Two auxin oxidases with distinct antigenic specificities have been identified in extracts of plant tumor induced in Datura stramonium by Agrobacterium tumefaciens. Auxin oxidase and peroxidase activities are demonstrated for both enzymes. The adaptation of an immunochemical method allows the quantitative evaluation of both enzymes in different plant tissue extracts. The amount of these enzymes which is low in the organ of the healthy plant increases during tumorisation, healing and in vitro culture of healthy tissues.
