What is Plant Responses to UV Radiation and Links to Pathogen Resistance about?

Increased incident ultraviolet (UV) radiation due to ozone depletion has heightened interest in plant responses to UV because solar UV wavelengths can reduce plant genome stability, growth, and productivity. These detrimental effects result from damage to cell components including nucleic acids, proteins, and membrane lipids. As obligate phototrophs, plants must counter the onslaught of cellular damage due to prolonged exposure to sunlight. They do so by attenuating the UV dose received through accumulation of UV-absorbing secondary metabolites, neutralizing reactive oxygen species produced by UV, monomerizing UV-induced pyrimidine dimers by photoreactivation, extracting UV photoproducts from DNA via nucleotide excision repair, and perhaps transiently tolerating the presence of DNA lesions via replicative bypass of the damage. The signaling mechanisms controlling these responses suggest that UV exposure also may be beneficial to plants by increasing cellular immunity to pathogens. Indeed, pathogen resistance can be enhanced by UV treatment, and recent experiments suggest DNA damage and its processing may have a role.
