Acetate-1- 14 C and acetate-2- 14 C were supplied to cultures of Gibberellafujikuroi (Saw.) Wr., and the radioactive fusaric acid consequently formed was isolated. Acetate-1- 14 C contributed activity mainly to C-4, C-6, C-7, C-8, and C-10 of fusaric acid, whereas acetate-2- 14 C contributed activity to C-2, C-3, C-5, C-9, and C-11 of fusaric acid. These results are consistent with the hypothesis that fusaric acid is formed from a polyacetate unit and aspartic acid or closely related metabolites.
