Аннотация: Using AFLP analysis, the genetic variation in four population samples of Rhododendron ledebourii, three such samples of Rh. dauricum, two samples of Rh. sichotense, and one sample of Rh. mucronulatum was examined. Application of three selective primer pairs provided genotyping of 87 accessions from the four species at 213 loci. An analysis of molecular variance revealed a high level of differences between all four species (F (ST) = 0.172). Populations within the species were also differentiated: for Rh. dauricum F (ST) = 0.245; Rh. ledebourii F (ST) = 0.264; Rh. sichotense F (ST) = 0.034. The highest Nei distance was observed for Rh. mucronulatum with Rh. dauricum and Rh. ledebourii (D = 0.057 and 0.069, respectively). Similarity was observed between the species pairs of Rh. ledebourii-Rh. dauricum (0.032) and Rh. sichotense-Rh. mucronulatum (0.034). The Far Eastern species Rh. sichotense and Rh. mucronulatum were characterized by an elevated level of intrapopulation variation. The data from the AFLP-based analysis of differentiation and variation that were thus obtained were compared with the literature data on the morphological criteria that differentiate the species of interest and those regarding the history of the formation of their ranges. The independence of all the species we examined was confirmed.

Аннотация: The variability of four microsatellite loci of chloroplast DNA was studied in 38 populations of Pinus sylvestris in the European part of Russia, in Siberia, Kazakhstan, Transbaikalia and Mongolia. High variability was observed in all regions. In total, 152 haplotypes were identified. The level of population differentiation R (ST) was 2.1%. The differentiation of three geographical groups of populations (European, Siberian-Kazakhstan and Transbaikalian-Mongolian) was insignificant (R (CT) = 0.004). At the same time, some rare haplotypes were found to be specific for a certain geographical region. Distribution of the rare haplotypes, which differentiated European populations from Asian populations and Mongolian and Transbaikalian populations from the Siberian, showed the independence of the history of these regions. This corresponds more to the hypothesis that the modern area of Pinus sylvestris originated via settlement from many origins than to the hypothesized single center of the post-glacial recolonization. The distribution of the pairwise differences between the individual specimens corresponded to the model of sudden population growth. The assessments of the age of this event for Pinus sylvestris (4.5-4.7 million years), which were obtained on the basis of this model, significantly exceeded the age of the Quaternary. Therefore, the revealed population growth is hardly due to the changes in flora related with the glaciation, but rather mirrors the moment of the species formation.
