Abstract
Shoot formation in tobacco (Nicotiana tabacum L.) callus is accompanied by an increase in peroxidase activity which takes a form similar to a sigmoid curve. The “stationary” phase coincide with the period of organ formation. Characteristic changes in isoperoxidase pattern are found in the shoot-forming part of the callus. These changes are different from those in the nonshoot-forming part or in gibberellin-treated tissue, which does not form shoots.Keywords
