    Autophagy contributes to enhancing the immune system (innate and adaptive immune system) against foreign pathogens. Autophagy of macrophages is used as a major indicator for developing vaccine adjuvants to increase the adaptive immune response. In this study, water extracts from Rosa acicularis leaves (RAL) increased the production of immunostimulatory mediators and phagocytic activity in RAW264.7 cells. RAL increased p62/SQSTM1 expression. Inhibition of TLR4, JNK, and PI3K/AKT blocked RAL-mediated increase of p62/SQSTM1. RAL activated JNK and PI3K/AKT signaling. RAL-mediated activations of JNK and PI3K/AKT signaling were reversed by TLR4 inhibition. Taken together, it is believed that RAL-mediated autophagy may be dependent on activating via TLR4-dependent activation of JNK and PI3K/AKT signaling in macrophages. - COLLAPSE

    To evaluate functional biomaterials of 5 invasive alien plants, total polyphenol and flavonoid contents, antioxidant activity, anti-inflammatory activity, and antibacterial effect were measured. The total polyphenol and flavonoid contents of the extracts were in the order of Rumex acetosella L. > Hypochaeris radicata L. ≥ Lactuca scariola L. > Humulus japonicus Siebold & Zucc. ≥ Solanum viarum Dunal. The DPPH and ABTS radical scavenging activities of the extract were the highest in R. acetosella and correlated well with the total polyphenol contents. In RAW 264.7 cells stimulated with lipopolysaccharide (LPS), nitric oxide (NO) and prostaglandin E2 (PGE2) production inhibitory effect of the extracts (100 ㎍ SE/mL) were 20~60% and 10~70%, respectively, showing the highest inhibitory effect in R. acetocella. The extracts of R. acetosella, H. japonicus and S. viarum showed antibacterial activity against food poisoning-causing microorganisms such as Bacillus subtilis, Escherichia coli, Vibrio parahaemolyticus and Vibrio vulnificus. Furthermore, the H. japonicus extract was found to have effective antibacterial activity against oral microorganisms such as Enterococcus faecalis, Lacticaseibacillus casei, Rothia dentocariosa, Staphylococcus epidermidis and Streptococcus mutans, and its major active ingredients were predicted to be pentadecylic acid, palmitic acid and clionasterol. These results suggest that alien plants have potential as biomaterials with antioxidant, anti-inflammation and antibacterial effects. - COLLAPSE

    Autophagy contributes to enhancing the immune system (innate and adaptive immune system) against foreign pathogens. Autophagy of macrophages is used as a major indicator for developing vaccine adjuvants to increase the adaptive immune response. In this study, PLR activated autophagy and increased p62/SQSTM1. The knockdown of p62/SQSTM1 attenuated PLR-mediated autophagy. Inhibition of TLR4 blocked PLR-mediated increase in p62/SQSTM1 level and autophagy induction. In addition, inhibition of PI3K blocked HSL-mediated increase of p62/SQSTM1. PLR increased Nrf2 level and the inhibition of TLR4 and PI3K reduced PLR-mediated increase of Nrf2. Taken together, it is believed that PLR may induce autophagy through upregulating p62/SQSTM1 via TLR4/PI3K/Nrf2 signaling pathway. - COLLAPSE

    Glycyrrhiza korshinskyi Grig. (Gk), which is a new variety of Glycyrrhiza, was developed by the National Institute of Horticultural and Herbal Science in Korea Rural Development Administration. It is improved the limitations of traditional Glycrrhiza species such as G. uralensis Fisch., G. glabra L., and G. inflata Batal. and has been reported various pharmacological effects. The aim of this study is to investigate the protective effect of Gk on the acute pancreatitis, because which has not been revealed yet. AP was induced via intraperitoneal injection of cerulein (50 ㎍/㎏) hourly for 7 times in C57BL/6 mice. Gk water extract (20 or 50 ㎎/㎏) or saline was administrated via oral gavage 1 h before the first injection of cerulein. The mice were sacrificed at 5 h after the final injection of cerulein. The inflammatory cell infiltration in pancreatic tissue was decreased by the administration of Gk water extract compared to the AP group. Also, serum amylase and lipase levels were decreased by the administration of Gk water extract compared to the AP group. These results suggest that Gk have protective effect on the acute pancreatitis. - COLLAPSE

