Development and characterization of microsatellite markers for Hibiscus glaber Matsum. ex Nakai, an endemic tree species of the oceanic Bonin Islands, Japan.

Polymorphic microsatellite markers were developed for Hibiscus glaber, an endemic tree of the Bonin Islands. Eighty-seven of the 208 sequences from an enriched library were unique and containing microsatellites. Ten loci were proved to be highly polymorphic among 78 individuals from the Nishi-jima Island. Total exclusionary powers for the first and the second parents were 99.989% and 99.999%, respectively. Nine loci also amplified single fragment from genomic DNA of H. tiliaceus, a related and widespread congener. Our markers can be reliably used for the estimation of current gene flow within/among populations of the two woody Hibiscus species.
