본 실험은 초화류인 코레우스의 삽목시 삽수의 발근율을 높이기 위하여 배양액과 NAA 및 IBA처리 효과를 조사하였다. 모래삽목보다는 배양액을 이용한 것이 발근소요일이나 생육면에서 월등히 효과적이었다. 특히 배양액 농도는 일본 원시표준액보다는 표준액의 1/4 배양액 농도에서 재배한 것이 가장 발근이 빨리 되었으므로 삽목초기에는 낮은 양액농도가 경제적일 것으로 보인다. 생장조절제의 농도별로는 NAA나 IBA 0.01mg/$\ell$처리가 효과적이었으며 IBA처리보다는 NAA처리시의 발근소요일이 더 짧았다. 또한 NAA 및 IBA을 처리한 수돗물을 사웅하여 삽수의 발근을 유도할 경우 NAA와 IBA를 삽수에 침지처리한 후 수돗물에 재배하는 것보다 발근에 효과적이었으며, 무엽지삽보다는 유엽지삽이 효과적이었다. 또한 배양액이나 생장조절제를 단용처리한 것보다 배양액과 생장조절물질의 혼용처리가 발근소요일이 단축되었고 생육상태가 양호하였다.

섬오갈피 부정근의 생장과 생리활성물질 생산에 적합한 MS 배지 내 오옥신(IBA, NAA, IAA)과 사이토키닌(BA, kinetin, TDZ)의 종류와 농도를 구명하고자 250mL 삼각플라스크를 이용하여 5주간 액체 진탕 배양하였다. IBA $5mg{\cdot}L^{-1}$ 처리구에서 생체중과 건물중이 가장 높았으며, 부정근 내 총 페놀과 플라보노이드 함량 역시 NAA나 IAA처리구에 비해 높았다. 오옥신과 사이토키닌의 혼용처리에 따른 부정근의 생장은 IBA $5mg{\cdot}L^{-1}$와 TDZ $0.1mg{\cdot}L^{-1}$와의 혼용 처리구가 IBA 단용 처리구에 비해 생체중과 건물중이 각각 1.4배와 1.6배 증가하여 가장 높은 생장량과 생리활성물질 함량을 나타내었다. 이에 비해 BA와 kinetin과의 혼용 처리는 IBA 단용 처리와 비교해 부정근의 생장과 생리활성물질 생산에 크게 영향을 주지 않았다. 본 실험을 통하여 MS 배지 내 오옥신과 사이토키닌을 IBA $5mg{\cdot}L^{-1}$와 TDZ $0.1mg{\cdot}L^{-1}$로 혼용 처리 할 경우 섬오갈피 부정근의 생장량과 생리활성물질 함량을 크게 증가시킬 수 있음을 확인하였다.

This study aimed to investigate the effect of growth regulators on the formation of the organ in the in vitro propagation of diploid and tetraploid Codonopsis lanceolata, and gain the basic data for in vitro propagation of superior C. lanceolata. In the case of diploid C. lanceolata, the highestshoot formation (3.0) was observed at 0.5 mg·L^-1 addition medium with low IBA concentration. The shoot formation of tetraploid C. lanceolata was suppressed by addition of IBA. In the addition of lAA, the shoot formation of diploid C. lanceolata was slightly higher at 1.0 mg·-L^-1 addition medium than that of control group, whereas tetraploid C. lanceolata showed the highest number (5.4) from control group. In the case of NAA, the shoot formation of diploid and tetra C. lanceolata tended to decrease at higher concentration. In terms of BA addition, the shoot formation of diploid C. lanceolata was increased by the addition of BA, whereaswhile the growth of shoot was decreased by the addition of BA. In the case of tetraploid C. lanceolata, shoot was found to be formed by the addition of low concentration of BA, and the growth of shoot was inhibited with the higher addition concentration of BA. With the addition of kinetin, the shoot formation of diploid C. lanceolata was slightly higher than that of control group, and the formation of adventitious root was highest (5.3) in the control group. In the case of tetraploid C. lanceolata, the shoot formation was similar in all treatment groups, but the formation and growth of adventitious root were significantly lower than that of diploid C. lanceolata. In the case of TDZ addition, the shoot formation of diploid C. lanceolata showed the pronounced results at 5.0 mg·L^-1 addition medium, and the growth of shoot was inhibited by the addition of TDZ. The formation of adventitious root was 5.3 and 4.9 in the control group and 0.1 mg·L^-1 addition medium respectively. The formation of the shoot of tetraploid C. lanceolata showed better results with the higher concentration of TDZ, and the growth was better with the lower concentration of TDZ. The formation and growth of adventitious root were significantly slower than that of diploid C. lanceolata.

