Genetic variation and differentiation among populations of Euphorbia ebracteolata (Euphorbiaceae) in Korea

다국어 초록 (Multilingual Abstract)

Using starch gel electrophoresis, ten isozyme loci were examined in nine populations of Euphorbia ebracteolata in Korea. Populations of E. ebracteolata tend to have higher within-population levels of genetic variation (A = 2.2, P = 61.1, He = 0.165) along with low levels of genetic differentiation (FST = 0.075) compared to previously reported Euphorbia species. The relatively high genetic variation in E. ebracteolata may be due to its long-lived regional distribution and to the outcrossed nature of the species. Low levels of genetic differentiation and the absence of unique alleles in E. ebracteolata populations suggest that Korean populations diverged recently. This study does not support the recognition of var. coreana and for. magna as separate taxa, and suggests that they should be combined with E. ebracteolata.
