We generated a CPD photolyase knock-down in by RNAi to investigate the role of CPD photorepair for protection of plants from solar UV. These knock-down lines exhibited hypersensitivity to UV-B and an increased occurrence of mutation induced by UV-B radiation compared with proficient in CPD photolyase. These results indicate that CPD photoreactivation plays an important role for UV resistance of and suppression of UV-induced mutagenesis.
