    In order to select potential plant resources as functional materials and natural antioxidants, we evaluated antioxidant activity and serotonin derivatives of safflower germplasm collected from five countries. N-(p-Coumaroyl) serotonin (CS) and N-feruloylserotonin (FS) were analyzed by using Ultra Performance Liquid Chromatography (UPLC). Total polyphenol content (TPC) was determined by Folin-Ciocalteu method and antioxidant activities were estimated by 2,2-diphenyl-1-picryl-hydrazil (DPPH), 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) diammonium salt (ABTS), Ferric reducing antioxidant power (FRAP) and Reducing power (RP) assays. The TPC showed a range of 28.25 to 90.53㎍ gallic acid equivalent (GAE)/㎎ dried extract (DE). DPPH, ABTS, FRAP and RP assay were in the range of 18.76 to 93.98, 48.91 to 163.73, 3.80 to 132.29 and 26.32 to 80.08 ㎍ ascorbic acid equivalent (ASCE)/㎎ DE, respectively. Among the five countries, safflower seed collected from Iran had the highest levels of serotonin derivatives and antioxidant activities than other countries (p<0.05). CS showed high correlation with TPC, ABTS and DPPH (r=0.673,0.727,0.820), and FS showed high correlation with DPPH (r=0.740). Accessions IT321214 and IT321215 could be useful for development of new functional materials and could be used as a source of valuable natural antioxidant materials. - COLLAPSE

    This study describes a preliminary evaluation of the anti-inflammatory activity and anti-atopic activity of Phormium tenax leaf extracts. P. tenax leaf was extracted using 70% ethanol and then fractionated sequentially with n-hexane, methylene chloride, ethyl acetate, n-butanol. In order to effectively screen for anti-inflammatory agents, we first investigated the inhibitory effects of P. tenax leaf crude extracts and solvent fractions on production of pro-inflammatory factors[nitric oxide(NO), prostaglandin E2(PGE2), inducible nitric oxide synthase(iNOS) and cyclooxygenase-2(COX-2)] and pro-inflammatory cytokines [tumor necrosis factor-α(TNF-α), interleukin-6(IL-6) and interleukin-1β(IL-1β)] in lipopolysaccharide(LPS)-stimulated RAW 264.7 cells. In addition, we also evaluated of their inhibitory effect on the atopic dermatitis-like inflammatory markers such as macrophage-derived chemokine(MDC) and thymus and activation-regulated chemokine(TARC) in HaCaT cells. Among the five solvent fractions of P. tenax, methylene chloride and ethyl acetate fractions inhibited production of pro-inflammatory factors and pro-inflammatory cytokines in a dose dependent manner, respectively. These fractions were also showed inhibitory activity for MDC and TARC expression levels in IFN-γ-stimulated HaCaT cells, respectively. These results suggest that P. tenax have significantly effects of anti-inflammatory activity and anti-atopic activity that might be beneficial for the topical treatment of inflammatory skin disorders. - COLLAPSE

    In this study, we evaluated the effect of Rodgersia podophylla leave extracts (RPL) on β-catenin level in human cancer cells. RPL dose-dependently inhibited cell proliferation in SW480, A549, MDA-MB-231, PC-3 and AsPC-1 cells. RPL dramatically decreased β-catenin protein level in all cancer cells. However, decreased level of β-catenin mRNA expression was observed in A549 and AsPC-1 cells. In addition, RPL dramatically attenuated cyclin D1 mRNA expression in all cancer cells. MG132 decreased the downregulation of β-catenin protein level induced by RPL in all cancer cells, while RPL-induced downregulation of β-catenin was inhibited by the inhibition of GSK-3β by LiCl in MDA-MB-231 cells. RPL phosphorylated β-catenin and GSK-3β. In addition, the inhibition of GSK-3β by LiCl attenuated RPL-induced β-catenin phosphorylation. Based on these findings, RPL may be a potential candidate for the development of chemopreventive or therapeutic agents for human cancer. - COLLAPSE

