Summary of main research topics

Analysis of genetic and physiological regulation mechanisms for food production
Sustainable agriculture and securing a sufficient supply of food are very important subjects for people living harmoniously in natural environments in the 21st century. This group conducts analyses of genetic factors for greater production efficiency using endogenous transposon and gene introduction or genome rearrangement from wild species in rice. Important seed dormancy in wheat is analyzed genetically and physiologically. In addition, the isolation of genes for tolerance of metal stresses or oxidation stresses in wild plants and their expression analysis are conducted. Furthermore, plants are being developed that can grow in space and in inferior environments on Earth.
