Abstract The localization of peroxidase in cells of horse-radish (Armoracia lapathifolia Gilib.) tumour and teratoma tissues was studied. Both tissue lines were derived from the same primary crown-gall tumour induced on the leaf fragments by a wild type of Agrobacterium tumefaciens B6S3. Enzymatic activity was measured in cell walls, high-density heterogeneous membrane fraction, microsomal and soluble (no particulate) fractions. The subcellular localization of enzymatic activity was distinct for each transformed tissue. Both tumour and teratoma showed similar isoenzyme patterns, but one soluble acidic isoperoxidase could be considered as a marker of cell differentiation.
