초록

한국산 물통이(Pilea)속 식물의 분자계통학적 연구를 통해서 총 1속 5분류군으로 정리하였다. 물통이속은 모두 1년생 초본으로, 그늘지고 습기가 있는 지역에서 서식하며, 여름에 꽃이 피고, 가을에 열매를 맺는다. nrDNA의 ITS regions과 cpDNA의 psbA-trnH regions의 DNA 염기서열의 분석 결과, 산물통이, 물통이는 분계조를 각각 형성하였다. 하지만 제주 산방산의 제주큰물통이는 내륙지역의 지리산에서 자생하는 제주큰물통이와 같은 분계조를 형성하지 못하고 큰물통이, 모시물통이와 섞여 분계조를 형성하였다. ITS1, 4 regions에서만 DNA 염기서열이 분석된 지리산의 제주큰물통이 역시 완전히 다른 분계조를 형성하였다. 단순히 지리적인 차이로 인해 형성되었다고 보기에 무리가 있을 것으로 생각되어지며, 후에 좀 더 많은 연구가 이루어져야 할 것으로 생각되어진다.

A study of the genus Pilea in Korea including five taxa was carried out using molecular phylogenetic methods. The majority of members of the genus Pilea in Korea are annual herbs, and they live in moist habitats, flowering in summer and fruiting in autumn. The results of a phylogenetic analysis using nrDNA and cpDNA supported the recognition of P. japonica, P. peploides, and P. taquetii. Pilea taquetii from Mt. Sanbangsan in Jeju was nested within P. hamaoi and P. mongolica clade instead of the P. taquetii clade, with P. taquetii from Mt. Jirisan also separated from the P. taquetii clade. This indicates that the separation is not geographical isolation, but is instead related to taxonomic problems. Therefore, further study of the P. taquetii group is necessary.
