「Regulation of Cyclic electron flow, A to Z」

Organizers

Hiroko Takahashi (Saitama Univ.), Ginga Shimakawa (CNRS)

Photosynthetic electron transport is an essential process for converting light energy to chemical energy. While liner electron flow from water to NADP+ generates both NADPH and ATP, the cyclic electron flow around photosystem I can generate only ATP, but it is important to achieve balance of the ATP/NADPH ratio for the Calvin-Benson cycle and to induce photoprotection under stress conditions. Although the phenomenon of cyclic electron flow was defined more than 50 years ago and many studies have contributed to revealing the molecular mechanisms, the details are still controversial. Here we organize the symposium focusing on the cyclic electron flow. The symposiasts will present the latest data related to the methodology for evaluating the cyclic electron flow, the diversity of the cyclic electron flow among the organisms, and the hypotheses to revisit the molecular mechanisms and regulations of the cyclic electron flow.
