Genetic diversity of the traditional Chinese medicinal plant Ypsilandra thibetica (Melanthiaceae): Applications for conservation

► Population number declining and habitat shrinking in Ypsilandra thibetica were steadily continuous during the last two decades. ► Twelve SSR marks were developed to determine the genetic diversity and genetic structure. ► The results suggested that the environment factors might restrict gene flow among populations. ► Ypsilandra thibetica should be a high priority for conservation managers.
