Metabolism of Indole-3-acetaldehyde, IV, Electron Acceptor Studies and Physiological Significance of the Aldehyde Oxidase of Avena Coleoptiles
In many higher plants, indole-3-acetaldehyde (IAAld) is believed to be the immediate precursor of the endogenous auxin, IAA. An enzyme system catalysing the oxidation of IAAld to IAA is present in the coleoptiles of Avena. The preparation, partial purification and some characteristics of this enzyme were reported earlier (Rajagopal 1971). This paper records the results of electron acceptor studies in IAAld oxidation and also discusses the physiological significance of the enzyme.
