Table_2_Origin and evolutionary history of Populus (Salicaceae): Further insights based on time divergence and biogeographic analysis.xlsx
Introduction Populus (Salicaceae) species harbour rich biodiversity and are widely distributed throughout the Northern Hemisphere. However, the origin and biogeography of Populus remain poorly understood. Methods We infer the divergence times and the historical biogeography of the genus Populus thro...
