Abstract

Juniperus tibetica Kom. is a tetraploid endemic tree species of the southern Tibetan Plateau. For this species ten microsatellite markers were developed using next generation sequencing. To characterize these loci a sample of 14 juniper individuals from seven populations covering large parts of the species’ distribution range was analyzed. All loci were polymorphic, ranging from two to 15 alleles per locus. Expected heterozygosity was estimated using the program TETRASAT, and ranged from 0.20 to 0.90 across loci. These markers will be used in ongoing population genetic studies to evaluate the potential genetic depauperation of the highly fragmented forest remains on the southern Tibetan Plateau and to propose strategies for conservation management.
