In our lab, we are focusing on plant mineral stress tolerance and mineral transport system in plants. We have identified a number of Al tolerance genes in rice and barley. Recently we also have elucidated the mechanisms regulating the expression of Al-tolerance genes. Many genes involved in uptake, translocation, distribution and redistribution of mineral nutrients including Fe, Zn, Cu, Mn and Si have been identified in rice and other plants. Furthermore, transporters for toxic elements such as As and Cd have also been identified. Our goal is to improve productivity and safety of crop through our research.
