Outline of Final Research Achievements

The plant cell wall has a complicated structure in which various polymeric materials interact with each other, and the details are not clarified. Each component constituting the cell wall is synthesized by the enzyme of the cell and then complexed by self-assembly to construct a complicated cell wall structure outside the cell. On the other hand, organisms such as mushrooms that grow with the cell wall as a nutrient source acquire nutrition by decomposing the complicated structure of the cell wall by the degrading enzyme. Therefore, in this study, the relationship between the enzymes of these organisms and the organization of components constituting the cell wall was clarified by microscope technology and biochemical technology, and knowledge was obtained for understanding and utilizing complex plant cell wall.
