## Summary In light‐, but not in dark‐grown spinach seedlings, the mRNAs for the nuclear‐encoded photosystem I subunits D, F and L are associated with polyribosomes and this association is prevented by the application of 3‐(3′,4′‐dichlorophenyl)‐1,1′‐dimethyl urea (DCMU), an inhibitor of the photosynthetic electron transport. To identify the __cis__‐elements which are responsible for this regulation, we generated a series of chimeric __PsaD__ constructs and tested them in transgenic tobacco. The spinach __PsaD__ 5′‐untranslated region is sufficient to confer light‐ and photosynthesis‐dependent polyribosome association onto the __uidA__ reporter gene, while the tobacco __PsaD__ 5′‐untranslated region directs constitutive polyribosome association. These results are discussed with regard to signals from photosynthetic electron flow which control processes in the cytoplasm.
