Abstract
Exposure to UV‐B radiation resulted in a loss of chlorophyll and an increase in lipid damage in a similar manner to that induced during natural senescence. In addition, exposure to UV‐B led to the induction of a number of genes associated with senescence (SAG12, 13, 14, and 17). These results show, for the first time, that exposure to UV‐B can lead to cellular decline through active and regulated processes involving many genes also associated with natural senescence.Keywords
