Analysis of Phylogenetic Relationship in Platycodon grandiflorum using RAPD Molecular Marker
Jemin Yoo,So Hyeon Park,Yurry Um,Yi Lee 한국육종학회 2015 한국육종학회 심포지엄 Vol.2015 No.07
Platycodon grandiflorum is a perennial herbal plant belongs to Campanulaceae family. It has very important genetic value as a major plant in Asterids order. The major ingredients are platycosides, terpenoid saponins. In Korean industrial plants market, it was produced 5,633 tons in 2013, and the total amount of production was less than only five species, omija, ginger, raspberry, yam and deodeok. P. grandiflorum is called ‘Gilgyung’ and is used as a fresh vegetable and an ornamental plant. Nowadays, various components of P. grandiflorum were already published. But, genetic research is in the starting stage. In this study, 11 cultivars; 1. MariesⅡ, 2. Hakone double white, 3. Hakone double blue, 4. Fuji white, 5. Fuji pink, 6. Fuji blue, 7. Astra white, 8. Astra pink, 9. Astra blue, 10. Astrasemi double blue, 11. Jangback, were analyzed using 60 Operon Universal RAPD primers. The results were phylogenetically analyzed and related to the morphological characteristics of the cultivars.

M3HB (Methyl 3-hydroxybutyrate), known as an alternative energy source for cells with impaired metabolicfunction, has recently been reported to have therapeutic effects on Alzheimer’s disease and inhibitionof apoptosis. In this study, the enzymatic conversion of M3HB from methanol and betahydroxybutyricacid (BHB) by lipase-catalyzed esterification was performed for the first time. The reactionconditions for maximum M3HB conversion were as follows: Novozym 435, 15 g/L; BHB:methanolmolar ratio, 1:2; reaction temperature, 40 C; and organic solvent, chloroform. The lipase-based M3HBsynthesis achieved about 94.6% conversion through a step-by-step optimization, and is expected to contributeto future bioindustry applications.

It is expected that mobile internet will lead the growth of broadcasting and telecommunications industry. Given that key of internet development was openness, the positive future of mobile internet also relies on openness. Mobile internet was estimated as closed structure because of mobile carriers’ power, and the increase of smart phone seems to bring relatively open structure in mobile internet. But we still cannot estimate mobile internet as entirely open structure, because the device platform is emerging out as new control power instead of mobile carrier. In this context, we focus on the considerable regulation to preserve of mobile internet openness.
Identification of Expansin Genes in Platycodon grandiflorum A. Using RNA-seq Analysis
Sang Ik Park,Jemin Yoo,Yurry Um,Yi Lee 한국육종학회 2015 한국육종학회 심포지엄 Vol.2015 No.07
Platycodon grandiflorum A. is a perennial plant belongs to Campanulaceae family. This plant has been used herbal medicine ingredient in East Asia. Because of the high saponin content, it is an economically important medicinal plant in Korea. It has been reported that saponins of P. grandiflorum were mainly synthesized in root tissues. The studies about root growth of the plant were few. Expansin is an important protein playing a role in root growth of plants, and is known as a nonenzymatic protein. Expansins are novel plant cell wall loosening proteins leading to turgor-driven cell extension. Expansin encoding genes exist in multigene family, and there are more than 30 genes in Arabidopsis thaliana. and more than 50 genes in Oryaza sativa. Therefore, identification of the genes was difficult in P. grandiflorum because of the lack of genome sequence. Recently, the development of next generation sequencing (NGS) technologies make it possible to obtain the target genes sequences rapidly and precisely. In this study, to identify the expansin encoding genes in P. grandiflorum, we used RNA-seq analysis with Illumina HiSeq platform. We analyzed whole transcriptome of P. grandiflorum through the RNA-seq analysis based on next generation seuqencing. CLC Genomics Workbench software (Clc Bio inc.) was used for assembly. We assembled 122,663 contigs and search 123 contigs were identified from the search using 61 expansin gene

Objective: Little is known about factors influencing of hippocampal metabolism (HM) in mild cognitive impairment (MCI). Our objective was to determine whether HM in patients with amnestic MCI (aMCI) is decreased than non-amnestic MCI (naMCI). Methods: Overall, 32 MCI patients underwent 18F-fluorodeoxyglucose-positron emission tomography. They were characterized as aMCI (n=18) or naMCI (n=14) according to comprehensive neuropsychological criteria. Analysis of variances were used to assess differences on HM between aMCI and naMCI after controlling age, sex, education and Korean version of Mini Mental Status Examination. Results: We found that HM was more decreased in aMCI than naMCI. This result was not changed after controlling hippocampal volume. Conclusion: Our findings suggest that aMCI is associated with decreased HM in MCI.
