Aridification of Asia and the closure of the Turgai Strait in the Late Oligocene promoted the dispersal of Cardueae from the Mediterranean to East China. Subsequent uplift of the Qinghai-Tibet Plateau as well as changes in Asian monsoon systems resulted in an East Asian-Tethyan disjunction between Atractylodes and Carlina + Atractylis + Thevenotia. In addition, Late Miocene to Quaternary climates and sea level fluctuations played major roles in the diversification of Atractylodes. Through this study of different taxonomic levels using genomic data, we have revealed an overlooked dispersal route between the Mediterranean and far East Asia (Japan/Korea) via Central Asia and East China.
