Abstract Indole-3-acetic acid (IAA) was identified and quantitated in spent media from cultures of ten Ustilago maydis strains. IAA was identified by thin-layer chromatography, high performance liquid chromatography (HPLC) and u.v. spectroscopy, and was quantitated by HPLC. All strains produced IAA in a tryptophan (Trp)-supplemented minimal medium at levels of 0.1 to 4.0 μg IAA/ml of spent medium as assessed by HPLC. The highest levels of IAA were found in strains I2 and P2. The latter was also capable of producing IAA without addition of Trp to the medium.
