The application of genetic and biochemical approaches in Arabidopsis has generated new insights into the photoreceptors and signal transduction processes that mediate the effects of UV and blue light on gene expression and development. Biochemical studies with an Arabidopsis cell culture have provided information on the signal transduction events that couple UV‐B and UV‐A/blue light perception to transcription of the chalcone synthase ( CHS ) gene. Interactions between UV‐B and both UV‐A and blue light signalling pathways enhance the level of CHS transcription. Mutants which identify negative regulators of CHS transcription in response to UV and blue light have been isolated. The integration of biochemical and genetic approaches will further advance understanding of UV and blue light perception and signal transduction.
