Sunlight is a powerful but fluctuating energy source used by photosynthetic organisms to power the assimilation of atmospheric CO2 into reduced carbon compounds. To optimize photosynthetic efficiency in ever-changing light conditions, organisms of the green lineage regulate the distribution of energy input between the two photosystems through state transitions. This process is governed by the redox state of the membrane pool of quinones, liposoluble electron carriers. Through a yet unknown mechanism, the cytochrome (cyt) b6f complex detects these redox changes and transmits a signal to the state transition kinase Stt7 for its activation. In order to decipher the role of the cyt b6f, we devised a novel experimental strategy in Chlamydomonas ...
