Biodiversity Evolution of a Shrub Betula nana L. Populations in the Urals
Genetic polymorphism of B. nana along the Ural ridge is analyzed based on the variability of trn S -trn G, trn L -trn F, trn S -trn T, trn K1 -trn K2, and mat K1 cpDNA markers with the application of the RFLP method. Specimens of B. pubescens were additionally taken for comparative analysis. The res...
