Premise Of The Study:
Ephedragerardiana (Ephedraceae), occurring in the Himalayan ranges, is an important plant species used in Tibetan medicine. Due to the lack of molecular markers to characterize genetic diversity, knowledge for conservation and uses of E. gerardiana resources is limited; we therefore developed microsatellite markers for use in this species.
Methods And Results:
Using Illumina MiSeq sequencing technology, we developed 29 polymorphic microsatellite loci suitable for E. gerardiana, of which 15 loci also showed polymorphisms in two related Ephedra species, E. saxatilis and E. monosperma. The average number of effective alleles per locus ranged from two to six. The observed and expected heterozygosity ranged from 0.23 to 0.83 and 0.44 to 0.86, respectively, in E. gerardiana populations.
Conclusions:
The developed 29 microsatellite markers are effective for the study of genetic structure and genetic diversity of E. gerardiana, and 15 of these markers are suitable for related Ephedra species.
