Population genetic analysis of an endangered Korean fir (Abies koreana, Pinaceae) and conservation implication.

The Abies koreana E. H. Wilson, known as one of the charismas trees, is an endemic and rare species from Korea, whose distribution is limited to the high elevation of mountains in the Jejudo and the southern region of Korean peninsula. This species is considered to be endangered by IUCN because of repeated population reduction. We have developed 22 novel polymorphic microsatellite markers and the characteristics of these loci based on 454 GS-FLX Titanium sequencing data and were determined in A. koreana and A. nephrolepis, the most closely related species. Population genetic analysis of 265 individuals of wild and cultivated A. koreana and 146 individuals of A. nephrolepis was performed using these novel microsatellite markers. Abies koreana was divided into two metapopulations. The Halla population was isolated from rest of local populations in Korean peninsula, showing lowest genetic diversity even though the biggest population of this species. Among local populations in Korean peninsula, the Jiri population represented the highest genetic population and asymmetrically higher gene flow to other local populations, implying a critical role to maintain genetic diversity of other smaller local populations. All wild populations have undergone recent genetic bottleneck and a certain level of gene flow from A. nephrolepis exists. The afforest area of A. koreana in Jiri Mountain and Moodeung Mountain shows mixed genetic composition from Halla and Korean peninsula metapopulation. Also, all Europe and US commercial breds and Korean commercial individuals were identified from Halla metapopulation. Based on this result, we suggest that this two metapopulation should be considered as separate conservation management units and more deliberated afforestation plan is needed. Also, Jiri population might be investigated as a good genetic resource for further breed improvement of A. koreana.
