<p>A genetic system utilizing the light-regulated expression of the Arabidopsis thaliana chalcone synthase (CHS) gene is described. Two elements within the CHS control region have been identified which are capable of promoting the expression of an operably linked gene, in a plant, in response to stimulation by light. Using these sequences it is possible to create transgenic and chimeric plants which contain one or more exogenously supplied gene whose expression can be inducted by blue, UV or high intensity light.</p> |
