[Effect of chronic irradiation on the genetic structure of natural populations of Arabidopsis thaliana (L.) Heynh].
The genetic structure of Arabidopsis thaliana populations from in the Chernobyl zone of radioactive contamination was studied. The dynamics of genotypic and allele frequencies of eight polymorphic loci were described. Analysis of the results obtained and earlier data revealed selection for loci Per1 and Acp2. Sharp fluctuations of allele frequencies were observed in consecutive generations of chronically irradiated A. thaliana populations. These fluctuations led to replacement of the most frequent alleles, including those close to fixation.
