Abstract

Variability of nuclear microsatellite loci was examined in Siberian dwarf pine. Six microsatellite loci (RPS2, RPS6, RPS12, RPS124, RPS127, Pc18) demonstrated different polymorphism levels in ten populations of Siberian dwarf pine. The average number of alleles per locus was 4.88, the average observed heterozygosity was 0.465, and the average expected heterozygosity was 0.510. About 13% of total genetic variability was explained by the genetic differences between the populations (F ST = 0.129). Genetic distances between the examined populations of Pinus pumila inferred from the data on the SSR marker frequencies statistically significantly correlated with the geographical distances between the population samples. The level of genetic variability of the populations from Kamchatka Peninsula was lower than that demonstrated by continental and island populations. The genetic differentiation of the Kamchatka–Magadan and other populations of Siberian dwarf pine observed in our study can be explained in terms of their formation from different Pleistocene refugial centers.