    Several members of the genus Broussonetia are woody plants with high-quality cellulose fibers and are used to make a traditional type of Korean paper known as Hanji. Three of these species, Broussonetia kazinoki, Broussonetia monoica, and Broussonetia papyrifera, are found in the Korean Peninsula. Because it is challenging to distinguish different Broussonetia species based on morphology alone, we have developed a set of insertion/deletion (InDel) markers for genetic identification of these species. From twenty-two Broussonetia samples collected throughout Korea, we selected six for next-generation sequencing analysis. InDel marker candidates were identified by comparing this sequence information with the B. kazinoki chloroplast genome sequence. The marker candidates were used to screen the genomes of the twenty-two Broussonetia plants, and five useful chloroplast-based InDel markers were identified. Detailed genotyping using these five markers showed that the twenty-two plants of the genus Broussonetia could be clustered into five groups, verifying that the markers developed here can be used for breeding, identification, and analysis of species in the genus Broussonetia. - COLLAPSE

    Stellaria pallida (Dumort.) Crép., S. ruderalis M. Lepší, P. Lepší, Z. Kaplan & P. Koutecký, and Cerastium pumilum Curtis are unrecorded alien species of Caryophyllaceae found in Seoul and Gyeonggi-do in the Republic of Korea. Stellaria pallida is readily distinguished from other taxa in the same genus by its petals, as it’s considerably smaller than the sepals or absent. In contrast, S. ruderalis is difficult to identify as it has intermediate traits between S. media L. and S. neglecta (Lej.) Weihe. However, S. ruderlais clearly identified by seed morphology, and S. ruderalis, unlike S. media and S. neglecta, has conical shape of outer periclinal wall and papillate on the basely surface of that. Cerastium pumilum is similar to C. glomeratum Thuill. and belongs to the same subgenus (Sub gen. Fugacia); however, it has some distinct characteristics, including stamens that are primarily 8 (5-10), upper bracts with membranous edges, and the length of the pedicels and petals being longer than that of the sepals. The three of alien plants was recorded for the first time in this study, and information of their habitat, distribution map, description and photographs are presented. - COLLAPSE

    Developing and breeding improved legume-based food resources require collecting useful genetic traits with heritability even though requiring some time-consuming, costly, and labor intensive. We attempted to infer heritability of nine genetic traits—days to flowering, days to maturity, period from flowering to maturity, the number of seeds per pod, 100-seeds weight, and four contents such as crude protein, crude oil, crude fiber, and dietary fiber—using 455 homologous chloroplast gene sets of six species of legumes. Correlation analysis between genetic trait differences and phylogenetic distance of homologous gene sets revealed that days to flowering, the number of seeds per pod, and crude oil content were influenced by genetic factors rather than environmental factors by 62.86%, 69.45%, 57.14% of correlated genes (P-value ≤ 0.05) and days to maturity showed intermediate genetic effects by 62.42% (P-value ≤ 0.1). The period from flowering to maturity and 100-seeds weight showed different results compared to those of some previous studies, which may be attributed to highly complicated internal (epistatic or additive gene effects) and external effects (cultural environment and human behaviors). Despite being slightly unexpected, our results and method can widely contribute to analyze heritability by including genetic information on mitochondria, nuclear genome, and single nucleotide polymorphisms. - COLLAPSE

    The germination characteristics of Pseudolysimachion kiusianum var. diamantiacum (Nakai) T.Yamaz., a rare and endemic plant designated by the Korea Forest Service, were investigated according to light conditions, temperature, and pretreatment. As a result of the germination experiment according to light conditions, it was determined that P. kiusianum is a photoblastic seed that does not germinate at all in dark conditions. The optimum germination temperature of the seeds was found to be 20-25℃, considering the final germination rate and germination time. Three growth regulators (IAA, GA3, kinetin) and two inorganic salts (KNO3, KCl) were pretreated to improve the germination rate of P. kiusianum seeds. The growth regulators IAA and kinetin had no significant effect on improving the germination rate of P. kiusianum seeds. On the other hand, GA3 significantly increased the final germination percentage and germination rate regardless of the concentration, especially the treatment of more than 500 ㎎·L-1 at 20℃ was more than 4 times more effective than the untreated. The inorganic salts KNO3 and KCl had no significant effect on the seeds of P. kiusianum at low concentrations, but at higher concentrations (40 mM and 300 mM, respectively), they improved the germination rate and germination age by 2 times compared to the untreated. The results of this study will be useful for the mass propagation of P. kiusianum, which has the potential to be utilized as a native plant for restoration. - COLLAPSE

