Although UV radiation is a minor fraction of solar energy that reaches the earth’s surface, it significantly affects plants. UV-B radiation affects important biomolecules directly, including nucleic acids and proteins; these molecules absorb UV radiation easily when presenting π electrons, and this absorption can lead to metabolic, biochemical, and morphological alterations, as well as alterations in the genetic material [5, 6].
