Microsatellite markers for the critically endangered elm species Ulmus gaussenii (Ulmaceae)

Genes Genet Syst. 2016 Jul 20;91(1):11-4. doi: 10.1266/ggs.15-00053. Epub 2016 Apr 1.


The Anhui elm Ulmus gaussenii is listed as a critically endangered species by the International Union for Conservation of Nature and is endemic to China, where its only population is restricted to Langya Mountain in Chuzhou, Anhui Province. To better understand the population genetics of U. gaussenii, we developed 12 microsatellite markers using an improved technique. The 12 markers were polymorphic, with the number of alleles per locus ranging from two to nine. Observed and expected heterozygosities ranged from 0.021 to 0.750 and 0.225 to 0.744, respectively. The inbreeding coefficient ranged from -0.157 to 0.960. Significant linkage disequilibrium was detected for two pairs of loci, and significant deviations from Hardy-Weinberg equilibrium were found in nine loci. These microsatellite markers will contribute to the studies of population genetics in U. gaussenii, which in turn will contribute to species conservation and protection.
