Physiological and biochemical effects of morphactin IT 3233 on callus and tumour tissues of Nicotiana tabacum L. cultured in vitro. IV. IAA oxidase activity. Oat coleoptile biotest
IAA oxidase activity in callus and tumour tissue of tobacco subjected to the action of morphactin IT 3233 for shorter and longer periods was determined. Control tumour tissue shows an activity higher by about 40 per cent as compared with that of callus tissue. Morphactin applied for a short time (24...

| description | IAA oxidase activity in callus and tumour tissue of tobacco subjected to the action of morphactin IT 3233 for shorter and longer periods was determined. Control tumour tissue shows an activity higher by about 40 per cent as compared with that of callus tissue. Morphactin applied for a short time (24-h incubation) does not change the activity of the enzyme. When application is prolonged, a considerable enhancement (up to 140%) of the enzyme activity in callus tissue is observed in dependence on the morphactin concentration. In tumour tissues the activity is stimulated by 45 per cent as compared to control. Oat coleoptile elongation growth induced by IAA is limited to 40 per cent when morphactin is added in the concentrations used for tobacco tissue cultures. The possibility of the morphactin action on tissue growth via IAA metabolism is discussed. |
