Genetic diversity and conservation of Korean endemic species Maianthemum bicolor (Nakai) Cubey (Asparagaceae s.l.).

Maianthemum bicolor (≡Smilacina bicolor Nakai) was first described by T. Nakai from the material collected at Banyabong, Mt. Jiri, Korea, in 1913. M. bicolor has been designated as an endangered species by Korean government due to its limited distirbution and population reduction in Korea peninsular. Currently, M. bicolor is found along the mountain ridges or slopes over 1400 m in the southern part and over 1200 m in northern part of South Korea. Its morphological and reproductive system indicates its close relationship with two Japanese dioecious species, M. yesoense (Franch. & Sav.) La Frankie and M. viridiflorum (Nakai) H. Li. To investigate its genetic diversity and provide strategies for conservation, we have applied AFLP method for 192 individuals from seven populations in Korea. The results suggested strong correlation between the genetic diversity and the geographic distance of the populations analyzed. Also, the seven populations investigated were divided into two genetic/geographic groups, due to low elevations of mountain ranges in the middle part of South Korea, which probably worked as physical barrier. With the increasing influence of global warming, this cold-adapted Korean endemic species will suffer reduction in distibution range and population size. Thus, further environmental and population viability assessment, and conservation plans are required for the species.
