Quality Control of Photosystem II: Lipid Peroxidation Accelerates Photoinhibition under Excessive Illumination
Environmental stresses lower the efficiency of photosynthesis and sometimes cause irreversible damage to plant functions. When spinach thylakoids and Photosystem II membranes were illuminated with excessive visible light (100-1,000 µmol photons m(-1) s(-1)) for 10 min at either 20°C or 30°C, the optimum quantum yield of Photosystem II decreased as the light intensity and temperature increased. ...
متن کاملQuality control of Photosystem II: reversible and irreversible protein aggregation decides the fate of Photosystem II under excessive illumination
In response to excessive light, the thylakoid membranes of higher plant chloroplasts show dynamic changes including the degradation and reassembly of proteins, a change in the distribution of proteins, and large-scale structural changes such as unstacking of the grana. Here, we examined the aggregation of light-harvesting chlorophyll-protein complexes and Photosystem II core subunits of spinach...
متن کاملLipid Peroxidation in Retinal Homogenates under Illumination
In this study, the effect of photosensitizers on lipid peroxidation in the retina was investigated. Porcine retinal homogenate was exposed to illumination from a fluorescent lamp with or without photosensitizers such as hematoporphyrin, rose bengal, and fluorescein for 60 min. The control, which was exposed to illumination without photosensitizers, did not show a significant increase in lipid p...
متن کاملPhotoinhibition of Photosystem 1
Till recently the term photoinhibition (PI) has been related to PS2 part of photosynthetic electron transport chain, in spite of some publications showing that PS1 can also be inhibited at definite conditions. At chilling temperature and low light intensity PS1 is selectively inhibited while PS2 remains practically unchanged. This review describes the nature of PS1 PI; the differences between P...
متن کاملPhotoinhibition of manganese enzymes: insights into the mechanism of photosystem II photoinhibition.
Evidence has recently been presented that photoinhibition of photosystem II (PSII) is triggered by absorption of light by the oxygen-evolving manganese cluster. To get insight into the effects of light on enzymes containing manganese or other transition metal cofactors, the photosensitivities of Mn catalase, Mn superoxide dismutase, the haem (Fe)-containing bovine liver catalase, and CuZn super...
