Biodiversity Evolution of a Shrub Betula nana L. Populations in the Urals
International Journal of Forestry Research, Volume 2024, Issue 1, 2024.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.
