Out of the Qinghai-Tibet Plateau: evidence for the origin and dispersal of Eurasian temperate plants from a phylogeographic study of Hippophae rhamnoides (Elaeagnaceae)

Popis výsledku v původním jazyce

Numerous temperate plants now distributed across Eurasia are hypothesized to have originated and migrated from the Qinghai-Tibet Plateau (QTP) and adjacent regions. However, this hypothesis has never been tested through a phylogeographic analysis of a widely distributed species. Here, we use Hippophae rhamnoides as a model to test this hypothesis. We collected 635 individuals from 63 populations of the nine subspecies of H. rhamnoides. We recovered five major clades in phylogenetic trees constructed from cpDNA and ITS sequence variation. Most sampled individuals of six subspecies that are distributed in northern China, central Asia and Asia Minor - Europe, respectively, comprised monophyletic clades nested within those found in the QTP. Our phylogeographic analyses supported an out-of-QTP? hypothesis for H. rhamnoides followed by allopatric divergence, hybridization and introgression. These findings highlight importance of the QTP as a center of origin for many temperate plants.
