This study was conducted to estimate the control thresholds (CTs) at different larval densities of Oides decempunctatus Billberg (Coleoptera: Chrysomelidae) of Campbell early in the vineyard and investigated life cycle. Each stage of O. decempunctatus was sampled 18 times from May to September in 2010~2012. The seasonal occurrence of O. decempunctatus showed the highest peak in mid-late June and mid-late August. Overwintered O. decempunctatus's eggs were hatched from late May to early June. Larva period was from late May to mid July and adults appeared in mid July. The percentage of leaf damage (Y) of Campbell early inoculated by different densities of O. decempunctatus (X, no. of larvae/fruiting mother branch) for six weeks was estimated by Y= 0.498X+2.041 (R2=0.988) during vegetation period. The decreasing rate of soluble solid (Y) after grape harvest of Campbell early damaged by different densities of O. decempunctatus (X) was estimated by Y= - 0.046X+15.3 (R2=0.8543). Based of the relationships between the densities of O. decempunctatus larvae and the index of reducing soluble solid of Campbell early, the number of larvae (2nd to 3rd instar) which decreased less than 15°Bx loss of soluble solid was determined as the injury level of 7/fruiting mother branch.

A full genomic DNA microarray technique was employed to investigate the effects of Dongchunghacho on aortal and hepatic gene expression in apolipoprotein E knockout mice fed a high-fat/high-cholesterol diet. Male 8- week - old ApoE-/- mice were randomly divided into two groups, control(high cholesterol group; HC) and supplementation of Dongchunghacho (SD). All of the mice were fed a high-fet/high cholesterol diet with or without Dongchunghacho supplemented by 1% for 6 weeks. At first, lipid profile of the Dongchunghacho was measured by biochemical analysis. No differences were observed in serum triglyceride and total cholesterol levels between the two groups. Antigenotoxic effect of the Dongchunghacho was measured by the single cell gel electrophoresis assay (Comet assay) and quantified as % fluorescence in tail. Dongchunghacho supplementation decreased significantly leukocytic DNA damage and also there was a tendency of reduction in hepatic DNA damage in Dongchunghacho group compared with the control group. In up regulated genes in liver and aorta of the mice, genes with 0 to 2- fold difference in expression level between the two group (HD and SD) was very much more in liver than in aorta, on the contrary, those with 2-fold to 16-flod difference increased greatly rather in aorta than in liver. Also, almost the same results were observed in down regulated genes in liver and aorta between the two groups. These results suggested that supplementation of Dongchunghacho might be helpful in preventing leukocytic DNA damage induced by high fat diet, and has a more crucial roles in aortal gene expression.

Background : Licorice has been used as a source of medicine and a food material in East-Asia. Recently, demand for licorice increased in market due to a growing interest in health. Thus we conducted breeding research to solve the problems associated with domestically cultivated licorice such as low productivity and low glycyrrhizin content. Methods and Results : We crossed European licorice (G. glabra L.; female parent) and Chinese licorice (G. uralensis Fisch; male parent) in the greenhouse in May 2007. In September 2007, crossed and germinated seeds were retrieved and sown in the greenhouse. In June 2008, stolons were separated from the F1 licorice seedlings and cultivated, resulting in 32 clonal lines of interspecific hybrids. Among them we selected good lines and then conducted the replicated yield trials (RYT) in 2012-2013 and local adaptability test (LAT) in 2014-2015. The results, GLYES9 showed that was elect of stem, oblong of leaf shape, red-brown of root color. Glycyrrhizin conten of GLYES9 (3.0%) was higher than G. uralensis (1.9%) at four regions from 2014 to 2015. GLYES9 was less than 10% in the desease of brown spot (G. uralensis was more than 30%). The root yield of GLYES9 was 4.31 ton per hectare, which was increased 193% compared with a check variety of G. uralensis. Therfore, we named GLYES9 as new cultivar ‘Dagam’. Conclusion : Depending on the above results, we have developed a new licorice cultivar ‘Dagam’ by the medicinal crop breeding team of National Institute of Horticulture and Herbal Science, RDA, in 2015. It showed brown spot disease resistant, high-glycyrrhizn content and high-yielding than colleted Glycyrrhiza spp.

Background : Cucuma longa L., in the family Zingiberaceae, is distributed in tropical and/or sub-tropical regions mainly in India and China. This species is commonly called tumeric, powder is used as medicinal herbs and/or flavor enhancer. It has been cultivated in southern region mainly Jindo. However, it might be possible to extend cultivation region due to rise in average temperature. In order to select superior lines, agronomic characteristics is commonly used. Because this is not the ultimate solution, the DNA marker approach has benefited the modern plant breeding. Therefore an easy approach by using one kind of primer have been developed from random amplification of polymorphic DNA sequences (RAPD) to discriminate effectively between different cultivars of Cucuma species Methods and Results : DNAs were extracted from the harvested roots of Cucuma sp. using DNeasy plant Mini kit (Qiagen, Hilen, Germany). These plants cultivated from GARES (Hamyang) and used for PCR amplification. The relative concentration of the extracted DNA was estimated Nano Drop ND-1000 (NanoDrop Technologies, Wklmington, De, USA) and final DNA concentration was adjusted to 5.5 ng/㎕. In this study 9 primer pairs were tested on 8 Cucuma sp. These primers showed polymorphism in Cucuma sp. The cluster dendogram showed that the similarity coefficients ranged from 0.68 to 0.87, CUR02 turned out to be CUR11, and CUR16 is similar to CUR17. Conclusion : These finding could be used for further research on cultivar development by using molecular breeding techniques and for conservation of the genetic diversity of Cucuma species. These data on polymorphism difference based on RAPD will be give us invaluable breeding information by selection of superior lines.
