UV-B damage amplified by transposons in maize

  title={UV-B damage amplified by transposons in maize},
  author={Virginia Walbot},
While absorbing visible light energy for photosynthesis, plants are unavoidably exposed to ultraviolet radiation, which is particularly harmful at shorter wavelengths (UV-B radiation). Ozone depletion in the atmosphere means that plants receive episodic or steadily increasing doses of UV-B, which damages their photosynthetic reaction centres, crosslinks cellular proteins, and induces mutagenic DNA lesions. Plant adaptive mechanisms of shielding and repair are therefore critical to survival… CONTINUE READING
