DNA Barcoding Study of Korean Euphorbiaceae Juss.

The Euphorbiaceae family consists of more than 8,000 species that are vastly distributed in tropical and temperate regions. Many species in Euphorbiaceae has been well known as its economical implications related with pharmaceutical, cosmetical and toxicological aspects as well as their taxonomic difficulties. In this study, we investigated three DNA regions (matK, rbcL, and nrITS) for DNA barcodes for identifying species within Korean Euphorbiaceae. Of 86 accessions collected from 24 species in 10 diverse genera, matK, rbcL, and nrITS successfully identified >90% and 100% of them at the species and genus levels, respectively. In nrITS region, all the species examined were differentiated except for four species in two subsection (subsect. Galarrhoei and subsect. Euesulae). Within the genus Euphorbia, Korean endemic E. fauriei did not recognized, and nested within E. pekinensis accessions in neighbor-joining tree based on rbcL and matK combined data. Thus, it supports the E. fauriei as an infra-species status such as E. pekinensis var. fauriei rather than independent species of E. pekinensis.
