  • This study investigate the effects of extracts of five species of Korean native forest plants on lipid accumulation and reactive oxygen species (ROS) production during the differentiation of 3T3-L1 cells. Our results show that Korean native forest plants extracts significantly reduced lipid accumulation and ROS production during adipogenesis in 3T3-L1 cells. Especially, Rubus coreanus Miq. was most effective in the inhibition of lipid accumulation and ROS production at a concentration of $100{\mu}g/mL$. Moreover, Rubus coreanus Miq. extracts significantly inhibited adipocyte differentiation, which is dependent on down-regulation of peroxisome proliferator-activated receptor gamma, CCAAT/enhancer-binding protein alpha, and adipocyte-specific fatty acid binding protein, a key adipogenic transcription factor. Therefore, these results suggest that Rubus coreanus Miq. might be a valuable source of bioactive compounds with anti-adipogenic activity.

  • Trace metals in honey have an influence on the taste of honey along with pollens. Western bee honeys, which are mostly collected from acacia, have less than 0.1% of ash. Savor of Korean native-bee honey is thought to be due to the difference of the contents of trace metals. Korean native-bee honeys collected from Jirisan District, which is the greatest producing area of native-bee honey in Korea, showed high contents of ash. Korean native-bee honeys from the districts other than Jirisan District also showed similar results($0.44{\sim}0.83%$ of ash) to those from Jirisan District. Potassium was found to be the principal factor of high content of ash with over 85% of trace metals in ash.

  • Ethnobotanical knowledge on native plants is critical on the conservation and management of biological resources. We investigated traditional knowledge of ethnobotanical uses in the Mt. Gayasan National Park area. Interviews were carried out to 189 residents at 176 places, and verified species and usage information was categorized by taxonomic groups, usage, and used parts. The ethnobotanical species of the regions consisted of a total of 275 taxa in 91 families including 105 cultivars. Sunflower family (Asteraceae) is the most widely used family with 30 taxa (7 cultivars). Rose family (Rosaceae, 25 taxa with 11 cultivars), Bean family (Fabaceae, 15 taxa with 11 cultivars), Grass family (Poaceae, 15 taxa with 10 cultivars), and Lily family (Liliaceae, 14 taxa with 4 cultivars) followed. About 50 taxa belong to the Approved Species for Delivering Overseas designated by Korea Ministry of Environment, and six Korean endemic taxa have been traditionally valuable in the regions. Many cultivated species have been utilized for various purposes accompanied local and native plants. The main usage of the plants are edible (175 taxa) and medicinal (168 taxa). Leaves are most commonly used parts (105 taxa), followed by stems (93 taxa), fruits (73 taxa), roots (55 taxa), and wholes (54 taxa). The study does not only provides examples of traditional uses of native plants, but also facilitates conservation of natural resources and sustainable developments of ethnobotanical knowledge for the contemporary human society.

  • Prunus glandulosa Thunb. [=Cerasus glandulosa (Thunb.) Sokolov] (Rosaceae) is native to the warmtemperate region of China (Anhui, Fujian, Guangdong, Guangxi, Guizhou, Hebei, Henan, Jiangsu, Shaanxi, Shandong, Sichuan, Yunnan, and Zhejiang Provinces). It is naturalized in the United States (i.e. Alabama, Michigan and North Carolina) and Canada (Ontario). This species, previously only recorded as introduced or cultivated plants on the Korean Peninsula, was confirmed to be naturally distributed in the southwestern coast islands(i.e. Geomun-do, Chuja-do and an uninhabited island in Shinan-gun of Jeollanam-do). Prunus glandulosa Thunb. is distinguished from a related taxon P. japonica var. nakaii (H. Lév.) Rehder by pedicel 8-12 (-16) mm long, linear stipules, glabrous style, and pink petals. The morphological characters and illustration of P. glandulosa Thunb. are provided with line drawings and photographs from the natural habitat. In addition, it is likely that a new habitat will be found by plant biodiversity investigations through the southwestern coast islands. Further research is needed to determine its population size, distribution, and threats, as well as identify appropriate locations for conservation collection of germplasm.

  • Plants are the promising reservoirs for natural products with their diverse secondary metabolites. Many invasive plants have been introduced in Korea, which adversely affect on the native ecosystem but holds difficulty removing them due to their proliferation. In this study, we evaluated disease control efficacy of methanol extracts from four invasive plant species against 7 representative crop pathogens. Methanol extract of Phytolacca americana effectively suppressed rice blast, tomato gray mold, and tomato late blight in a dose dependent manner. The methanol extract of Amorpha fruticosa also exhibited potent antifungal activity against pepper anthracnose in a concentration dependent way. These data suggest that the extracts of P. americana and A. fruticosa can be developed as plant disease protection agents against rice blast, tomato gray mold, tomato late blight, and pepper anthracnose. Furthermore, more extensive research will be required to identify and isolate active compounds from problematic invasive plant species to develop valuable agrochemicals.

  • A scientific name is one of changeable terms in biology whenever additional research results of specific taxa is accumulated. The Database of the National Species List of Korea (DBNKo) was developed to manage taxonomic information of Korean species, designed to describe the changeable and complex taxonomical structure and information. A Korean Taxonomical Serial Number (KTSN) was assigned to each taxon, different from the normally used systems that the scientific name was considered as primary key to manage higher rank of taxa systematically. Common names were also treated with the KTSN, reflecting that common name is considered as one type of taxon. Additional taxonomic information (e.g., synonyms, original names, and references) was also added to the database. A web interface with an intuitive dashboard presenting taxonomic hierarchical structure is provided to experts and/or managers of the DBNKo. Currently, several biological databases are available in the National Institute of Biological Resources (NIBR) such as a specimen database, a digital library, a genetic information system, and the shared species data based on the DBNKo. The DBNKo started sharing species information with other institutions such as the Nakdonggang National Institute of Biological Resources. It is an ideal centralized species database to manage standardized information of Korean species.

  • Native corn starch and montmorillonite caly nanocomposites were prepared using the glycerol as the plasticizer. These were characterized by mechanical analysis, X-ray diffraction, infrared spectroscopy, differential scanning calorimetry, and scanning electron microscopy. The tensile strength increased with the clay content to a maximum point and then decreased due to gapping between the two phases. Dispersion of the layered silicate within the starch was verified using X-ray diffraction pattern. Examination of these materials by scanning electron showed that intercalates have good wetting to the starch surface.

  • Osteopontin (OPN) is a secreted phosphorylated glycoprotein. It has an important role in multiple biological processes including cell survival, bone remodeling, inhibition of ectopic calcification, as well as, is thought to have potential immune modulation activities. In this work, we isolated and characterized a full-length open reading frame (ORF) of Korean native cow's OPN from Korean native cow's (Hanwoo) kidney, and successfully cloned firstly on Hanwoo's OPN. The sequencing results indicated that the isolated cDNA was 1190 bp in length containing a complete ORF of 837 bp. It encoded a precursor protein Hanwoo's OPN consisting of 278 amino acids with a signal peptide of 16 amino acids. Amino acid homology was found to be 99.3% as compared to the corresponding sequences of Holstein bone marrow OPN. Hanwoo's kidney OPN and Holstein bone marrow OPN are different only in two amino acid residues 42 and 56, amino acid residue 42 is Thr (T) ${\leftrightarrow}$ Ile (I), and amino acid residue 56 is Ala (A) ${\leftrightarrow}$ Thr (T) respectively. These results from the present work would be helpful to elucidate the biological function of Hanwoo's OPN and provided a foundation for further insight into role of Hanwoo's OPN.
