FOLLOWING the demonstration that the amino-acid tryptophane can readily be converted by barley plants into the alkaloid gramine1, the study of the biogenesis of alkaloids carried on here has included investigations into the possibility that nicotine may arise from tryptophane in a manner similar to the formation of nicotinic acid in animals and microorganisms2. Recent discussions of this possibility3,4 prompt me to describe part of these investigations.
