Abstract
[14C]Acetate, [14C]formate, and methyl[14C]methionine all serve as precursors of pyrenocines A, B, and C when added to cultures of Pyrenochaeta terrestris (Hansen) Gorenz, Walker, and Larson, the pathogen responsible for disease known as pink root of onion (Allium cepa L.). This information supports the hypothesis that these metabolites are methyl-substituted polyketides in origin. Pyrenocine A arises from acetate via uncharacterized intermediates and is subsequently converted to pyrenocine B. The biosynthetic role of pyrenocine C remains uncertain.This publication has 0 references indexed in Scilit:
