| Outline of Final Research Achievements |
The mechanism of thermal dissipation of excess energy of light has been unknown, but by purifying and examining the PSII-LHCII supercomplex from a green alga Chlamydomonas reinhardtii grown in high light, it was clarified that the LHCSR3 induces non-photochemical quenching and that LHCSR1 transfers excess energy to PSI. Furthermore, the gene expression analysis of the high light-inducible LHCSR3 and the UV-inducible LHCSR1 revealed their signal transduction pathways. We also developed a new purification method using amphipol, an amphiphilic polymer, and revealed the structure of the PSII-LHCII supercomplex for the first time.
