ResumoChlamydomonas reinhardtii cultured under salinity conditions displays lower rates of cell growth and correspondingly lower rates of light-saturated photosynthesis. Salinity does not exert adverse effects on the stoichiometry and chlorophyll antenna size of the two photosystems. However, salinity-stress enhances substantially the susceptibility of cells to photoinhibition. This arises due to the lower light-saturated rates of photosynthesis under salinity-stress (direct-effect), and due to a salinity-induced inhibition of the recovery (repair) of cells from the photodamage (indirect effect).
