“…Due to the selective permeability of the membrane, most of the Na + will be blocked outside the chloroplast while a small number of ions accumulate in the chloroplast at low salinity (Chauhan, Singh, Singh, Gour, & Bisen, ; Fujita, Murakami, Aizawa, & Ohki, ; Maathuis, ). However, numerous studies have shown that the chloroplast ultrastructure usually changes in terms of thylakoid membrane swelling, giant starch granules, accumulation of plastoglobules, and decreased organelles, and the chloroplasts even separate from the plasma membrane given an increased concentration of ions (Barhoumi, Djebali, Chaïbi, Abdelly, & Smaoui, ; Fidalgo, Santos, Santos, & Salema, ).…”

Photosynthesis is the largest organic synthesis on Earth, salinity limits crop yield and quality worldwide directly or indirectly related to the decrease in photosynthetic efficiency. The mechanism by which photosynthetic apparatus responds to salt stress is extremely complex and varies with plant genotype, developmental stage, the history of the plant cell and duration of stress imposed. Recent studies have partially revealed the mechanisms from different levels: molecular, physiological and biochemical, morphological; but there is currently no unified mechanism to explain the effect of stress on photosynthesis. This study comprehensively reviews the adaptive mechanism of photosynthetic apparatus under salt stress, summarises methods for increasing the resistance and provides a practical way to increase grain yield in saline soils.

“…This contrasts sharply with the pattern typical of higher plants, where q P falls progressively as the light intensity exceeds the growth light. This cyanobacterial capacity to maintain PS II centers open under excess light reflects a complex and flexible electron transport system (5,44,55,85,86,131,135), as well as a generally high PS I/PS II ratio (23,42,98,112). In particular, cyanobacteria have a very high and flexible capacity to remove electrons from PS II, with oxygen as a terminal acceptor for electron flow from water (21a, 88, 91, 128, 147).…”

SUMMARY Cyanobacteria are ecologically important photosynthetic prokaryotes that also serve as popular model organisms for studies of photosynthesis and gene regulation. Both molecular and ecological studies of cyanobacteria benefit from real-time information on photosynthesis and acclimation. Monitoring in vivo chlorophyll fluorescence can provide noninvasive measures of photosynthetic physiology in a wide range of cyanobacteria and cyanolichens and requires only small samples. Cyanobacterial fluorescence patterns are distinct from those of plants, because of key structural and functional properties of cyanobacteria. These include significant fluorescence emission from the light-harvesting phycobiliproteins; large and rapid changes in fluorescence yield (state transitions) which depend on metabolic and environmental conditions; and flexible, overlapping respiratory and photosynthetic electron transport chains. The fluorescence parameters FV/FM, FV′/FM′,qp,qN, NPQ, and φPS II were originally developed to extract information from the fluorescence signals of higher plants. In this review, we consider how the special properties of cyanobacteria can be accommodated and used to extract biologically useful information from cyanobacterial in vivo chlorophyll fluorescence signals. We describe how the pattern of fluorescence yield versus light intensity can be used to predict the acclimated light level for a cyanobacterial population, giving information valuable for both laboratory and field studies of acclimation processes. The size of the change in fluorescence yield during dark-to-light transitions can provide information on respiration and the iron status of the cyanobacteria. Finally, fluorescence parameters can be used to estimate the electron transport rate at the acclimated growth light intensity.

“…In response to changes in light quantity and quality, cyanobacteria have evolved various regulation strategies to adjust the functions of these three complexes. These strategies include adjusting the total cellular content of the photosynthetic apparatus (Raps et al ., ) and/or the PS I : PS II ratio upon light changes (Myers et al ., ; Fujita et al ., ); redistributing energy from PBS to PS I and PS II during state transitions (Dong et al ., ; Liu et al ., ); and non‐photochemical quenching of excessive light energy by the orange carotenoid protein (Kirilovsky and Kerfeld, ) as well as flavodiiron proteins (Allahverdiyeva et al ., ; Bersanini et al ., ). Furthermore, some cyanobacteria can alter their pigmentation to match the incident light wavelength(s) in their natural habitats.…”
