In a study of various phytopathogenic fungi, we found that fungi that belong to the genus Rhizoctonia produce IAA efficiently from tryptophan. R. solani Kuhn MAFF-305219, in particular, produced large amounts of tryptophol (Tol), which was assumed to be a specific by-product of the indole-3-pyruvate (IPy) pathway, in addition to IAA. Therefore, this fungus seemed suitable for analysis of the function and the regulation of the biosynthesis of auxin by a fungal pathogen. Under normal aerobic conditions, the ratio of IAA to Tol synthesized by this strain was higher than that under less aerobic conditions. In metabol-ic studies with various indole derivatives, R. solani converted L-tryptophan and indole-3-acetaldehyde to IAA and Tol, but other indole derivatives were scarcely metabolized. These results suggest that both IAA and Tol are synthesized from tryptophan through the IPy pathway in Rhizoctonia.
