we focused on copper mosses Scopelophila cataractae which has copper tolerance and accumulation ability. By using genomic editing technology and transcriptome analysis, we aimed to elucidate the molecular mechanisms underlying copper tolerance and accumulation in S. cataractae. As a result, we found that the mechanism of copper export from intracellular to extracellular via copper transporter ScHMA5 is necessary for copper tolerance ability in S. cataractae.
