A new metabolite of the plant growth substance indole-3-acetic acid has been extracted from Zea mays seedlings and characterized as the 7'-O-beta-D-glucopyranoside of 7-hydroxy-2-oxindole-3-acetic acid. This compound was the major product formed from [5-3H] 2-oxindole-3-acetic acid, incubated with intact plants or root and coleoptile sections. Identification was by gas chromatography-mass spectrometry of the trimethylsilyl derivative and by analysis of the hydrolysis products. A synthesis is reported for 7-hydroxy-2-oxindole-3-acetic acid. These results and prior work demonstrate the following catabolic route for indole-3-acetic acid in Zea: indole-3-acetic acid—-2-oxindole-3-acetic acid—-7-hydroxy-2-oxindole-3-acetic acid—-7-hydroxy-2-oxindole-3-acetic acid glucoside. |
