  • The advent of next generation sequencing technology has elicited plenty of sequencing data available in agriculturally relevant plant species. For most crop species, it is too expensive to obtain the whole genome sequence data with sufficient coverage. Thus, many approaches have been developed to bring down the cost of NGS. Genotyping-by-sequencing (GBS) is a cost-effective genotyping method for complex genetic populations. GBS can be used for the analysis of genomic selection (GS), genome-wide association study (GWAS) and constructing haplotype and genetic linkage maps in a variety of plant species. For efficiently dealing with plant GBS data, the TASSEL-GBS pipeline is one of the most popular choices for many researchers. TASSEL-GBS is JAVA based a software package to obtain genotyping data from raw GBS sequences. Here, we describe application of GBS and bioinformatics pipeline of TASSEL-GBS for analyzing plant genetics data.

  • Anthocyanins are known to be involved in various functions such as antioxidant and antibacterial activities in plants. Although studies on anthocyanins in corn have been conducted recently, basic research related to anthocyanin biosynthesis is insufficient. In this study, we examined the molecular biological and physicochemical properties related to anthocyanin biosynthesis in the tassel and silks of Gwangpyeongok and Dacheongok cultivars. Anthocyanins were not synthesized in either the tassel or silks in Gwangpyeongok, whereas were synthesized in both in Dacheongok. The total anthocyanin content was approximately 30 times higher in the tassel and silks of Dacheongok than in those of Gwangpyeongok. In addition, C-3-G was measured only in the tassel of Dacheongok, and C-3-G, Pg-3-G, and M-3-G were 45.2 times, 27.3 times, and 37.6 times higher, respectively, in the silks of Dacheongok than of Gwangpyeongok. Expression of F3'H, DFR, and GST genes decreased in the tassel, and that of F3'H and DFR genes decreased in the silks of Gwangpyeongok. It was further confirmed that transcription factor P1 and R1 regulate the expression of anthocyanin biosynthetic genes in the tassel and silks, respectively, in Gwangpyeongok. Linoleic acid (C18:2) decreased by 6.6% and 10.9%, and linolenic acid (C18:3) increased by 8.5% and 8.5%, in the tassel and silks, respectively, of Gwangpyeongok compared to those of Dacheongok. Palmitic acid (C16:0) increased by 4.1% and oleic acid (C18:1) decreased by 2.1% in the silks of Gwangpyeongok compared to that in Dacheongok. In addition, the total fatty acid content in the tassel and silks increased by 10.3% and 30.4%, respectively, in Gwangpyeongok compared to that in Dacheongok. However, no significant results were observed in the analysis of phytosterol components. These results may be utilized as useful resources for the development of functional corn containing a large amount of anthocyanins.

  • One row of pollen parent to two rows of seed parent (1:2), 2:4 and solid (1:2) planting patterns (PP) were compared in seed parent densities of 3,500, 5,000 and 6,500 plants per 10 ares to determine effects of PP and plant density on growths of seed and pollen plants, and seed yield of seed parent of modified single cross corn hybrid. Planting pattern did not significantly affect agronomic characteristics of seed plant except ear number per 100 plants and seed yield which were greater in solid and 1:2 PP than in 2:4 PP. Significant PP x plant density interaction did not exist for agronomic characteristics of seed parent. In the seed parent, plant height and 100 kernel weight were not affected by plant density, but ear height, ear number per 100 plants, and kernel number per ear were linearly decreased with increased plant densities. Seed yield ranged from 330 to 460 kg per 10 ares and overall yield response to plant density was quadratic. Tassel length and spikelet number per tassel of the pollen parent were significantly affected by PP and plant density. Significant PP x plant density interaction existed for tassel length and spikelet number per tassel. Tassel length and spikelet number per tassel were greater in 1:2 and 2:4 PP compared to solid PP and were greatly reduced with increased plant densities in solid and 1:2 PP. The results indicated that 1:2 or 2:4 PP at around 5,000 plants per 10 ares for seed parent would be suitable for seed production of modified single cross com hybrid.

  • The purpose of this study was to analyze the formative costume of Baroque style and to in-vestigate the characteristic of loop and tassel which are the main factors of decoration in the Post-modern clothing in point of the characteristic of retro. For this purpose, theoretical studies about the concepts of Post-modernism and aesthetic sphere o Baroque style were preceeded. Especially the parody which is concept that is the most influencing to the contemporary art, architecture, and costume. It is the identity of the parody that is being understood smoothly the creation and the imi-tation which is contrasted each other. The parody is urging the purpose rather than the essence and the recreation rather than the originality of the original works. The synthetic results were as follows ; 1. The frequent usage of loop and tassel which was expressed in the first half of 1990's in the modern clothing influenced the aes-thetic will of aspiration about the past. 2. The characteristic of retro to the tra-ditional form constitutes a base of spiritual thinking of Post-modernism which has been expressed in 1970's afterwards. The peculiarity about the great change in the traditional concept of artistic creation in the Post-modern clothing is the very extention of a range of application about the retro in which it becomes the essence or the oppor-tunity in artistic creation.

  • Recently, the most popular technique to determine the Genotype, genetic features of individual organisms, is the GBS based on SNP from sequences determined by NGS. As analyzing the sequences by the GBS, TASSEL is the most used program to identify the genotypes. But, TASSEL has limitation that it uses only the partial sequences that is obtained by NGS. We tried to improve the efficiency in use of the sequences in order to solve the limitation. So, we constructed new data sets by quality checking, filtering the unused sequences with error rate below 0.1% and clipping the sequences considering the location of barcode and enzyme. As a result, approximately over 17% of the SNP detection efficiency was increased. In this paper, we suggest the method and the applied programs in order to detect more SNPs by using the disused sequences.

  • The purpose of this study is to provide ideas for the development of bag design by analyzing the expression types and aesthetic formativeness of modern bag design using tassels and fringe given the newtro trend pursuing analog sensitivity in modern society. The methods and scope of this study are as follows. First, the related literature and internet data were reviewed in order to examine the expression types and characteristics of the bags of the West and East. Next, the definition and characteristics of tassel and fringe decoration in terms of the history of clothing were analyzed. Finally, the expression types and aesthetic formativeness of tassels and fringe were derived through the analysis of modern bag design shown in the fashion collections since 2010. The bags decorated with the tassels and fringe bring a variety of visual effects depending on the attachment position, direction and material composition, concentrating the gaze and radiating original style. In this study, the expression of tassels and fringe in modern bag design was classified into three types: surface decoration, shape variability, and object combination. Next, the aesthetic formativeness of modern bag design using tassels and fringe as decorative elements appeared through the mixture of heterogeneous materials and playfulness through imagination, exaggeration through extension of length and volume, and retro characteristics through reinterpretation of tradition. This study is expected to contribute to creative ideas of modern bag design which requires a global sense, which has been used in various cultures for a long time.
