Abstract
Indole-3-acetic acid (IAA) was identified and quantitated in spent med ia from cultures of ten Ustilago maydis strains. IAA was identified by thin-layer chromatography, high performance liquid chromatography (HP LC) and u.v. spectroscopy, and was quantitated by HPLC. All strains pr oduced IAA in a tryptophan (Trp)-supplemented minimal medium at levels of 0.1 to 4.0 mu g IAA/ml of spent medium as assessed by HPLC The hig hest levels of IAA were found in strains I2 and P2. The latter was als o capable of producing IAA without addition of Trp to the medium.
