**6. Conclusions**

Thus, despite the barrage of damage resulting from solar UV exposure plants face every day, they have a variety of mechanisms which allow them to survive. UV induced DNA damage is repaired by direct photoreactivation via photolyases, or by dark repair (NER) in both transcribed (TC-NER) or non-transcribed regions (GG-NER). Finally, rather than repair UV damage, plants can tolerate its presence and proceed with DNA replication via translesion synthesis, although there can be mutagenic consequences of this activity. The continued study of these pathways and the interplay between them in plants is sure to bring additional insight.
