**7. Conclusions**

The effects that UV radiation causes on plants have been extensively investigated from different perspectives. Studies on alterations in photomorphogenesis, primary metabolism, particularly photosynthesis, secondary metabolism, or gene expression have been carried out with model plants such as *Arabidopsis thaliana*; however, several other aspects still need to be addressed. Current technologies, such as omics tools, allow for the study of plants in their natural environments, considering all their complexity, and will, undoubtedly, lead to a better understanding of the impact of UV radiation in plants, an important constituent of climate change. Looking into the future, an integral view of plant responses to UV radiation has broad applications in agriculture and conservation, while providing scientific foundations for upcoming international regulations.
