Cycloheximide, actinomycin D, puromycin, 5‐fluorouracil and 5‐fluorodeoxyuridine, all inhibitors of nucleic acid and protein synthesis, have been used to investigate at which level light affects carotenogenesis. The first three compounds inhibited both total protein and total carotenoids whereas the other two inhibited protein but not carotenoids. The results suggest that ribosomal RNA or possibly AMP‐rich RNA must be implicated in the light effect. A scheme involving protein synthesis is proposed to account for the results obtained.
