A rotting bacterium was isolated from decayed root of ginseng (Panax ginseng Meyer), cultured purely, and its pathogenicity was confirmed by reinoculation test. The strain causing ginseng root rot was identified as Pseudomonas fluoresens biotype II. The strain was somewhat different from P.marginalis and P.talaasii, considering the number of flagella, pathotype and ability of indole production. The strain did not exhibit pathogenicity to other plants tested, such as red kidney bean(Phasolus vulgaris L.), soy bean (Glycine max Merr.), cucumber (Cucumis sativus L.) lettuce (Lactuca sativa L.) and cowpea bean (Vigna sinensis Savi.).

Objects : Glycine max Merr. (black bean), Triticum aestivum L. (wheat) and Oryza sativa L. (rice bran) have been widely used for treatment of relaxion of smooth muscle, gastrointestinal hemorrhage and alopecia in Korean Traditional Medicine. In this research, we examined the effect of the extracts, obtained from EtOH extracts of 3 kinds of traditional plants, on hair growing activity of the DP6 and C3H10T1 cell and physical properties. Materials and Methods : On the basis of previous studies, three traditional plants were selected and we extracted them with ethanol. We evaluated their hairy dermal papillar cell proliferation activity and mouse mesenchymal stem cell in vitro model. Also, 3 herbal extracts were added to the normal shampoo formulation in ranges of 0.1% and we validated tensile properties and physical changes using aged hair. In this research, we compared the tensile strength, shine and color appearance between the hair (general formulation) and the hair after applying shampoo with natural extracts. To analyze the luster and color image, we use the SAMBA hardware and software made by Bossa Nova Technologies. Results : In the comparative test for tensile characteristic between the hair treated general formulation(control) and the hair applying special formulation including 3 kinds of extracts, tensile distance and energy of the latter are larger than control on average. The shine and color appearance were also increased after using shampoo including natural extracts(shine : 10.9%, color appearance: 24.12%). We observed the enhancement of hair growth activity in the DP6 and C3H10T1 cell. Especially black bean extracts had the most powerful effect in the dermal papillar cell proliferation. Conclusion : These experiments suggest that extracts of Glycine max Merr. (black bean), Triticum aestivum L. (wheat) and Oryza sativa L. (rice bran) stimulate the hair growth activity and can improve physical activities of aged hair. Shampoo product, which contains 3 kinds of natural extracts, would be used for the treatment for aged hair.

The soybean [Glycine max (L.) Merr.] is one of the most important crop resources worldwide as food and forage. It is also important and valuable that to hold crop resources to have high genetic diversities. Recently, a core collection has been constructed in many plants to preserve the genetic resources of various plants. A core collection is small population to represent the genetic diversity of the total collection, and is of strategic importance as they allow the use of a small part of a germplasm collection that is representative of the total collection. Here, we developed the core collection consisting of 816 accessions by using approximately 180,000 (180K) single nucleotide polymorphisms (SNPs) developed in previous study. In addition, we performed genetic diversity and population structure analysis to construct the core collection from entire 4,392 collections. there were excluded sample call rates less than 93% and duplicated samples more than 99.9% according to genotype analysis using 180K SNPs from entire collections. Furthermore, we were also excluded natural hybrid resources which Glycine max and Glycine soja are mixed in half through population structure analysis. As a result, we are constructed the core collection of genetic diversity that reflects 99% of the entire collections, including 430 cultivated soybeans (Glycine max) and 386 wild soybeans (Glycine soja). The core collection developed in this study should be to provide useful materials for both soybean breeding programs and genome-wide association studies.

Photosynthetic variation in field grown soybean [Glycine max (L.) Merr. cv Hodgson78］ was studied in relation to leaf anatomical variation. Variations in mesophyll morphology were accentuated by manipulating source and sink size. At R3 stage, two treatments were started: one was thinning and continu-ous debranching(6. 5 plants rather than 26 plants per m of row and remaining plants were debranched weekly), and the other was continuous partial depodding (allowing only one pod to develop at each mainstem node). Gas exchange characteristics, mesophyll cell volume and surface area per unit leaf surface, and microclimatic parameters were measured on the intact terminal leaflet at the 10th node. Observations were made 5 times with 3 to 4 day intervals starting R4 stage. Two models were used to compute leaf photosynthetic rates: one considered no effect of mesophyll morphology on photosynthesis, and the other considered potential effects of variations in mesophyll cell volume and surface area on diffusion and biochemical processes. Seventy nine percent of total photosynthetic variations observed in the experiment was explained by the latter, while 69% of the same variations was explained by the former model. By incorporating the mesophyll morphology concept, the predictability was improved by 14.6% in the field condition. Additional Index Words: photosynthesis model, leaf anatomy, Glycine max (L.) Merr., mesophyll surface area, mesophyll cell volume.

Soybean (Glycine max (L.) Merr.) is a high-protein oilseed crop, cultivated worldwide. Soybean seeds are abundant in various secondary metabolites with physiologically active. Mature seeds of 25 soybean cultivars with various morphological and physiological characteristics analyzed for secondary metabolites, such as carotenoid, isoflavone, and soyasaponin. These secondary metabolites showed various content by genotype in 25 cultivars. Total carotenoid content ranged from 1.23 to 33.78 mg/g and three cultivars, such as IT177645, PI90763 and IT234975 with black seed coat showed high levels of total carotenoid. Total isoflavones content ranged from 20.28 to 276.35 mg/100g and were detected high levels in Savoy, PI90763 and KLG16001. In addition, total soyasaponins content ranged from 33.12 to 246 mg/100g and were detected high levels in PI90763, PI86490 and IT234975. The PI90763 was showed abundant content in all of the carotenoid, isoflavones and soyasaponins. These results could be valuable information for the development of new soybean cultivars and regulation of secondary metabolites biosynthesis in soybean.

The major mycotoxins were detected from wheat(Triticum aestivum L.), soybean(Glycine max Merr.) and com(Zea mays L.), infected postharvest phathogens, Penicillium, Aspergillus and Fusarium. Analyses of the major mycotoxins were conducted using HPLC analysis. Detected Penicillium mycotoxins of infected cereals were brefeldin A with amount ranged from 3.1 to 1240 ppm, citreoviridin with amount ranged from 40 to 80 ppm, griseofulvin with amount ranged from 3.6 to 26.0 ppm, citrinin with amount ranged from 0.3 to 4.0 ppm and patulin with amount ranged from 420 to 3800 ppm. Aspergillus toxins of infected postharvest wheat, soybean and corn were ochratoxin A with amount of 730 ppm, 12.4 ppm and 310 ppm, respectively.

Chloroplasts isolated from tobacco (Nicotiana tabacum L. cv. Virginia 115) leaves have been transferred into protoplasts of soybean (Glycine max Merr. cv. Jangyeop) suspension-cultured cells with the help of polyethylene glycol (PEG). The increased yield in protoplasts of chloroplast uptake was depended upon the concentration of both PEG 4,000 and PEG 6,000. The highest yield(36%) occurred at 50% of both PEG, and the yield was decreased above this concentration. The rate of uptake with the incubation time was highest at one hour, then decreased. The process of the chloroplast uptake into the protoplasts was similar with that of a protoplast fusion, except forming invagination during uptake.
