- 논문관련 분야의 소개, 동향, 전망을 설명 When excess light was irradiated on plant leaves, a lot of by-product can be generated such as singlet oxygen and reactive oxygen species (ROS) which are fatal to plant's survival. Therefore plants start to develop protection mechanism to avoid photodamage. The mechanism, so-called non-photochemical quenching (NPQ), dissipates the excess energy as a heat. Although the biological importance of this process was recognized well, the molecular details of this process were totally unknown. We have approached systematically from intact system to individual complexes in photosystem II including LHCII, antenna complexes, and CP minor complexes. We found the charge-transfer (CT) quenching in in vivo thylakoids and succeeded to explore CT quenching in minor complexes (CP29, CP26, and CP24). In this work, we focused on CP29 and tried to find which chlorophyll(s) triggers this CT quenching. We found that A5/B5 coupled chlorophylls and nearby zeaxanthin can generate CT quenching. We proved this chemical process from the biological scale (a few microns) to chemist's scale (a few nanometers). As the efficiency of photosynthesis rebukes the engineering tool to develop artificial solar cell, this photoprotection mechanism might help to design more stable photovoltaic devices. [Figure 1. Structures of Photosystem II in Arabidopsis thaliana.] Actually we finished this experiment more than one year ago and we were hesitating to submit this manuscript to Nature or Science. All of a sudden, other researchers' result about NPQ suggesting different mechanism has come up in Nature, so we decided to submit ours to Science. We didn't have to hesitate any more. In addition, their paper has made our results distinguishable and important. 2. 연구를 진행했던 소속기관 또는 연구소에 대해 소개 부탁 드립니다.
