Background : Root diseases caused by Cylindrocarpon destructans and Fusarium solani decrease the yield and quality of ginseng. Cylindrocarpon root rot is a major disease caused by replanting failure in ginseng garden. Methods and Results : Solarization was done in the infested soil of the greenhouse for summer season (from July 24 to Autumn 31, 2014) after putting green manure (Sudan grass) and calcium cyanamide (CC) into the soil. Mycelium and conidia of C. destructans died at 4 0℃ after 15 hours, and 45℃ after 5 h, but it did not die at 35℃ after 15 h. Those of C. destructans died after keeping it for 2 hours daily at 40℃ for 9 days, and 45℃ for 8 days, but did not die at 38℃ for 9 days. Maximum soil temperature was 55.4℃ in 5 cm depth, 48.7℃ in 10 cm, 44.7℃ in 15 cm, 42.5℃ in 20 cm, and 31.9℃ in 30 cm by putting green manure into the soil and solarization. Reduction of sudan grass increased electrical conductivity (EC), organic matter, P2O5, K, and Mg, while decreased pH, NO3-N, and Na. Addition of calcium cyanamide and urea gave a negative effect on the growth of ginseng because EC and NO3-N were increased excessively than the optimal range. Solarization using green manure mixed with CC was the most effective in decreasing soil-borne pathogens of 2-year-old ginseng. But the root disease that occurred between single treatment of sudan grass and the treatment mixed with calcium cyanamide showed not a significant different. Addition of calcium cyanamide showed the decrease of root weight because leaves were dead early by a excessive increase of EC and NO3-N. Conclusion: Soil disinfection using green manure and solarization in greenhouse was effective in inhibiting root rot, however, it did not completely kill the soil-borne pathogens.

Background : Angelica gigas is a monocarpic biennial or short lived perennial plant. A. gigas, also called Dang Gui or Korean Angelica, is a major medicinal herb used in Asian countries such as Korea, Japan and China. In Korea, we are using the roots of A. gigas, but, they are using Angelica sinensis in China and Angelica acutiloba in Japan to obtain many active constituents. The biggest problem in the using of A. gigas would be the confusion with A. acutiloba or A. sinensis. These three plants can't be distinguished by appearance. And the constituent ratios of the three plants are different. This confusion can cause an accident or the pharmaceutical effects do not meet the expectations. In this study, we developed chloroplast SSR markers that can distinguish A. gigas, A. acutiloba and A. sinensis. Methods and Results : We collected A. gigas, A. acutiloba and A. sinensis. and extrated DNA using CTAB method. The DNA was diluted to 10 ng/㎕ and kept -20℃. We designed the primer sets using CLC Main Workbench based on chloroplast DNA SSR region of A. gigas. PCR were performed on the three angelica plant samples (in 5 repeat). Conclusion : We made five primer sets from five SSR regions of A. gigas cpDNA. All of the primer sets amplified the amplicon effectively. Two of the 5 primer sets had polymorphism. We can distinguish A. gigas, A. acutiloba, and A. sinensis using the 2 primer sets

Background : Codonopsis lanceolata is used as a natural medicine or vegetables. It originates in East Asia such as Korea, Japan and China. C. lanceolata roots contain various chemical compounds including saponins like Panax ginseng. Although C. lanceolata are cultivated in different regions of South Korea, no variety has been developed. Therefore, it is necessary to develop discriminating methods such as molecular markers in C. lanceolata species. Methods and Results : To find simple sequence repeat (SSR) markers, we sequenced C. lanceolata genomic DNA using Illumina HiSeq 2000 System. A total of 250,455 putative SSR loci were obtained, and 26,334 non-redundant primers were designed to amplify these SSRs. Di-nucleotied repeats were the most abundant SSR reapeats, accounting for 89.53% (23,578) of primer designed SSRs. Tri-nucleotide, tetra-nucleotide and penta-nucleotide accounted for 8.44% (2,223), 1.3%, (348) 0.2% (55), respectively. Tri-, tetra-, and penta-nucleotide (total of 2,626 SSRs) were investigated in silico to identify polymorphism between individuals. Consequently, 573 SSRs showed polymorphism. Forty genomic SSR markers were tested in 16 C. lanceolata plants for determination of PCR amplification and polymorphism. From these primers, 27 (67.5%) amplified products and the average polymorphism information content (PIC) value was 0.52. Conclusion : We development 27 SSR markers from C. lanceolata using NGS, and it could be used for breeding of new varieties in the future.

Background : Osteoclasts as multinucleated cells originate from hematopoietic monocyte/ macrophage precursor cell, shows the bone absorption through the commitment, differentiation, fusion, and bone resorption stages by regulation of M-CSF and RANKL. It has been reported a significant negative correlation between the increase of oxidative stress and the bone density, and when RANKL reaction to the osteoclasts precursor cells is mainly generated ROS is due to increased activity of NADPH oxidase1 (NOX1), and these ROS act as a factor which promotes osteoclasts differentiation. Thus, RANKL signaling process is important that excessive osteoclast formation and differentiation inhibited through the regulation of each step. Methods and Results : F3570 ethanol extract showed relatively high activity at in-vitro antioxidant activity. F3570 water extract inhibited ROS generation in RAW 264.7 cells stimulated with H2O2 and RANKL, even at low concentrations. The inhibitory effect of osteoclast differentiation on F3570 water extract was confirmed that shown through NF-κB pathway, MAPK pathway including ERK and JNK. F3570 ethanol extract is considered to be regulated by the p38 MAPK and the other signaling pathway. Also, F3570 both water and ethanol extract were significantly reduced gene expression such as TRAP, calcitonin receptors and integrin β3 of RANKL-induced mature osteoclast in the bone resorption stage. Conclusion : Through this study, F3570 extract revealed an outstanding inhibitory effect and signaling mechanisms in osteoclast differentiation induced by RANKL. These results suggest that F3570 is bone diseases associated with aging or osteoporosis caused by menopause in an aging society is expected to be a superior candidate for the treatment or the prevention

