참당귀 엽록체 InDel 마커를 이용한 Angelica 속 식물의 분류
길진수,이재복,구성철,김호방,이이 한국약용작물학회 2018 한국약용작물학술대회 발표집 Vol.2018 No.05
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.

약용 식물 자원은 천연 화장품 소재, 제약 산업 그리고 인간의 건강을 위한 기능성 식품의 개발로 확대 된 이후 중요한 자산이 되고 있다. 그러나 세계적으로 약용 식물의 명칭을 각각 다르게 표기하고 있으며 계통 발생학적 기원이 명확하지 않다는 단점을 지니고 있다. 이 때문에 소비자들은 매우 큰 혼란을 겪고 있으며 특히 형태학적으로 유사한 식물의 말린 뿌리로 유통될 때에는 전문가들도 그들의 기원을 구별하기가 매우 어렵다. 이러한 이유때문에 이처럼 광범위하고 다양한 작물의 기원을 식별하기 위해 분자표지 기법을 적용하여 활용되고 있다. 이 리뷰에서 본 연구자들은 Angelica종의 분화에 관한 적합한 '기원정립'을 위한 현재의 연구 성과들을 정리했다. 결론적으로 Angelica종의 식별을 위해 개발된 분자적 연구에 대해 설명하고 약용작물의 유전체 정보를 활용하여 그들의 기원정립 및 판별에 대해 논의할 것이다. Medicinal plants resources are becoming important assets since their usages have been expanded to the development of functional foods for human health, natural cosmetics, and pharmaceutical industries. However, names are different from each country and their phylogenetic origins are not clear. These lead consumers to be confused. In particular, when they are morphologically similar and distributed as dried roots, it is extremely difficult to differentiate their origins even by specialists. Recently, molecular markers have been extensively applied to identify the origin of many crops. In this review, we tried to overview the current research achievements for the development of suitable 'origin identification' regarding to the differentiation of Angelica species. Furthermore, more advanced techniques including amplification genome based marker analyses are also discussed for their practical applications in the authentication of particular medicinal plant in Angelica species.

Background: Panax ginseng C. A. Meyer is wood-cultivated ginseng (WCG) in Korea which depends on an artificial forest growth method. To produce this type of ginseng, various P. ginseng cultivars can be used. To obtain a WCG similar to wild ginseng (WG), this method is usually performed in a mountain using seeds or seedlings of cultivated ginseng (CG) and WG. Recently, the WCG industry is suffering a problem in that Panax notoginseng (Burk.) F. H. Chen or Panax quinquefolium L. are being sold as WCG Korean market; These morphological similarities have created confusion among customers. Methods and Results: WCG samples were collected from five areas in Korea. After polymerase chain reaction (PCR) amplification using the primer pair labeled with fluorescence dye (FAM, NED, PET, or VIC), fragment analysis were performed. PCR products were separated by capillary electrophoresis with an ABI 3730 DNA analyzer. From the results, WCG cultivated in Korea showed very diverse genetic background. Conclusions: In this study, we tried to develop a method to discriminate between WCG, P. notoginseng or P. quinquefolium using simple sequence repeat (SSR) markers. Furthermore, we analyzed the genetic diversity of WCG collected from five cultivation areas in Korea.

RAPD 분자표지를 이용한 Codonopsis 속 식물의 유전적 다양성 분석
길진수, 장유지, 안연주, 이이 忠北大學校 農業科學硏究所 2020 農業科學硏究 Vol.36 No.1
Codonopsis is a genus containing 42 species of perennial herbaceous plant in the family Campanulaceae. They are widely distributed in Asia, mainly in Korea, China, Japan, Afghanistan and the Himalayas. Studies of Codonopsis species have been conducted primarily on C. lanceolata and C. pilosula in Korea and China. However, research on these species is insufficient now. In this study, a total of 60 Operon’s primers were tested and 18 RAPD (random amplified polymorphic DNA) molecular markers were selected to identify genetic variations in the Codonopsis species. Genetic variation was calculated for 10 Codonopsis species using the 18 RAPD molecular markers, and the relationship and genetic diversity of these species were analyzed. These studies would be helpful for various genetic studies and species discrimination of genus Codonopsis.
