Phosphorus Compounds, Nuclease, and Phosphatase Activities in Healthy and Tumorous Stem Tissues1Datura stramoniumL.

Abstract

The phosphorus compounds, nuclease, and phosphatase activities in healthy and tumorous stem tissues of Datura were compared. The very high level of P in the tumours comes from increased amounts of acid-soluble phosphorus, lipid-phosphorus, ribonucleic acid phosphorus, and deoxyribonucleic acid phosphorus. The activities of ribonuclease, deoxyribonuclease, and glycerophosphatase were all considerably higher in the tumours than in the stem tissue.
