Because of their dependence on sunlight for photosynthesis, plants are also exposed to the DNA-damaging effects of ultraviolet (UV) radiation. In the 15 March Genes & Development, Roman Ulm of the Friedrich Miescher Institute in Basel and co-workers report on how plants cope with genotoxic stresses, such as UV radiation (Genes Dev 2001, 15:699-709). Ulm et al identified a mutation in Arabidopsis thaliana, mkp1, that results in hypersensitivity to the DNA-damaging agent MMS (methyl methanesul
