Rathayibacter tritici, which is a Gram positive, plant pathogenic, non-motile, and rod-shaped bacterium, causes spike blight in wheat and barley. For successful pathogenesis, R. tritici is associated with Anguina tritici, a nematode, which produces seed galls (ear cockles) in certain plant varieties and facilitates spread of infection. Despite significant efforts, little research is available on the mechanism of disease or bacteria-nematode association of this bacterium due to lack of genomic information. Here, we report the first complete genome sequence of R. tritici NCPPB 1953 with diverse features of this strain. The whole genome consists of one circular chromosome of 3,354,681 bp with a GC content of 69.48%. A total of 2,979 genes were predicted, comprising 2,866 protein coding genes and 49 RNA genes. The comparative genomic analyses between R. tritici NCPPB 1953 and R. toxicus strains identified 1,052 specific genes in R. tritici NCPPB 1953. Using the BlastKOALA database, we revealed that the flexible genome of R. tritici NCPPB 1953 is highly enriched in ‘Environmental Information Processing’ system and metabolic processes for diverse substrates. Furthermore, many specific genes of R. tritici NCPPB 1953 are distributed in substrate-binding proteins for extracellular signals including saccharides, lipids, phosphates, amino acids and metallic cations. These data provides clues on rapid and stable colonization of R. tritici for disease mechanism and nematode association.

The purpose of this study is to identify the effects of blood glucose and growth hormone on performance by complete loss of sleep and caffeine intake on 1 day of growing archery athletes. As a subject of study, 6 middle school male archery athletes applied repeated measurement method in the same group, The measured items were analyzed with the SPSS 20.0 statistical program. and 30M records were analyzed by using One-Way Repeated Measure ANOVA. Their heart rate, glucose, and growth hormone were analyzed by using Two-Way Repeated Measure ANOVA. The results show that caffeine intake after sleep loss influences heart rate and athletic performance in a partly positive way but does not influence blood glucose and growth hormone. 본 연구는 성장기 양궁선수들을 대상으로 1일 완전 수면 소실과 카페인 섭취 유․무에 따른 혈중글루코스와 성장호르몬이 경기력에 미치는 영향에 대하여 규명하고자 하는데 목적이 있다. 연구대상으로는 중학교 남자 양궁선수 6명을 대상으로 동일집단 내 반복측정 방법을 적용하였고, 측정된 항목은 SPSS 20.0 통계 프로그램으로 분석 처리되었다. 30M 기록은 One-Way Repeated Measure ANOVA를 사용하여 분석하였고, 심박수, 글루코스, 성장호르몬은 Two-Way Repeated Measure ANOVA를 사용하여 분석하였다. 이러한 결과는 수면 소실과 카페인 섭취는 심박수 및 경기력에 일정부분 긍정적인 영향을 미치는 것으로 나타났다. 그리고 수면 소실과 카페인 섭취는 혈중 글루코스와 성장호르몬에는 영향을 미치지 않는 것으로 나타났다.
