Polymorphism ofsuperoxidedismutase in Scots pine populations from the Bryansk region radioactively contaminated as a result of the Chernobyl accident was studied. The frequency of mutations in the isozyme loci, the effective number of alleles, intrapopulation diversity, as well as the frequency of rare morphs were significantly increased along with the level of radioactive contamination. Changes in the genetic makeup of the populations under study were due to the increased frequency of rare alleles.
对布良斯克地区因切尔诺贝利事故而受到放射性污染的苏格兰松种群中超氧化物歧化酶的多态性进行了研究。随着放射性污染水平的升高,同工酶位点的突变频率、有效等位基因数、种群内多样性以及稀有形态的频率均显著增加。所研究种群的基因组成变化是由于稀有等位基因频率的增加。
