  • Scopolia parviflora of the family Solanaceae is an endemic species of Korea and a traditional Korean medicinal plant. The plastid genome was sequenced by next-generation sequencing (NGS) method. The characterized cp genome is 156,193 bp in size; the large single-copy (LSC) region is 86,364 bp, the inverted repeat (IR) is 25,905 bp, and the small single copy (SSC) region is 18,019 bp. The overall GC content of the plastid genome amounts to 37.61%. The cp genome contains 113 genes and 21 introns, including 80 proteincoding genes, four RNA genes, 30 tRNA genes, 20 group II introns, and one group I intron. A phylogenetic analysis showed that Scopolia parviflora was closely related to Hyoscyamus niger.

  • Internal transcribed spacer (ITS) sequences of nuclear ribosomal DNA were determined for 14 individuals representing eight taxa from Scopolia s. str. and related genera, Anisodus and Atropanthe. We found that the ITS sequences of Korean endemic species, S. parviflora, are significantly different from its allied species, S. japonica. This is contradictory to traditional taxonomic treatments in which those species are regarded as conspecific. S. parviflora exhibited closer relationship to S. carniolica, which is disjunctly distributed in Europe. In spite of substantially high sequence divergence between S. japonica and S. parvlflora/S. carniolica clade, morphological resemblance is evident among the species. Morphological stasis concept (retardation of morphological differentiation or evolution of similar characters among the disjuncts in a similar ecological habitat) was referred to understand this rather unusual evolutionary feature. S. lutescens, another Korean endemic species, shared almost identical ITS sequences with S. parviflora. Lack of diagnostic character distinguishing the taxa suggests that they are conspecific. Anisodus carniolicoides, which was originally described in Scopolia, was grouped with A. luridus and A. tanguticus. The monophyletic Anisodus formed a sister group relationship with a monotypic genus Atropanthe.

  • Total RNAs were isolated from cultured roots of Scopolia parviflora, $poly(A)^+$ RNA was obtained through the mRNA purification, cDNA library of Hnh6h was constructed. Recombinant baculoviruses in Spodoptera frugiperda (Sf) cells were constructed by use of the transfer vector pBacPAK, which has the AcNPV sequence under the polyhedrin promoter. The expression vector carrying Hnh6h gene was transferred to S. parviflora and obtained transgenic hairy root lines. Our results confirmed the over expression of the H6H protein was used by anti-pBacPAK about cDNAs of S. parviflora. This study will served for production of tropane alkaloids by metabolic engineering.

  • Transformed hairy roots of Scopolia parviflora, producing tropane alkaloids and native to Korea, were obtained following infection of rhizome segments with Agrobacterium rhizogenes A4. Each root tip induced from inoculum sites excised and cultured in MS agar or liquid medium. About seventy of hairy root clones were established. Among them, several fast growing hairy root clones were examined for alkaliod content. Two dimensional TLC analysis showed that the tropane alkaloid pattern of hairy root was more complicated than that in the rhizome of mother plant. On the other hand, some hairy root clones did not produce scopolamine and hyoscyamine. In HPLC analysis, some hairy root clones yield higher levels of scopolamine and hyoscyamine than those of mother plant rhizome which used for infection. Scopolamine and hyoscyamine were identified by comparison of their retention times and of their spectra data with those of authentic compounds.

  • Scopolia parviflora Nakai, a rare and endangered species, is the sole plant producing tropane alkaloids (TA) among the Korean native species. In order to enhance TA productivity the SP72 root line was selected by screening 100 of root line, and the optimal culture media for root growth and TA production were investigated with the SP72 roots. Based on the several media, SH and 2B5 medium were determined as growth medium and White and NN medium as production medium. Among the four combinations of two-stage culture, 2BN (2B5 as growth medium plus NN as production medium) showed more enhanced root growth and TA production as compared with production media of White and NN medium and growth media of SH and 2B5 medium, respectively. However, bubble column bioreactor (BCB) cultures applying two-stage culture did not reveal the effective results despite of the each successful operation of two-stage culture in conical flasks and BCB cultures.

  • ScopoIamine and hyoscyamine which belong to tropane alkaloids are the pharmaceutically valuable anticholinergic drugs. In order to increase the productivities, the effects of elicitation were investigated during hairy root cultures of Scopolia. parviflora. Biotic elicitors originated from 3 fungi and 1 yeast were prepared as homogenate and supernatant and added to 3-week-old cultures. Both of homogenate and supernatant of Candida albicans elicitors increased the scopolamine production. The production of hyoscyamine was enhanced by homogenate of Fusarium solani and supernatant of C. albicans. Most of the other fungal elicitors were also improved on the tropane alkaloid production compared to non-treatment. Among the elicitors tested, C. albicans was proved the optimal biotic elicitor on tropane alkaloids production. These results will be served mass production of tropane alkaloids by large-scale production.

  • The hyoscyamine 6${\beta}$-hydroxylase (h6h) gene was introduced into the genome of Scopolia parviflora through the Agrobacterium rhizogenes binary vector system. The enzyme was expressed ally and tissue specific selectively in roots, resulting in five transgenic hairy root lines. The presence of the h6h gene in kanamycin-resistant hairy roots and its overexpression were confirmed by polymerase chain reaction (PCR), Northern blotting, and Western blotting, respectively. In the transgenic hairy root lines which constitutively expressed the H6H enzyme, hyoscyamine and scopolamine accumulated in high concentration. Among the transgenic hairy root lines that expressed the H6H enzyme, only two were more productive. The levels of tropane alkaloids in transgenic hairy root varied greatly: The best transgenic line (#5) contained 8.12 mg of scopolamine per g dry weight, which produced the compound three times more than wild-type root. These results suggest a possibility of improving the yield of tropane alkaloids in hairy root lines by genetic and metabolic engineering.

  • The morphological characteristics of the Korean Scopolia japonica Maxim., commonly known as 'Mi-chi-gwang-i-pul' in Korean, were re-evaluated in comparison with results from previous research, while the distribution map was formulated according to existing flora and voucher specimens. The result of the re-evaluation has shown that there are some distinctive discrepancies compared to the previous reports of some characteristics such as the color of the basal stem, numbers of lateral veins, apex shape of calyx and corolla including the color of corolla. The Korean Scopolia japonica Maxim is found throughout Korea except Jeju-do province. The intra-specific species such as S. parviflora (Dunn.) Nakai, S. lutescens Y.N. Lee and S. kwangdokensis Y.N. Lee were treated as synonyms of S. japonica Maxim. in this research.
