본 연구는 소양강댐 하류에서 서식하는 생태계교란 생물 종인 브라운송어와 그 먹이원으로 이용되는 저서성 대형무척추동물에 대한 파악을 위해 2022년부터 2023년까지 총 8회에 걸쳐 소양강댐 하류(St.1~St.3)와 지류 (St.4)에 대해 브라운송어와 공서종, 브라운송어의 위 내용물, 저서성 대형무척추동물의 종조성 및 기능군 분석을 실시하였다. 저서성 대형무척추동물의 경우, 하루살이목에서 가장 많은 분류군이 확인되었으며(27.1%), 그 중 붙는 무리(CL)와 헤엄치는 무리(SW)가 높은 비율을 차지하는 것으로 확인되었다. 브라운송어 채집 결과, 전장은 26∼246mm까지 총 105개체가 채집되었으며, 전장-체중 관계의 매개변수 b값이 3을 초과하여 안정적인 성장이 이루어지는 것으로 확인되었다. 브라운송어의 위 내용물에 대한 먹이원 분석 결과, 빙어(0.2%, TL: 246mm)와 육상곤충(2.7%, TL: 154mm, 183∼185mm)을 섭식한 개체는 매우 적었으며 상대적으로 전장이 큰 개체에서 확인 되었다. 대부분 수서곤충(73.8%)과 물 속에서 서식하는 비곤충류(23.3%)를 섭식하는 것으로 나타났다. 브라운 송어의 전장에 따른 먹이 섭식 패턴을 파악하기 위해 위 내용물에서 확인된 종들과의 상관분석을 실시한 결과, 브라운송어의 먹이원 중 유수성 환경 선호 종들의 경우 전장과 양의 상관관계(p<0.05)를 나타낸 반면, 모래 기질 이하의 흐름이 적은 서식처를 선호하는 종들의 경우 전장과 음의 상관관계(p<0.05)를 나타냈다.

The serious emergence of chemical-mediated residual toxicity and insect resistance have been enforced the regulation of synthetic pesticides. Future decisions to select more realistic control options probably depend on the speed of technological development in chemical and biological pesticides. Now, a strategic collaboration between synthetic pesticides and biopesticides has been progressed, such as distribution and R&D in collaboration and M&A for obtaining microbial resources. Recently registered microbial pesticides are entomopathogenic fungi in pest management. A concept of e-biopesticide could be properly combined with digital agriculture and accelerate the use of biological control agents in the future farming.

In porcine production, porcine litter size is a quantitative trait and its heritability is especially low. So it is necessary to identify porcine reproductive gene and protein. The establishment of pregnancy requires performance of a receptive endometrium and ovary. The endometrium and ovary go through transformations in response to physiological changes initiated by local factors including ovarian hormones and uterine environment that make it for possible pregnancy. The endometrium and ovary secrete a wide array of growth factors, cytokines and proteins. Based on these background, we analyzed the endometrial tissue protein of porcine and would find out biomarker proteins related to porcine litter size. We sorted the two groups according to litter size of porcine: a small litter size group (SLSG) (n=2) and a large litter size group (LLSG) (n=2). The porcine endometrial tissue and ovary samples were preprocessed for proteomic analysis. In order to comparison, samples of each 2mg endometrium protein and ovary protein were separated form pI and molecular weight in the same conditions by applying a pH 3.0-10.0 IPG gels for the first dimension and then 8-16% SDS-PAGE gel for the second dimension. After proteins were visualized by staining with Commassie brilliant blue (CBB), image analysis was performed with Image Master detect variations in protein spots between large litter size group and small litter size group endometrium. And then differential proteins were identified using MALDI-TOF analysis. The master images of 2-DE gel images obtained from 2mg samples of large litter size group and small litter size group endometrial proteins at pH 3.0-10.0 revealed more than 400 protein spots in pH 3.0-10.0 range. When we analyzed the levels of expression of proteins that protein spots appeared more than 1.5-fold difference in endometrial tissue from porcine. In comparison of SLSG(small litter size group) with LLSG(large litter size group), a total of 18 protein spots differentially expressed on porcine endometrial tissue 2-DE gels, among which 9 spots were up-regulated proteins as retinol dehydrogenase 16-like isoform 1, Acrosin-binding protein, alpha-N-acetylgalactosaminidase. phosphoglycerate kinase 2, Acrosin-binding protein in LLSG. And 8 spots were up-regulated proteins as phosphoglycerate kinase 2, prenylcysteine oxidase in SLSG.

