文摘

The dependence of plant biomass production under UV-A radiation on genotype and/or further environmental conditions is analysed. Protection offered by the leaf structure and/or biochemical composition commonly prevents UV-A induced photosynthetic inhibition. UV-A regulates the accumulation of specific phenolic compounds rather than total phenolics. The overall lack of correlation between UV-A and UV-B effects does imply distinct molecular and physiological responses under the two wavelength bands. The review considers a role of photoreceptors (UVR8, phototropins, phytochromes and cryptochromes) in plant responses to UV-A exposure.
