Development and characterization of 24 chloroplast microsatellite markers for two species of Eranthis (Ranunculaceae).

Chloroplast microsatellites for two Korean endemic species, Eranthis byunsanensis and E. pungdoensis (Ranunculaceae), were isolated to address the questions of their distributional patterns and evolutionary relationships, using next-generation sequencing. Twenty-four polymorphic chloroplast microsatellite markers for these two species were developed, and then characterized in 65 individuals (55 individuals of E. byunsanensis and 10 individuals of E. pungdoensis). The number of alleles per locus ranged from 2 to 9; the average number of alleles across all the loci scored 4.792. The unbiased diversity per locus ranged from 0.089 to 0.880; the unbiased diversity averaged over all the loci was 0.646. The developed markers were successfully amplified for three congeneric species, E. stellata, E. pinnatifida, and E. longistipitata. The markers developed in this study can provide a valuable and important tool for understanding genetic variations, population structures, evolutionary histories and phylogeography of E. byunsanensis, E. pungdoensis, and related species.
