Supplying sufficient rice to growing populations is a global challenge. Hybrid indica rice varieties exploiting heterosis have increased yields, but inter-subspecific crosses between indica and japonica varieties are hampered by sterility. Examination and genetic understanding of yield heterosis in indica/japonica crosses addressing yield barriers are basic requirements. In this study, QTLs for heterosis of yield traits were identified in indica-japonica recombinant inbred lines (RILs) using a total of 178 RILs originating from Dasanbyeo (indica) × TR22183 (japonica) (DT-RILs) and their backcrossed populations. Nine of sixty-six major quantitative trait loci (QTLs) identified in DT-RILs exhibited heterosis. Heterosis QTLs clustered with other traits on chromosomes 1, 4, and 8, and clusters were conserved between different RILs. The clusters contained several known yield enhancement genes/QTLs. Specific heterotic allele combinations contributed to four major heterosis QTLs, particularly for panicle and spikelet number traits. Heterosis for yield and yield-related traits was explained by the harmonized effects of overdominance, dominance, and epistatic interactions in inter-subspecific breeding populations.

Purpose: The purpose of this study is to find out the effect and chacrtaeristics of training according to the technical differences of drop jump by examining the effect of 6 weeks of depth jump & drop jump training on the isokinetic strength and agility performance. Method: Nineteen collegiate Students participated in the present study and were randomly assigned to 6 weeks of depth jump (DEJ) or drop jump (DRJ) training twice a ewek. Data on the measured variables (isokinetic strength of knee flexion and extension, the height of avertical jump, and agility test) were collected before and after a 6-week training period. A 2×2 analysis varniace (two factors mixed-effects ANOVA) was used for the statical analyses. The significant level of hypothesis verification is set-up as α=.05. Results: The results of this study are as follows. 1) The 6 weeks of edpth jump training significantly improved isokinetic strength & average power (60°/sec, 180°/sec, and 300°/sec speed condition), vertical jump performance, and agility (p<.05). 2). The 6-week drop jump training significantly improved agility (p<.05), but the isokinetic strength, average power, and vertical jump performance did not indicate significant improvement. 3) There were no significant differences between depth jmup (DEJ) & drop jump(DRJ) training on th e measured variables (isokinetic strength of knee flexion & extension, the height of vertical jump, and agility test) after 6 weeks of training (p<.05). Conclusion: It is supported that depth jump (DEJ) and drop jump (DRJ) tirnaing is an optional and usefu l method that can be used to increase isokinetic strength, powe r,and agility in the final preparation phase o f athletes before the competition season.

김창국,전영아,조규택,권순우,김용환,홍승범 한국유전체학회 2009 Genomics & informatics Vol.7 No.1
The Korean Agricultural Culture Collection (KACC) has developed a web-based system to provide an integrated database with information updates about microbial resources. This integrated database consists of 5 major functions and contains general information, which includes identification numbers, culture media composition, image information, DNA sequences, patent information, and general forms for ordering and depositing microorganisms. In 2008, KACC started providing characterization information. KACC maintains 9,801 cultures of microorganisms, including 3,296 strains of bacteria, 4,734 fungi, 784 actinomycetes, 64 yeasts, and 923 others.

김창국,설영주,박동석,한장호 한국유전체학회 2011 Genomics & informatics Vol.9 No.2
The National Agricultural Biotechnology Information Center (NABIC) constructed an agricultural biology-based infrastructure and developed a biological informationbased database. The major functions of the NABIC are focused on biotechnological developments for agricultural bioinformatics and providing a web-based service to construct bioinformatics workflows easily, such as protein function prediction and genome systems biology programs. The NABIC has concentrated on the functional genomics of major crops, building an integrated biotechnology database for agro-biotech information that focuses on the proteomics of major agricultural resources,such as rice, Chinese cabbage, rice Ds-tagging lines, and microorganisms.

Anthocyanin is a major class of flavonoids that tissues produce in response to environmental signals. The pigmentation of colored rice was analyzed by oligo microarray based on two factors, cultivar and developmental stage. As many as 250 and 350 genes were identified to be significantly up- and down-regulated. Using hypergeometric analysis for transcription factor function, the Myb and GT families, PBP, PBF, RAV, and STF factors were identified have potential anthocyanin-specific functions. We also obtained seventeen unknown genes which display novel functions. Among the genes within the GT-1 and Myb1 groups, three unknown genes were found to be upregulated significantly in both combinations of cultivar and developmental stage. These results showed functional diversity of TF families and that the biological functions of the particular TFs may be activated in a pigmentation pathway in rice.

김창국,오재현,나종국,조철오,김경화,유고은,김둘이 한국육종학회 2019 Plant Breeding and Biotechnology Vol.7 No.4
We have developed a multi-layer pipeline that uses transcriptomic data to identify candidate genes associated withcomplex pathways in plants. We used this multi-layer approach, incorporating microarray, RNA sequencing, polymerase chain reaction(PCR), and protein-protein interaction analyses, to identify 14 genes associated with drought tolerance in potato. We generatedtransgenic potato lines that over-express bZIP28, one of the genes selected by our pipeline, to confirm the involvement of that gene indrought tolerance. The protein interactions of the products of the screened genes were assessed using yeast two-hybrid and bimolecularfluorescence complementation analyses. Overall, this study demonstrated the utility of our multi-layer approach for decipheringcomplex biosynthetic pathways using transcriptomic data.
