The genetic variation of four endangered plant species endemic to Korea and implications for conservation.
The genetic diversity and divergence of four endangered plant species endemic to Korea were studied using the allozyme and ISSR markers. The spring ephemeral mymecochorous perennial Corydalis filistipes (Fumariaceae) and perennial Bupleurum latissimum (Umbelliferae) are endemic to Ullung island (area, 75.4km2), 141 km east of the Korea peninsula and were investigated with allozyme markers. The perennial, Primula farinosa subsp. modesta var. koreana and annual, Impatiens hypophylla var. koreana were surveyed with ISSR markers, and are rarely distributed in the southern mountaintop and the southern coast and islands, respectively. The genetic diversity(He) of four populations for C. filistipes and three populations for B. latissimum were a moderate level as 0.167and 0.14 of average, respectively. Shannon's index(I) of P. farinosa subsp. modesta var. koreana with four populations and I. hypophylla var. koreana with three populations showed some high levels as 0.32 and 0.39, respectively. Most genetic variations for two plant species in Ullung island are founded within rather than among populations (GST =0.06 and 0.13, respectively), whereas the degree of genetic differentiation (GST) among populations in both P. farinosa subsp. modesta var. koreana and I. hypophylla var. koreana distributed in southern regions of mainland was high as 0.46 and 0.28, respectively. Based on these results, the strategies for conservation and the program for management are proposed for four endangered endemic plants in Korea.
