Abstract

Hybrid plants were verified in Betula nana populations of the Urals by flow cytometry and were especially numerous in the northern part of the region. ITS1 nucleotide sequences were obtained by Sanger sequencing. Based on their analysis, low differentiation was observed for B. nana and B. pubescens and associated with current and ancestral hybridization processes. Intragenomic polymorphism of ITS1 sequences was assessed using the Illumina technology and detected both B. nana and B. pubescens rDNAs in the genomes of first-generation interspecific hybrids.

乌拉尔地区桦树杂交植物的检测与验证。

利用流式细胞术证实了乌拉尔地区白桦种群中存在杂交植物，其中乌拉尔北部白桦种群数量较多。Sanger测序获得ITS1核苷酸序列。根据他们的分析，雌雄同体的分化程度较低，这与现在和祖先的杂交过程有关。利用Illumina技术分析了ITS1序列的基因组内多态性，并在第一代种间杂交的基因组中检测了小白蚁和短毛白蚁的rnas。
