Population Genomics Reveals Demographic History and Genomic Differentiation of Populus davidiana and Populus tremula.

ABSTRACT: Forest trees can increase our understanding of how evolutionary processes drive the genomic landscape and understand speciation due to the majority of forest trees being distributed widely and able to adapt to different climates and environments. Populus davidiana and Populus tremula are among the most geographically widespread and ecologically important tree species in Northern Hemisphere. Whole-genome resequencing data of 41 individuals of P. davidiana and P. tremula throughout Eurasia was conducted, finding that genetic differentiation was evident between the two species, the F_ST values between P. davidiana and P. tremula was 0.3625. The ancestors of the two aspen diverged into P. davidiana and P. tremula species
