Abstract:

In order to deep understand the effect of iron deficiency stress on photosynthesis in algae, the authors summarized the important role of iron in photosynthetic electron transport chain, and concluded the destruction effect of iron deficiency on photosynthetic elements and the photosynthetic response mechanism of algae. Focused on the photosynthetic electron transport chain, the photosynthetic elements which were easily affected by iron deficiency, such as chlorophylls, photosystems and light-harvesting antennas, were summarized. This study concluded that iron deficiency stress could severely damage chlorophyll biosynthesis and affect the contents, activity and protein stability of photosystem I (PSI), photosystem II (PSII) and their peripheral light-harvesting antennas in algae. Algae can adjust the structure and function between the photosystems and their peripheral light-harvesting antennas by generating new iron-inducible proteins or functional replacement proteins around PSI/PSII to cope with iron deficiency stress.

Key words: iron deficiency stress, photosynthesis, iron-inducible protein, photosystem I, light-harvesting antennas
