Habituated sugar beet calli have been characterized as having a deficiency in some tetrapyrrole containing compounds. However, peroxidases might be dissociated from the other tetrapyrrole containing compounds. When light-cultured normal and habituated calli were transferred to darkness their peroxidase activity reduced and increased, respectively, indicating that habituation could not strictly be characterized by a deficiency in peroxidase content but rather by a different regulation of its activity. This regulation could be mediated through soluble effectors which act as potential peroxidase inhibitors and/or by a differential expression of the peroxidase isoenzyme patterns which were present in these tissues in both light and darkness.
