Abstract

An indoleacetic acid oxidase preparation from an acetone powder of Parthenocissus tricuspidata crown-gall tissue has been examined. An intermediate in the reaction is 3-hydroxymethyloxindole and nonenzymic conversion of it to 3-methyleneoxindole was observed. Neither reaction mixtures nor 3-methyleneoxindole have any auxin-like activity in Avena or wheat coleoptile bioassays. In vivo studies show that although 53% decarboxylation of indoleacetic acid was observed in 48 hours, only a small amount of 3-methyloxindole could be recovered from the medium. The other decarboxylated products remain to be identified but are not 3-hydroxymethyloxindole or 3-methyleneoxindole.
