Antimutagenic Effect against Colchicine of Kinetin in Black Currant Seedlings

Abstract

IT is generally known that the juvenility of plant organs can be prolonged by treatment with kinetin; moreover, senescent tissues can be rejuvenated¹, and several authors have shown increased mutability of older tissues². Treatment of plant leaves by kinetin appreciably inhibits the multiplication of viruses^3,4, although the virus contains RNA. After incorporation into the host cells, the virus may cause information disturbances by inducing the synthesis of foreign RNA. In this interpretation, the changes brought about by the virus are in the nature of mutations.
