Background : Angelica species are representative medicinal plants and it has been used in traditional medicinal methods, especially, in the traditional Asian medicine. The Angelica species used in conventional medicine varies by country according to specific regulations, i.e. A. gigas Nakai in Korea, A. sinensis Diels in China, and A. acutiloba Kitagawa in Japan. Because of the similarity between the names among Angelica, they can be confused in the market.
Methods and Results : In this study, twenty-four chloroplast insertion or deletion (cpInDel) markers were developed from chloroplast DNA of A. gigas Nakai and tested for the classification of Angelica species. Primer sets were designed from flanking sequences of the discovered InDel loci from chloroplast DNA of A. gigas Nakai using CLC Main Workbench with the following parameters : primer length = 18 - 26 bp (Opt. 23 bp); GC% = 50 - 70% (Opt. 60%); Ta = 55 - 62℃ (Opt. 58℃); product size range = 120 - 300 bp. Polymorphism and genotype analysis of 13 Angelica species were performed using the developed cpInDel markers.
Conclusion : The 24 cpInDel markers developed in this study could be used for genetic diversity analysis and classification of Angelica species.