    The purpose of this study was to identify the propagation characteristics of Diabelia spathulata (Siebold & Zucc.) Landrein through seeding and cutting methods. The seed germination rate was meager (0.22~3.56%). In hardwood cutting, the highest rooting rate was 36.1% in sand + perlite (2:1) and 37.8% in 1000 ㏙ of IBA pre-treatment. Softwood cutting showed the highest rooting rate when the cutting diameter was 3 to 5 ㎜ and the cutting length was 7 to 8 ㎝. In particular, the highest rooting rate of 80% was observed in the sand among the 8 cultivation media treatments. In the case of root cuttings, the rooting rate was 83.3~96.7% in all cultivation media. The highest rooting rate was observed when the diameter of the cutting was 7 to 8 ㎜, and the length of the cutting was about 10 to 11 ㎝. Among cutting methods, root cutting showed the highest rooting rate. Division showed a 100% rooting rate regardless of size or growth status. For Diabelia spathulata (Siebold & Zucc.) Landrein, propagation by cuttings was more efficient than seeding. However, Further research on the morphophysiological dormancy and dormancy break of seeds is needed for seed propagation. - COLLAPSE

    Peucedanum japonicum Thunberg is a biennial plant that usually flowers and dies after seed setting at 2nd year. We inspected the flowering and fertilization characteristics to establish the breeding system. The plant forms complex umbel inflorescences consisting of multiple umbellets and numerous flowers. Each flower is bisexual but allogamous because of protandry. A flower bloomed for three days with matured pollen and no stigma appearance. Inspection of pollen tube growth indicates that the pollen viability can be maintained for up to 3~7 days after first flowering (DAF). In a umbellet, flowers bloomed during 1~5 DAF and the pollen maintained viability during 3~10 DAF, and the pistil developed and maintained fertility during 8~12 DAF. Theoretically, self-pollination can be possible during 8~10 DAF in the same umbellet. Approximately 4.4% of seeds were developed by self-pollination among flowers in an enveloping solitary umbel. There is at least a 9~10 days difference for the development of an umbel with another umbel at the next branch, which indicates pollination can be permitted between different branches in an individual plant. Finally, we have established a rapid breeding method to shorten the breeding cycle to one year from two years by integrating the flowering and pollination characteristics. - COLLAPSE

    Sesame (Sesamum indicum L.) is an ancient oilseed crop, which is usually cultivated for its seeds. Sesame breeding aims to achieve high seed yield and quality, along with resistance to biotic or abiotic stresses. It is estimated that sesame is originated from Asia or Africa continent. In this study, we characterized 10 agronomic traits and evaluated lignan contents in 165 sesame germplasm originated from Asia or Africa, to select high-yield or high-lignan content accessions. Sesame germplasm showed diverse phenotypes and highly variable lignan contents (sesamin: 0.5-12.6 ㎎/g, sesamolin: 0.1-3.5 ㎎/g, lignan: 1.1-16.1 ㎎/g). Based on originated continent, there are significant difference in agronomic traits, but no in lignan content. Correlation analysis revealed that yield-related agronomic traits were negatively related with lignan contents. Also, PCA analysis showed that most agronomic traits and lignan contents were principal components explaining diversity of whole sesame germplasm. Sesame germplasm was clustered into three groups based on agronomic traits and lignan contents. Finally, we selected high-yield (IT29416, IT167042, K276848, K276849) and high-lignan candidate accessions (IT169254, IT170031, IT169250, IT154876, IT170034), respectively. These accessions are expected to be valuable resources for breeding of high-yield and high-lignan contents functional cultivars. - COLLAPSE
