  • Angelica is a widely used medicinal and perennial plant. Information on the genetic diversity of Angelica populations is essential for their conservation and germ plasmic utilization. Although Angelica is an important medicinal plant species registered in South Korea, no molecular markers are currently available to distinguish it from other similar species from different countries. This developed single nucleotide polymorphism (SNP) markers derived from nuclear ribosomal DNA internal transcribed spacer regions genomic sequences to identify distinct Korean-specific Angelica species via amplification refractory mutation system (ARMS)-PCR curve analyses. We performed molecular authentication of different kinds of Korean-specific Angelica species such as A. gigas Nakai and A. gigas Jiri using DNA sequences in the ITS intergenic region. The SNP markers developed in this study are useful for rapidly identifying specific Angelica species from different countr.

  • Objectives : Angelica Gigantis Radix is prescribed as the root of different Angelica species on the pharmacopoeia in Korea, Japan and China. Chemical components and their biological activities were also different according to their species. A study for the development of simple method to compare Angelica roots was needed. In order to classify them, the methods such as DNA sequencing analysis and taste sensor were applied to three Angelica species like Angelica gigas, Angelica acutiloba and Angelica sinensis. Methods : PCR amplification of intergenic transcribed spacer (ITS) region was performed using ITS1 and ITS4 primer from nine Angelica roots, and then nucleotide sequence was determined. Taste pattern of samples were measured using the taste-sensing system SA402B equipped with a sensing unit, which consists of artificial lipid membrane sensor probes of anionic bitterness, astringency, saltiness, umami, and cationic bitterness (C00, AE1, CT0, AAE, and AN0, respectively). Results : As a result of comparing the similarity of the ITS region sequences, A. sinensis was discriminated from the others (A. gigas and A. acutiloba). Equally this genetic result, A. gigas and A. acutiloba showed similar taste pattern as compared to A. sinensis. Sourness, bitterness, aftertaste of bitterness, astringency, and aftertaste of astringency of A. sinensis were significantly high as compared with A. gigas and A. acutiloba. In contrast, richness was significantly low. Conclusions : These taste pattern can be used as a way of comparison of Angelica species and this technic could be applied to establish a taste pattern marker for standardization of herbs in various purposes.

  • The taxonomy of the umbelliferous species Angelica amurensis and its allies was reviewed on the basis of molecular phylogenies derived from sequences of nuclear ribosomal DNA internal transcribed spacer (ITS) regions. Strict consensus of six minimal length 119-step trees derived from equally weighted maximum parsimony analysis of combined nuclear rDNA ITS1 and ITS2 sequences from 29 accessions of Angelica and outgroups indicated that Angelica purpuraefolia, known to be endemic to Korea, is the same species as A. amurensis. Comparisons of sequence pairs across both spacer regions revealed identity or 1-2 bp differences between A. purpuraefolia and A. amurensis. These results indicated that the two taxa are not distinguished taxonomically. Also, nuclear rDNA ITS regions are discussed as potential barcoding loci for identifying Korean Angelica.

  • During a disease survey in October 2019, leaf spot symptoms with a yellow halo were observed on Korean angelica (Anglica gigas) plants grown in fields in Pyeongchang, Gangwon Province, Korea. Incidence of diseased leaves of the plants in the investigated fields ranged from 10% to 60%. Morphological and cultural characteristics of two single-spore isolates from the leaf lesions indicated that they belonged to the genus Didymella. Molecular phylogenetic analyses using combined sequences of LSU, ITS, TUB2, and RPB2 regions showed distinct clustering of the isolates from other Didymella species. In addition, the morphological and cultural characteristics of the isolates were somewhat different from those of closely related Didymella spp. Therefore, the novelty of the isolates was proved based on the investigations. Pathogenicity of the novel Didymella species isolates was confirmed on leaves of Korean angelica plants via artificial inoculation. This study reveals that Didymella gigantis sp. nov. causes leaf spot in Korean angelica.

  • A comparative study on 'Dang-gui' and 'Kang-whal' the two species of Angelica growing in Korea was carried out about the morphology and cytology. The somatic chromosome number of Cham dang-gui, Ill dang-gui, Badi-namul was found to be 2N=22. The somatic chromosome number of Kang-whal was found to be 2N=110, that of Chili kang-whal to be 2N=44, that of Mul kang-whal to be 2N=22. Stoma of species of Dang-gui were same in size. Those of Chili kang-whal and Kang-whal were strikingly larger than the other. Chili kang-whal and Kang-whal were verified to be polyploid in the genus Angelica.

  • During disease surveys of Angelica acutiloba plants in Korea, leaf spot symptoms were observed in a field in Andong in July 2019, and stem rot symptoms in vinyl greenhouses in Yangpyeong in April 2020. Incidence of leaf spot and stem rot of the plants ranged from 10 to 20% and 5 to 30%, respectively. Morphological and cultural characteristics of fungal isolates from the leaf spot and stem rot symptoms fitted into those of the genus Phoma. Molecular phylogenetic analyses of two single-spore isolates from the symptoms using concatenated sequences of LSU, ITS, TUB2, and RPB2 genes authenticated an independent cluster from other Didymella (anamorph: Phoma) species. Moreover, the isolates showed different morphological and cultural characteristics in comparison to closely related Didymella species. These discoveries confirmed the novelty of the isolates. Pathogenicity of the novel Didymella species isolates was substantiated on leaves and stems of A. acutiloba through artificial inoculation. Thus, this study reveals that Didymella acutilobae sp. nov. causes leaf spot and stem rot in Angelica acutiloba.

  • Analysis of random amplified polymorphic DNAs(RAPDs) and internal morphological features were performed using three species of medicinal plants in the genus of Angelica(A. gigas Nakai, A. sinensis(Oliv.) Diels., A. acutiloba Kitagawa) to distinguish between these three species. Fifty decarmer oligonucleotide primers were screened for the RAPDs of the herbal plant species. Five primers generated distinct RAPD markers specific to the species of Angelica, In analysis of the degree of similarity, A. sinensis(Oliv.) Diels is more closely related to A. acutiloba Kitagawa than to A. gigas Nakai. Furthermore, we proved the usefulness of RAPD analysis for the discrimination of the species using dry roots and commercial plant materials. In internal morphology of three species, A. sinensis(Oliv.) Diels seemed to be more specialized in systemic than A. acutiloba Kitagawa and A. gigas Nakai
