| Research Abstract |
Under fluctuating light conditions, plants have to regulate photosynthesis to sustain its maximum performance and avoid photoinhibition. On the basis of genetics and biochemistry, we clarified many key genes involved in PGR5- and NDH-dependent PSI cyclic electron transport, redox homeostasis in chloroplasts and response to copper deficiency. We further clarified the physiological significance of each regulatory process.
