title: Ultraviolet-B exposure leads to up-regulation of senescence-associated genes in Arabidopsis thaliana.
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.