Background : Korean Red Ginseng has been reported to have various anti-virus, anti-tumor, anti-inflammation and immune-regulating activity. However, Korean Red Ginseng Crude Saponin (KRGCS) effect on Pulmonary inflammation has been insufficient research. We have investigated the effect of KRGCS on pulmonary inflammation in mouse model. Methods and Results : Pulmonary inflammation induced by cigarette smoke condensates (CSC) and lipopolysaccharide (LPS) in BALB/c mice. 100uL (ratio 1:1) of CSC (4mg/mL) and LPS (100ug/mL) solution instilled with intratracheal injection once per a week for 3 weeks in mice. KRGCS was also administered orally a dose of 10mg/kg and 25mg/kg for 3 weeks. KRGCS treatment groups decreased the number of inflammatory total cells in lung tissues and bronchoalveolar lavage fluid (BALF) and the number of neutrophils in BALF dropped more than negative control groups. Additionally, KRGCS reduced the absolute number of CD4+ and CD8+ cells in BALF, and the number of CD11b+ Gr-1+cells in the lung and BALF. Furthermore, we found that KRGCS declined significantly the level of the cytokine chemokine (C-X-C motif)-1 (CXCL-1), Macrophage inflammatory protein-2 (MIP-2), and tumor necrosis factor alpha (TNF-α) in BALF. Conclusion : These results that KRGCS has an inhibitory effects on pulmonary inflammation such as COPD, may be a candidate of effective herbal pharmaceuticals for the cure of lung diseases.

Background : Panax ginseng C.A.Meyer is a perennial herb and its growth potential keep relatively high at least for the early 3 years old. If the transplanted ginseng roots of 2 or 3 years old grow well, a period of cultivation and the disease management cost could be reduced for the production of 6 years old ginseng roots. Methods and Results : The rooting and growth of a transplanted ginseng root could be affected by the age of a transplant. Therefore, the experiments were conducted to examine the influences of the age factor on the rooting and growth of transplanted ginseng roots. The ginseng roots with different plant ages in growth years (1, 2, and 3 years old), used in this study, were obtained by raising in a seedling production field near the Punggi Ginseng Experiment Station. The transplants were continuously grown under the same conditions after transplanting. The number of lateral or branched roots at the root-growing period after transplanting was basically higher in originally older plant ages compared to younger plants: the numbers of secondary and tertiary branched roots of the 1 year-old transplants were 8, 12, respectably; 2 years old: 12, 20; 3 years old: 12, 28. Those did not show any difference in both overground and underground growing, in compared to conventional cultivations with roots of a year old. The plants grew well without anthracnose, spotting disease, and high temperature injury. Conclusion : The conventional cultivation period of above 5 or 6 years for the raw material of red ginseng might be shorten and also the cost of disease control could be decreased, by transplanting of 2 or 3 years old roots raised at a seedling nursing field.

Background : Yam absorbs nutrition and water through water absorptive root generated from head of rhizome. Round-shaped yam (RSY, Dioscorea opposita) and tropical round-shaped yam (TRSY, Dioscorea alata)are more sensitive to drought because of shorter head of rhizome and shallower root compared to long yam or short yam. This study was conducted to elucidate the effect of irrigation on RSY and TRSY yam at 205 in Institute of Bioresources Research, GBARES. Methods and Results : Tuber of RSY and TRSY were cut as 40 g, and dust-coating sterilized with lime. Seedlings were grown in heating wire installed seed bed from 25. March to 16. April. Experimental field were fertilized 2,000 kg compost, 34 kg N2, 28 kg P2O5, and 28 kg K2O. All amount of compost and P2O5 treated as basal fertilizer. N2 and K2O treated 14 and 10 kg of basal fertilizer, and 20 and 18 kg of additional fertilizer, respectively. Tillage, installation of drop-watering tapes, and covering black PE film with 60×25 cm spacing holes on 120 cm row were conducted. 20 L per m2 was irrigated 7 days interval except rainy day from middle of May to late of September. RSY had high emergence rate in early stage due to irrigation, while TRSY had no difference. Irrigation was not effective on total number of tuber but number of marketable tuber (over 200 g). Marketable tuber yield of RSY according to irrigation was increased 89% as 1,147 kg per 10 a. And tuber with irrigation was 73 g heavier. Tuber yield and marketable tuber yield of TRSY as affected by irrigation were respectively 2,611 and 1,715 kg per 10 a compared to control, 1,462 and 428 kg. And irrigated tuber was 66 g heavier. Conclusion : TRSY had more effective on irrigation than RSY. Both of yam had significant increased marketable tuber yield due to irrigation. Therefore RSY and TRSY are necessarily irrigated because of those absorptive characteristics, short head of tuber and shallow root.