Little consideration has been given to the insect epizootiology in pest management. High production cost of fungalinsecticides might be a technical barrier. Application of the fungal insecticides to unfavorable conditions might result inlower performance in pest management. Herein this work, we suggest ecological biocontrol considering long-term colonizationin nature rather than quick pest control. Fungal biopesticides should be frequently combined with chemical pesticides infields, particualrly spatial combination strategy rather than temporal combination. Additionally other important technicalaspects need to be strongly considered, such as economic downstream process, effective control and environmentally safe,so finally proposing e-biopesticide. Lastly R&D system needs to be clearly and efficiently organized for high performance.Week-based summary and reporting system, weekly report and project file are main system in our laboratory which hasour lab work more effectively and efficiently, consequently resulting in tech-transfer to an industry and re-investment.

To identify subspecies and stocks of minke whale meats purchased from Korean markets during 2005-2007, we first obtained their complete sequences of mitochondrial DNA cytochrome b and control region sequences, and compared these sequences to the corresponding sequences of the common minke whale (Balaenoptera acutorostrata), obtained from GenBank. From analyses with partial cytochrome b sequences (383 bp) and non-coding, partial control region sequences (463 bp), Korean mink whale meats are identified as products from the North Pacific minke whale (B. a. scammoni). In addition, the sequences of the partial control region from these meats showed G at site no. 298 and G or A at site no. 463, and the meats appeared to originate from the J stock within this subspecies. Thus, because the J stock has been protected since 1986, implementation of strict regulation measures to reduce their accidental fisheries by catch seems urgent. In addition, B. a. scammoni is distinct from B. a. acutorostrata, with an average Jukes-Cantor distance of 2.21% in the complete control region sequence analysis (935 bp) and 1.31% in the complete cytochrome b gene sequence analysis; the current results support the current subspecies classification, although further sequencing analyses with nuclear genes are necessary.

Antioxidant activity is important for reducing oxidative stress that causes various metabolic disorders. Metabolic disorders are highly related to loss of productivity in livestock. Therefore, development of effective antioxidant compounds originating from plants is important for organic agriculture. Phenolic compounds in edible plants are regarded as major components relevant to antioxidant activity. The present study investigated the changes in antioxidant activity and phenolic compound profiles of Aronia (Aronia meloncarpa) by fermentation using different strains of Leuconostoc mesenteroides. A total of 5 strains of L. mesenteroides were used as starter cultures and their β-glucosidase activities were measured. A total of 6 experiment runs were prepared, one for control (uninoculated) and the others (inoculated) for treatments. For biological activity, antioxidant and antibacterial activities were measured. For phenolic compound profiling, TLC and HPLC analysis were performed. The strains of KACC12313 and KACC12315 showed greater enzyme activity than others. Treatment with KCCM35046 showed strong and broad antibacterial activity against to Listeria monocytogenes. Treatments with KCCM35046 and KACC12315 showed the highest total polyphenol content. The highest antioxidant activity was found in KACC12315 treatment. No remarkable alteration was found in thin layer chromatography (TLC) analysis. In phenolic compound profiling analysis, KCCM35046 showed notable alteration in compound area ratio compared to others and also showed the highest caffeic acid content. In chlorogenic acid, treatments with KCCM35046 and KACC12315 showed great content than others. Treatment with KACC12315 showed the greatest content of trans-ferulic acid. As a result of relative performance indexing analysis, L. mesenteroides KCCM35046 and KACC12315 were selected as the best strain for the fermentation of Aronia.

Mungbean (Vigna radiata) is a fast-growing, warm-season legume crop that is primarily cultivated in developing countries of Asia. We constructed a draft genome sequence of mungbean to facilitate genome research into the subgenus Ceratotropis and to enable a better understanding of the evolution of leguminous species. The draft genome sequence covers 80% of the estimated genome, of which 50.1% consists of repetitive sequences. In total, 22,427 high confidence protein-coding genes were predicted. Based on the de novo assembly of additional wild mungbean species, the divergence of what was eventually domesticated and the sampled wild mungbean species appears to have predated domestication. Moreover, the de novo assembly of a tetraploid Vigna species (Vigna reflexo-pilosa var. glabra) provided genomic evidence of a recent allopolyploid event. To further study speciation, we compared de novo RNA-seq assemblies of 22 accessions of 18 Vigna species and protein sets of Glycine max and Cajanus cajan. The species tree was constructed by a Bayesian Markov chain Monte Carlo method using highly confident orthologs shared by all 24 accessions. The present assembly of V. radiata var. radiata will facilitate genome research and accelerate molecular breeding of the subgenus Ceratotropis.
