Description
Summary:An influence of hydroxyurea (HU) on the growth, DNA and RNA contents and protein synthesis in the tobacco tumour tissue culture was studied in comparison with a homologous callus tissue. In conformity with expectations considerable decrease of DNA level in both tissues is a primary effect of HU activity. This results in the growth inhibition and in the secondary metabolic effects; these effects depend not only on the concentration of inhibitor but also on the age of tissue. In spite of some common features the character of these changes shows a distinct differentiation depending on the tissue type. TMs points to specific modifications of the biochemical regulation of growth in a tumour.
