Research introduction

The plant cell is composed of various subcellular compartments. To coordinate and regulate all these subcellular compartments to function as a single unit, a large number of molecules must be involved in these complex processes. Therefore, we are trying to isolate and characterize important molecular players of these processes by molecular, biochemical, and cellular approaches.
We have discovered and characterized many important proteins in various steps of intracellular trafficking pathways and elucidated the molecular mechanisms of protein trafficking. Endocytosis is another important area of our research. Now, we are trying to understand how abiotic and biotic stress responses are regulated by protein trafficking and endocytosis. In addition, we are also actively studying molecular mechanisms of protein targeting to chloroplasts and mitochondria. We started to elucidate the cytosolic events involved in protein targeting to chloroplasts and mitochondria. Furthermore, by deciphering the protein targeting mechanisms to these endosymbiotic organelles, we are trying to understand the evolution of these organelles. Another important research topic is to develop molecular and cellular tools to develop the plant cells as a protein production system for valuable proteins.
