Abstract

Development and characterization of microsatellite loci in Excentrodendron hsienmu (Chun & How) H.T. Chang & R.H. Miau

Microsatellite markers were isolated using dual-suppression-PCR for the endangered species Excentrodendron hsienmu (Tiliaceae) to evaluate the genetic diversity and population structure of this species. A total of 11 polymorphic microsatellite loci were characterized in E. hsienmu. The number of alleles per locus ranged from 2 to 9, with an average of 5.27. The expected heterozygosity value ranged from 0.053 to 0.780, with an average of 0.568 and the observed heterozygosity value ranged from 0 to 0.595, with an average of 0.268. The polymorphic information content value ranged from 0.051 to 0.740, with an average of 0.521. These newlydesigned markers will be of great potential significance and profound influence in future research related to the genetic diversity, population structure, and patterns of gene flow of this species, which will contribute to the implementation of conservation and management strategies for this species.
