Inferring complex evolutionary history of the closely related East Asian wild roses in Rosa sect. Synstylae (Rosaceae) based on genomic evidence from conserved orthologs.

We have unravelled the complex evolutionary history of East Asian Rosa sect. Synstylae, including recent species divergences, ILS, and genetic introgression. Coupled with the geographical and ecological complexity of East Asia, ILS and genetic introgression may have contributed to the rapid diversification of East Asian Synstylae species by permitting adaptation to diverse environments.
