Key Points

To examine the genetic structure and diversity of multiple Betula species across different latitudes in China.
Analyzed genetic diversity among six Betula species
Investigated genetic admixture across varying ploidy levels
Explored the role of historical climatic factors in shaping genetic patterns.
Higher genetic diversity observed in northern Betula populations
Evidence of glacial refugia at higher latitudes
Identification of interspecific hybridization and admixture among species.

Abstract

Higher genetic diversity in northern populations of the six Betula species suggests the existence of glacial refugia at higher latitude. The comprehensive dataset for six Betula species not only enables investigation of patterns of genetic admixture across ploidy levels but also fosters novel hypotheses regarding the origins of polyploid lineages and the factors influencing the dynamics of interspecific hybridization.
