Phylogeography of Iris loczyi (Iridaceae) in Qinghai-Tibet Plateau revealed by chloroplast DNA and microsatellite markers.

ABSTRACT: Quaternary climate oscillations and complex topography have tremendous effects on current distribution and genetic structure of species, and hence the Qinghai-Tibet Plateau (QTP), the largest plateau in the world, has become a hotspot for many phylogeographic studies. However, little is known about the phylogeographic pattern of herbaceous plants in QTP. Here, we investigate the genetic diversity, population structure and historical dynamics of Iris loczyi, using five chloroplast DNA (cpDNA) fragments and seven microsatellite markers. A total of 15 populations, and 149 individuals were sampled throughout the QTP. High genetic diversity was detected both in cpDNA (H _d = 0.820) and SSR (H _o = 0.689, H _e = 0.699).
