Genetic diversity of Eusideroxylon zwageri (Teijsm. & Binn.) in Indonesia revealed by nuclear microsatellite markers

抄録

Conservation status of Eusideroxylon zwageri (Teijsm. & Binn.) in Indonesia has being vulnerable to endangered since 1990s due to overexploitation and its unique biological characteristics. In order to design conservation and breeding strategies, we assessed genetic diversity within and among 9 natural populations in Sumatera and Kalimantan Island using 11 nSSR markers.
Value of genetic diversity was in moderate level (mean H_E=0.641), albeit coefficient inbreeding was significant in several populations. PCO analysis divided the populations into 3 clusters i.e. Musi Rawas (Sumatera), West Kalimantan, Jambi (Sumatera) and others Kalimantan populations. Structure analysis showed optimum value for K was 3 that supported the PCO analysis. However, using these nSSR markers, gene migration process among provinces, even among Islands is still unknown, thus it will be determined by cpDNA markers in the future study.
