✦ Synopsis
Timecourse studies were performed which compared the influence of 5-methyltryptophan to tryptophan on alkaloid formation in ergot strain SD-58. Evidence was obtained that confirms the role of tryptophan as an inducer of alkaloid synthesis. Additional studies were conducted to determine the incorporation into protein of the tryptophan analogs: 5-methyltryptophan, 7-methyltryptophan, and 1-N-methyltryptophan, when they are supplied exogenously to the fungus. Incorporation was observed ; however, it was insignificant when compared to the amount of tryptophan incorporated.
