Resumo
Using the flow cytometry method, hybrid samples were verified in B. nana populations, most of which were identified in the northern part of the Ural Mountains. Analysis of the ITS1 region nucleotide sequences obtained using the Sanger method showed low differentiation of B. nana and B. pubescens species associated with current and ancestral hybridization processes. Analysis of intragenomic polymorphism of ITS1 sequences using Illumina technology revealed the presence of rDNA of both B. nana and B. pubescens in first-generation interspecific hybrids genome.
