Abstract:Genetic polymorphism of B. nana along the Ural ridge is analyzed based on the variability of trnS-trnG, trnL-trnF, trnS-trnT, trnK1-trnK2, and matK1 cpDNA markers with the application of the RFLP method. Specimens of B. pubescens were additionally taken for comparative analysis. The research revealed 12 chlorotypes in B. nana and B. pubescens populations, among which chlorotypes A and B were the most frequent. The Polar Urals populations are characterized by prevailing chlorotype A, significantly decreased gen… Show more
