Premise of the study: Polymorphic microsatellite markers of Zanthoxylum schinifolium (Rutaceae), a promising medicinal plant with effective antibacterial, anticancer, and anti-inflammatory compounds, were developed and evaluated for further genetic studies based on genetic variation among individuals or populations.
Methods and results: Following the selective hybridization method, microsatellite-enrichment libraries were constructed. Using these libraries, we obtained 15 polymorphic and three monomorphic microsatellite markers for Z. schinifolium. The number of alleles observed in each of the 15 polymorphic loci ranged from two to eight, and the observed and expected heterozygosities ranged from 0.070 to 0.677 and from 0.093 to 0.688, respectively. Eleven of these developed markers were successfully amplified for Z. piperitum, a related species.
Conclusions: These microsatellite markers can be valuable tools for further genetic studies of Z. schinifolium, such as genetic resource conservation for maintaining breeding material and individual identification for breeding program improvement and variety management.
