Polymorphism of glucose-6-phosphate dehydrogenase enzyme was studied in the Scots pine populations growing in the sites of Bryansk region which were radioactively contaminated as a result of the Chernobyl accident. It was revealed that the frequency of mutations in isozyme loci increased along with the level of a dose rate (7-130 mGy/year) in the sites under the study. Significant changes in the activity of this enzyme did not depend on the level of radiation exposure.
