Abstract
Here,we infer the historical biogeography and evolutionary diversification of the genus Lilium.For this purpose,we used the complete plastomes of 64 currently accepted species in the genus Lilium(14 plastomes were newly sequenced)to recover the phylogenetic backbone of the genus and a time-calibrated phylogenetic framework to estimate biogeographical history scenarios and evolutionary diversification rates of Lilium.Our results suggest that ancient climatic changes and geological tectonic activities jointly shaped the distribution range and drove evolutionary radiation of Lilium,including the Middle Miocene Climate Optimum(MMCO),the late Miocene global cooling,as well as the successive uplift of the Qinghai-Tibet Plateau(QTP)and the strengthening of the monsoon climate in East Asia during the late Miocene and the Pliocene.This case study suggests that the unique geological and cli-matic events in the Neogene of East Asia,in particular the uplift of QTP and the enhancement of monsoonal climate,may have played an essential role in formation of uneven distribution of plant di-versity in the Northern Hemisphere.
