Research Overview

Higher plants survive by greatly changing their metabolism, consisting of photosynthesis and accompanying carbon dioxide fixation, during the daytime when they are exposed to light and during the nighttime when they are not exposed to light. Chloroplasts are organelles that fulfi ll a very important role during plant photosynthesis and they are also necessary to allow a plant to adapt to the dramatic environmental changes that take place between nighttime and daytime. Our research seeks to uncover how these chloroplasts allow plants to adapt to the light environment changes that occur between daytime and nighttime and how they regulate the metabolic reactions within cells. This kind of control mechanism is generally called a redox regulation. In order to clearly understand the physiology and molecular mechanisms of the redox regulation of higher plant chloroplasts, we are using plant materials such as those of the genus Arabidopsis and employing various methods including physiological and biochemical methods in our research.
