Abstract

The activity of polyphenol oxidase (PPO) and PPO isoenzymes in the crown gall tumors occured in vivo have been examined in pea. It has been observed that PPO activity in crown gall tumor tissues has been increased more than in the normal tissue. This activity of PPO is similar to increase that was observed in auxin treatments. In addition, it has been observed that PPO isoenzymes number in tumor tissue have also been increased in comparison with the number observed in the control application.
