General Information

General Information Comment Organism
physiological function cells grow increasingly faster at higher light intensities from low to high to extreme by escalating photoprotection via shifting from linear electron flow (PSII-LEF) to cyclic electron flow (PSII-CEF) with concomitant PSII charge separation from plastoquinone reduction (PSII-LEF) to plastoquinol oxidation (PSII-CEF). Low light-grown cells have unusually small antennae, use mainly PSII-LEF and convert 40% of PSII charge separations into O2. High light-grown cells have smaller antenna and lower PSII-LEF. Extreme light-grown cells have no LHCII antenna, minimal PSII-LEF, and a doubling time of 1.3 h Chlorella ohadii
