[Radiation-induced changes in the cellular chromatin of cereal plants cultivated in the area of the Chernobyl Atomic Electric Power Station].
The changes in chromatin and DNA of seedling and callus tissues of cereals grown in the Chernobyl NPP zones with contamination levels of 15, 40 and 60 Ci/km2 were studied. Test samples produced by germinating and culturing seed cells of grown in contaminated areas were notable for the content of soluble polydesoxiribonucleotides, amount of DNA damages, DNA distribution over separate compartments of cell nucleus as compared to the control. Analogy between radiation-induced changes in chromatine and processes occurring in cell nucleus senescence was observed.
