Objectives: This study was carried out to discriminate origin and molecular marker of oriental medicine Cnidii Rhizoma be circulated between Korea and China, which is difficult to discriminate from morphological distinction because of a fragmental materials of roots. Methods: Materials were collected randomly from a medicinal herb markets in Korea and China and be analyzed with ITS (internal transcribed spacer) regions of nuclear ribosomal DNA (nrDNA). Results: As a results, ITS regions of nrDNA was shown to be identify as three molecular markers. Cnidii Rhizoma was made up syster group of the genus Ligusticum L. and divided into three groups with Tou-chun-gung, IL-chun-gung and China-chun-gung. Conclusions: From the analysis of ITS regions of nrDNA, we presumed that it is the same origin of Cnidii Rhizoma from Korea and China because of phylogenetic tree consisted of sister groups with the genus Ligusticum than the genus Cnidium.

독도의 미기록 식물 참빗살나무 핵과 엽록체 DNA의 분자마커 이용

The present scientific scenario shows that, the long-distance dispersal of any species plays a major role in population as well as the flow of individual between populations. However, newly recorded plant at Dokdo was confirmed by using morphological and molecular markers of nrDNA and cpDNA. This scientific study has identified the plant species was as a Euonymus hamiltonianus Wall. (Celastraceae). And after careful studies, the laboratory results shows that the distribution of tree species at Dokdo as an Oceanic Island is a meaningful thing because of the inflow of plant in adverse condition of environment such as a shallow soil layers and steep terrain. So it is necessary to continuous monitor for the inflow of non-indigenous plant into Dokdo.

본 연구는 독도의 식물상과 식생을 모니터링하여 독도생태계의 보존과 관리를 위한 기초자료를 제공하고자 수행하였다. 독도의 식물상은 29과 48속 49종 1아종 3변종 총 53종류로 기록되었다. 이 중 특산식물은 섬기린초와 섬초롱꽃 2종류이고, 귀화식물은 갓, 방가지똥, 큰이삭풀, 콩다닥냉이, 흰명아주, 둥근잎나팔꽃 등 6종류로 확인되었다. 특히, 둥근잎나팔꽃은 본 조사에서 처음으로 보고되었다. 식생형은 주로 해국-땅채송화, 해국-갯제비쑥, 왕호장근-도깨비쇠고비, 돌피, 물피군락 등으로 구분되었다. 독도에 분포하는 식물에 대한 오동정의 논란이 지속되고 있으며, 이를 위하여 분류군별 전문가의 조사가 필요하고, 고유식생을 유지하기 위하여 귀화식물 및 재배식물의 모니터링과 관리가 필요하다. This study was carried out to describe the basic materials of the flora and vegetation for the conservation and management of the Dokdo ecosystem. The vegetation types were investigated by physionomy. 53 taxa of vascular plants were found, including 29 families, 48 genera, 49 species, 1subspecies, and 3 varieties. Among the investigated 53 taxa, it was recorded as follows: 2 Korean endemic plants included Sedum kamtschaticum var. takesimense M.Park and Campanula takesimana Nakai and 6 naturalized plants included Brassica juncea (L.) Czern., Sonchus oleraceus L., Bromus catharticus Vahl, Lepidium virginicumL., Chenopodium album L., and Ipomoea purpurea Roth. In particular, common morning glory (Ipomoea purpurea Roth) was reported for the first time in this survey of Dokdo. Based on physionomy, the main plant communities of Dokdo Island were Aster spathulifolius-Sedum oryzifolium community, Aster spathulifolius-Artemisia Japonica subsp. littoricola community, Fallopia sachalinensis-Cyrtomium falcatum community, Echinochloa crusgalli community, Echinochloa crusgalli var. oryzicola community. The debates have been continuing about a mis-identification of plants. To avoid this debate and manage naturalized and cultivated plants, taxonomist surveys and continual monitoring for the Island are required.
