Genetic variation of the rare Astilboides tabularis and relatively widespread Rodgersia podophylla (Saxifragaceae) in Korea.
Genetic variation from 13 Korean populations of A. tabularis and R. podophylla was compared using isozyme markers. A. tabularis is rare endemic species distributed limited numbers of populations in Korea and Northeastern China, while R. podophylla is relatively widespread in China, Japan and Korea. Comparing species with similar life history the results of isozyme electrophoretic analyses represented the high genetic variation and low levels of genetic differentiation in above two species. Especially, the high genetic diversity founded in rare endemic A. tabularis (A = 2.0, P= 75.0 and Ho=0.428) is unusual and could be explained by the stable populations survived in refugia during the last glaciation in the Korean peninsula. Comparing to the FST value of the A. tabularis (FST = 0.108), R. podophylla (FST = 0.056) has relatively low FST values, and it is explained by the possible seed dispersal by wind in this species. Comparing to other populations within A. tabularis, Myeonsan population shows the highest genetic variation and covers all of the available alleles within the species. Thus, the priority of species conservation should be set on Myeonsan population of A. tabularis.