Background: Panax ginseng Meyer is a traditional medicinal plant famous for its strong therapeutic effects and serves as an important herbal medicine. To understand and manipulate genes involved in secondary metabolic pathways including ginsenosides, transcriptome profiling of P. ginseng is essential. Methods: RNA-seq analysis of adventitious roots of two P. ginseng cultivars, Chunpoong (CP) and Cheongsun (CS), was performed using the Illumina HiSeq platform. After transcripts were assembled, expression profiling was performed. Results: Assemblies were generated from ~85 million and ~77 million high-quality reads from CP and CS cultivars, respectively. A total of 35,527 and 27,716 transcripts were obtained from the CP and CS assemblies, respectively. Annotation of the transcriptomes showed that approximately 90% of the transcripts had significant matches in public databases.We identified several candidate genes involved in ginsenoside biosynthesis. In addition, a large number of transcripts (17%) with different gene ontology designations were uniquely detected in adventitious roots compared to normal ginseng roots. Conclusion: This study will provide a comprehensive insight into the transcriptome of ginseng adventitious roots, and a way for successful transcriptome analysis and profiling of resource plants with less genomic information. The transcriptome profiling data generated in this study are available in our newly created adventitious root transcriptome database (http://im-crop.snu.ac.kr/transdb/index.php) for public use.

This experiment was conducted to investigate the effect of growth medium in pots composed of upland soil(S), rice straw manure(M), carbonated rice hull(CRH), and their mixture on growth of tobacco cv. NC 82. The growth of shoot and root was vigorous in order of medium S+M+CRH>M>CRH>S. In M+S medium, root growth in the part of manure was superior to upland soil. But root growth of upland soil part in M+S plot was more vigorous than that in upland soil only. It is possibly due to be influenced by manure in M+S plot. Total length and weight of root, number of roots, and especially for development of adventitious root were closely related to shoot growth. Roots grown in upland soil part was brownish gray in color, while the roots in manure part was milky white. The milky white colored roots had longer life than others. It was concluded that root zone environments derived from several media in pots closely related to shoot growth and disease tolerance of tobacco plant.

The study was carried out to clarify reasonable production of healthy seedling, optimal Pot depth, and appropriate transplanting time, which can be deduced from understanding of seedling quality. Seedling quality results from growth of root and shoot, morphology and distribution of root system under influence of Pot depth during seedling growing period. Stem height, shoot dry weight, leaf area and leaf number were increased in proportion to depth of pots. Growth of shoot and root during seedling growing period showed the most dramatic development between 20th and 25th day after temporary planting. Root number increased as pot depth decrease and total root length and dry weight increased as pot depth increase. In 5cm pot, relative multiplication rate was higher and mean extension rate was lower than other depth of Pot. The limitation of pot volume in which rhizosphere was located enhance the development of roots of second and third order. At 20th days after temporary Planting root distribution was relatively uniform in length and development of adventitious root on stem base was poor as Pot depth decreased.

Background: To obtain useful cosmetic resources, this study aimed to determine the non-saponin fatty acid and inhibitory activities of collagenase and elastase by treatment of Saccharomyces cerevisiae in supercritical fluid extracted oil of the adventitious root culture of wild mountain ginseng. Methods and Results: We performed supercritical fluid extraction at various conditions such as pressure, temperature, time, and use of co-solvents, unlike the n-hexane extraction for the adventitious roots culture of wild mountain ginseng. The non-saponin-fatty acid obtained from the oil of the adventitious roots culture was incresed by treatment with S. cerevisiae. The supercritical fluid extraction was conducted using gas chromatography. Non-saponin-fatty acid content, in the oil of adventitious roots culture of wild mountain ginseng treated with S. cerevisiae for 2 days were three times higher than that in the control. In addition, the oil of the adventitious roots culture treated with S. cerevisiae was investigated for the anti-wrinkle effect by using collagenase and elastase. The oil of adventitious roots culture treated with S. cerevisiae exhibited higher collagenase and elastase inhibitory activities than those in the control. Conclusions: Supercritical fluid extracted oil of the adventitious roots culture of wild mountain ginseng treated with S. cerevisiae was found to have decreased ratio of saturated fatty acids and incresed ratio and content of unsaturated fatty acids increased. Furthermore, it showed anti-wrinkle effects in vitro.
