Abstract dl -Ornithine-[2,3- 13 C 2 ] was synthesized from acetate-[1- 13 C] and ethyl acetamidocyanoacetate-[2- 13 C]. This labelled material was mixed with dl -ornithine-[5- 14 C] and fed to Nicotianaglutinosa plants by the wick method. After 10 days the plants were harvested affording radioactive nicotine and nornicotine (0.14% and 0.051% specific incorporations, respectively). Even at these low
