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.

Scopolia s. str.(미치광이풀속) 및 그 근연속인 Anisodus, Atropanthe 등을 대표하는 8 분류군으로부터 얻은 14개체를 대상으로 핵 ribosome DNA의 ITS 염기서열 결정을 실시하였다. 그 결과 한반도 고유종인 S. parviflora(미치광이풀)은 ITS 전체 길이와 염기서열 변이에 있어서 근연종인 S. japonica와 매우 큰 차이가 있음이 밝혀졌다. 이와 같은 결과는 두 종을 동일시했던 대부분의 분류학적 견해와 배치되는 것이다. 한편, S. parviflora는 유럽에 격리분포하는 종인 S. carniolica와 더 가까운 계통유연관계를 나타냈다. S. japonica가 S. parviflora 및 S. carniolica와 높은 유전적 차이를 나타내는 것과는 대조적으로 매우 높은 형태적 유사성을 보이는 것은 이들이 오랜 격리기간에도 불구하고 유사한 생육환경에 처함으로 인해 형태진화가 지연되었거나 비슷한 형질을 갖는 방향으로 진화가 일어났을 것이라는 형태정체(morphological stasis) 개념으로 이해되었다. 다른 한반도 고유종인 S. lutescens(노랑미치광이풀)은 S. parviflora와 ITS 염기서열이 거의 동일하였고 계통수 상에서도 두 종에 속하는 개체들이 전혀 구분되지 않는 것으로 밝혀졌다. 자연개체군 내에서 이들 두 종을 구분하는 주요 식별형질들의 유용성도 결여되어 S. lutescens는 S. parviflora의 품종 혹은 단순한 개체 변이로 이해되었다. 한편, Scopolia속으로 최초 기재되었다가 화분의 형질에 의해 Anisodus속으로 이전되었던 A. carniolicoides는 A. luridus 및 A. tanguticus와 단계통군을 형성하였으며 Anisodus는 단형속인 Atropanthe와 자매군 관계를 형성하였다.

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.

미치광이풀의 모상근 뱌양에 의해 의학적으로 중요한 물질인 scopolamine과 hyoscyamine 생산을 증진시키기 위해 3종의 곰팡이와 1종의 효모 유래의 생물학적 elicitor를 supernatant와 homogenate의 형태로 처리하였다. Elicitor 중 Candida albicans는 supernatant와 homogenate 모두 scopolamine 생산성을 증가시켰다. Fusarium solani의 homogenate와 C. albicans의 supernatant 처리로 hyoscyamine 함량이 증가되었다. 그러나 나머지 fungus strain도 대조구에 비해 tropane alkaloids의 생산을 다소 증가시켰다. 본 연구에서는 C. albicans가 tropane alkaloids 생산에 적합한 elicitor임으로 구명되었다. 본 연구 결과는 미치광이풀 모상근 대량배양에 의한 tropane alklaoids 대량생산에 기여할 것이다.

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.
