摘要 Tetrastigma hemsleyanum (Vitaceae) is an endangered medicinal plant endemic to China. Because of its widely known efficacy for treating many health problems, wild resources of this species are currently undergoing a rapid decline. Few studies have been conducted examining the population genetics or development of microsatellite loci for this plant. In this study, 14 microsatellite loci were isolated and characterized for T. hemsleyanum using a double-suppression PCR method. Polymorphisms were tested with a total of 50 individuals from 2 natural populations. The number of alleles per locus ranged from 3-9, with an average of 7 alleles per locus. The observed and expected heterozygosity per locus ranged from 0-1 and from 0.068-0.803, respectively. The polymorphism information content value varied from 0.215-0.760. These loci may facilitate further genetic studies of populations of T. hemsleyanum and provide guidance for their conservation.
