    Cyanobacteria are promising green cell factories to produce valuable compounds by directly fixing CO2. The photosynthetic organisms acclimate and adapt to changing light condition by controlling the energy transfer between both photosystems and the pigments composition for keeping a suitable balance of excitation between photosystem I (PSI) and photosystem II (PSII). We try to understand the adaptive function of photosystems of cyanobacteria against various types of light conditions based on systems biology techniques such as genome scale metabolic modeling and 13C-metabolic flux analysis. Evolution engineering to screen high light tolerant strains is also performed to elucidate mechanism of high light stress tolerance.
