The function of microorganisms is very important in human diet. For example, it is well known that traditional Japanese foods such as miso, soy sauce, and sake are brewed by utilizing the fermentation action of microorganisms. In the process of sake brewing, various microorganisms such as lactic acid bacteria beside the koji molds and yeasts, work in concert to influence the quality and flavor of sake. In addition, symbiotic microorganisms have a great influence on the growth of crops such as soybeans and rice, which are raw materials for brewed foods. Aiming for the effective utilization of microorganisms for a rich human diet, I study on the mechanism of such microbe-microbe interactions and plant-microbe interaction from the viewpoint of genetics, ecology, and genomics.

List of current research topics
