Genes successfully targeted in C. reinhardtii or other species to improve photosynthetic productivity. Improvement of CO₂ fixation targets: RuBisCO, RuBisCO activase, LCI (Low-CO₂ Inducible protein), SBPase (sedoheptulose1,7-biphosphatase), FBPase (fructose-bisphosphate aldolase). Optical density reduction: cpSRP pathway (chloroplast signal recognition particle), TLA1 (Truncated Light-Harvesting Antenna 1), LhcbM, NAB1 (nucleic acid binding 1 protein) and CAO (Chlorophyllide a Oxygenase). Green arrows indicate the over-expressed genes, yellow arrows the down-regulated genes and red crosses indicate the knocked-down genes.
