Effects of salt stress on basic processes of photosynthesis

Salt stress causes decrease in plant growth and productivity by disrupting physiological processes, especially photosynthesis. The accumulation of intracellular sodium ions at salt stress changes the ratio of K : Na, which seems to affect the bioenergetic processes of photosynthesis. Both multiple inhibitory effects of salt stress on photosynthesis and possible salt stress tolerance mechanisms in cyanobacteria and plants are reviewed.

Additional key words: carboxylases; carotenoids; chlorophyll; cyanobacteria; electron transport; eukaryotic algae; NaCl; photophosphorylation; photosynthetic rate; photosystems; phycobiliproteins; salt tolerance
