Functional studies of photosynthesis and its related plant metabolism
The main focus of study in our laboratory is photosynthesis and its related metabolism. We are particularly interested in studying chlorophyll metabolism in a wide range of photosynthetic organisms including plants, green and brown algae, cyanobacteria and other photosynthetic bacteria. Chlorophyll is an absolutely essential molecule in photosynthesis: it absorbs light, transfers its energy to other molecules, and finally converts its energy to drive an electron flow. Chlorophyll is necessary for the construction of the photosynthetic machinery on thylakoid membranes As a result, the regulation of chlorophyll metabolism is tightly coupled with the construction and destruction of the photosynthetic machinery.
Furthermore, chlorophyll metabolism affects greening, leaf development, senescence and ultimately plant cell death. The mechanisms pertaining to how chlorophyll metabolism influences such a variety of cellular activities are currently under investigation. It is possible that plants take advantage of the unique properties of chlorophyll molecules, and their biosynthetic intermediates, and use these molecules to enable the control of various biological processes.
Recently, we are further expanding the area of research. Our research projects include the following topics:
1. Acclimation of photosynthetic organisms including herbs, evergreen trees, mosses, green algae and cyanobacteria to various environments such as low temperatures
2. Evolution of photosynthetic organisms.
3. Biogenesis of photosystems.
4. Chlorophyll biosynthesis and breakdown
5. Regulation of nitrogen metabolism in plants
