Identification and characterization of 12 microsatellite Loci in Cnidium dubium (Apiaceae) using Next-generation Sequencing

Abstract

Premise of the study: We present a set of 12 polymorphic nuclear microsatellite loci, identified for the first time within the herbaceous plant species Cnidium dubium (Schkuhr) Thell. using next-generation sequencing. Methods and Results: To characterize these loci, 40 plants were analyzed genetically. The number of alleles ranged from 2 to 23, with an average of 8.3 alleles per locus. Mean observed and expected heterozygosities ranged from 0.25 to 0.95 and 0.30 to 0.94, respectively. Conclusions: All 12 nuclear microsatellite loci showed scorable and polymorphic fragments after polymerase chain reaction. The new marker set can be used for future studies of genetic diversity and differentiation as well as estimation of gene flow and spatial genetic structures. © 2011 Botanical Society of America.
