range, photodamage to plants could be induced by UV comprising 7–9% of the total energy of solar radiation reaching the Earth surface [13]. Shortwave UV (UV-C, wavelengths below 280 nm) is absorbed almost com-pletely by the ozone layer of the atmosphere.

WhatsApp: +86 18221755073Sunlight damages photosynthetic machinery, primarily photosystem II (PSII), and causes photoinhibition that can limit plant photosynthetic activity, growth and productivity. The extent of photoinhibition is associated with a balance between the rate of photodamage and its repair. Recent studies have shown that light absorption by the manganese cluster in the …