    This study was conducted to investigate seed dormancy type and germination characteristics of Lonicera chrysantha. In imbibition test, the seeds imbibed water readily. Therefore, the seeds did not have physical dormancy (PY). The seeds have undeveloped embryo at seed dispersal and, then the E:S ratio (embryo/seed ratio) increased more than about 46% just before germination. In temperature experiments (5, 15, 20 and 25℃), the seeds did not germinate during incubation at 5℃. At 20℃, the seeds started to germinate from a week after sowing and the final germination was 86.7% at 2 weeks after sowing. At 15℃, the seeds started to germinate at 2 weeks and the final germination rate was 75.0% at 4 weeks after sowing. At 25℃, the seeds started to germinate at a week and the final germination rate was 48.3% at 19 weeks after sowing. Consequently, Optimum temperature of germination is 20℃ that shown highest final germination rate and shortest mean germination time. The seeds germinated all temperature treatments within 4 weeks except to 5℃. Therefore, it is concluded that seeds of L. chrysantha have only morphological dormancy (MD). - COLLAPSE

    The study was carried out to investigate growth of 48.6-L pot-cultivated 1-year-old ‘Fuji’/M.9 apple trees depending on different levels of nitrogen concentration. While rise in tree growth was paralleled with increase of nitrogen concentration, more than 32 mM of nitrogen rather restrained tree growth. In particular, growth of 16 mM of nitrogen treated trees was satisfied with criteria for production of high-quality pot-cultivated nursery stocks. Although mineral contents of leaves were higher in 8 and 16 mM nitrogen treatments than commonly recommended mineral contents in apple orchards, such somewhat surplus minerals could be helpful for tree growth after transplanting to apple orchards. In addition, our result indicated that soils of 8 and 16 mM of nitrogen treated pots met appropriate criteria for soil chemical property of apple orchards. Thus, in the light of tree growth, mineral contents of leaves, and soil chemical property in the pots, 16 mM of nitrogen treatment is considered to be suitable for production of 1-year-old ‘Fuji’/M.9 apple potted trees. - COLLAPSE

    Twenty soybean cultivars developed recently were assessed using 27 insertion and deletion (InDel) markers derived from dense variation blocks (dVBs) of soybean genome. The objective of this study is to identify the distinctness and genetic relationships among a total of 169 soybean accessions including new cultivars. The genetic homology between 149 accessions in the soybean barcode system and 20 new cultivars was 61.3% on average with the range from 25.9% to 96.3%, demonstrating the versatile application of these markers for cultivars identification. The phylogenic analysis revealed four subgroups related to their usage. The 80% of cultivars for vegetable and early maturity and the 65.9% of cultivars for bean sprouts were clustered in subgroup I-2 and II-2, respectively, indicating of the limited gene pools of their crossing parents in breeding. On the other hands, the cultivars for soy sauce and tofu with considerable gene flow by genome reshuffling were distributed evenly to several subgroups, I-1 (44.4%), I-2 (26.4%) and II-2 (23.6%). We believe that the 27 InDel markers specific to dVBs can be used not only for cultivar identification and genetic diversity, but also in breeding purposes such as introduction of genetic resources and selection of breeding lines with target traits. - COLLAPSE

Guryong was classified as a total of 526 taxa comprising of 87 families, 298 genus, 449 species, 4 subspecies, 63 varieties, 10 forma. Among them, the endemic plants in Korea were investigated as 10 taxa of including Pseudostellaria coreana (Nakai) Ohwi. The Korean rare plants species were investigated as 16 taxa, among them degree of CR investigated as 1 taxa of Cypripedium macranthum Sw., VU investigated as 5 taxa of including Rhododendron micranthum Turcz., degree of LC investigated 9 taxa of including Clematis koreana Kom., degree of DD investigated 1 taxa of Adenophora grandiflora Nakai. Endemic plants were investigated as 14 taxa of including seudostellaria coreana (Nakai) Ohwi and The floristic special plants were a total of 84 taxa such as 2 taxa in degree V(in cluding Polypodium virginianum L.), 7 taxa in degree IV (including Anemone reflexa Steph. & Willd.), 21 taxa in degree III(including Celtis aurantiaca Nakai), 22 taxa in degree II (including Thelypteris phegopteris (L.) Sloss.) and 31 taxa in degree I (including Cimicifuga simplex (DC.) Turcz.) was carried out to provide basic data. The naturalized plants were investigated as 37 taxa of including Chenopodium ficifolium Smith., Thlaspi arvense L., Rumex crispus L. and the percentage of urbanization index was 11.53%, the naturalized ratio was 6.99% respectively. - COLLAPSE
