Evolutionary history of an alpine shrub Hippophae tibetana (Elaeagnaceae): allopatric divergence and regional expansion

Popis výsledku v původním jazyce

Increasing evidence suggests that geological or climatic events in the past promoted allopatric speciation of alpine plants in the Qinghai-Tibetan Plateau and adjacent region. However, few studies have been undertaken to examine whether such allopatric divergences also occurred within a morphologically uniform species. In the present study, we report the evolutionary history of an alpine shrub species, Hippophae tibetana, based on examining chloroplast DNA (cpDNA) and nuclear ribosomal internal transcribed spacer (ITS) DNA variations. We sequenced two cpDNA fragments (trnL-F and trnS-G) and the nuclear ITS region in 183 individuals collected from 21 natural populations. These findings, when taken together, suggested that this species had experienced long allopatric divergence and recent regional range expansions in response to orogenic processes and the climate changes. The evolutionary history of this shrub species highlights importance of geographical isolations to the intraspecific
