The spectral composition of sunlight in natural aquatic habitats depends on the depth of submergence and the solar time. Changes in the fractional amount of far-red light (FRL) in the total photon flux are associated with the redistribution of light energy absorbed by the two photosystems of photosynthesis. Experiments with a culture of Scenedesmus quadricauda revealed the influence of FRL preillumination on photosynthetic electron transport and associated processes in microalgae. The plant efficiency analyzer M-PEA-2 was used to measure simultaneously the induction curves of prompt fluorescence, delayed fluorescence, and the redox transients of chlorophyll P700. The results are discussed in terms of the action of FRL preillumination on cyclic and noncyclic electron flows with account for relocation of the mobile light-harvesting complex of photosystem II during reversible State 1–State 2 transitions. Essential similarities and substantial distinctions have been revealed in the effects of FRL on photosynthetic electron flows in microalgae and higher plant leaves.
