Fig. 3From: The Antarctic sea ice alga Chlamydomonas sp. ICE-L provides insights into adaptive patterns of chloroplast evolutionA hypothetical scheme for limitation of photosynthesis under salt stress. When the Rubisco is inactivated by high salt stress, the photosynthetic fixation of CO2 is limited. The depletion of NADP+ leads to electrons transferring to O2. The excess ROS (reactive oxygen species) can damage the PSI and inhibit the repair of PSIIBack to article page
