  • 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.

  • Plastid transformation was attempted with soybean [Glycine max (L.) Merr.] leaves and photoautotrophic and embryogenic cultures by particle bombardment using the transforming vector pZVII that carries the coding sequences for both subunits of Chlamydomonas reinhardtii Rubisco and a spectinomycin resistance gene (aadA). Spectinomycin resistant calli were selected from the bombarded leaves but the transgene was not present, indicating that the resistance was due to mutations. The Chlamydomonas rbcL and rbcS genes were shown to be site-specifically integrated into the plastid genome of the embryogenic cells with a very low transformation efficiency. None of the transformed embryogenic lines survived the plant regeneration process so no whole plants were recovered. This result does indicate that it should be possible to insert genes into the plastid genome of the important crop soybean if the overall methods are improved.

  • Isoflavones 1-3 and pterocarpans 4-8 were isolated from methanol extract of roots of Glycine max. In inhibitory effect against human acyl-CoA:cholesterol acytransferase (ACAT)-1 and ACAT-2, glyceollin I 5 showed potent hACAT-1 ($IC_{50}=299.0{\mu}M$) and hACAT-2 ($IC_{50}=82.7{\mu}M$) inhibitory activities.

  • Probiotics are microorganisms that have beneficial effects on the health of the host. The health promoting effect by probiotics influences suppressing harmful bacteria, prevention of constipation, blood cholesterol reduction and regulation of blood pressure. Prebiotics are used to promote the growth or activity of microorganisms. Synbiotics, which are a mixture of probiotics and prebiotics, synergize in the intestines by complementing each other. Synbiotics not only improves the viability of the probiotics while passing through the gastrointestinal tract, maintain intestinal homeostasis, but also regulate balance of harmful and useful bacterial growth. Glycine max Merr (GMM) has been widely used in Asian countries to treat cancer, obesity, oxidative stress and imbalanced immune diseases. In addition, it has been reported that dietary fiber-rich grains promote bowel movements and prevent constipation. In this study, we investigated the viability of LactobacillIus buchneri (L.buchneri) strains, known as lactic acid bacteria under conditions of gastric fluid and intestinal fluid to determine the suitability of L.buchneri as probiotics. The adhesion ability of L.buchneri to caco-2 cells was also confirmed. The present studies showed that GMM extract promoted the growth and activity of L.buchneri strains as prebiotics. Also, this results suggested that the mixture of L.buchneri and GMM extract can helps maintain intestinal health and healthy body as synbiotics and health functional food material.

  • Protein kinase C, a protein related in PI cascade, was partially purified from the cytosol protein of etiolated plants of Glycine max by DEAE-52 cellulose chromatography and phenylsepharose chromatography. When the DEAE column was eluted with 0-0.8 M linear gradient KCl, tow fractions were found that increased the phosphorylation of histon H1 about five and nine-fold in the presence of 5 $\mu\textrm{g}$/mL phosphatidylserine and 0.5 $\mu\textrm{g}$/mL diolein, respectively. These fractions were used as DEAE pool. The reaction eluted with relatively high concentration of KCl was loaded on phyenylsepharose column with 5 mM CaCl2 and eluted with 1 mM EGTA. A fraction contained the protein kinase C, which increased the phosphorylation of the histon H1 was fractionated. To determine the molecular weight of PKC, the fraction eluted from phenylsepharose column was analyzed by 5~15% polyacrylamide gel electrophoresis after concentrated with the Amicon membrane (YM10). That revealed two bands corresponding to 60 and 65 kGy by silver staining of the gel, respectively.

  • ATP contents of soybean(Glycine max Merrill) and mungbean (Phaseolus radiatus L.) seeds being germinated with Hoagland solution at $30^{\circ}C$ for 6 days were determined. In pregerminated seed, ATP contents in soybean and mumgbean were 11.4 and 63.0$\mu$g/g fresh seed respectively. During germination, the highest ATP content of soybean seeds was 550% of initial content on 2nd day and that of mungbean was 480% on 1st day after germination. ATP content in cotyledon of soybean and mungbean were increased up to 4th and 1st day after germination respectively, thereafter both were decreased, but those in the root, including the hypocotyl, of both seeds were continuously increased with germination progress.
