NMMP1, a Matrix Metalloprotease in Nicotiana benthamiana Has a Role in Protection against Bacterial Infection
한국식물병리학회 The Plant Pathology Journal 7 Pages
한국식물병리학회 The Plant Pathology Journal 2010, 26권 4호 15 402-408 (7 pages)
Plant matrix metalloproteases (MMPs) are a family of apoplastic metalloproteases closely related to human matrilysins. Up-regulation of Nicotiana benthamiana matrix metalloprotease 1 (NMMP1) expression by treatment with pathogens, ethephon and aging indicates that the gene is related to plant defense and the aging process through ethylene signaling. NMMP1 expression was higher than in normal growth leaves following infection with an incompatible pathogen Pseudomonas syringae pv. tomato T1 or a... -
Functions of MAPK Cascade Pathways in Plant Defense Signaling
한국식물병리학회 The Plant Pathology Journal 9 Pages
한국식물병리학회 The Plant Pathology Journal 2010, 26권 2호 1 101-109 (9 pages)
cascade pathways play an important role in responses against biotic and abiotic stresses, including wounding, pathogen infection, temperature, drought, salinity and plant hormones. It is also known that MAPK cascadesmediated signaling is an essential process in the resistance step to pathogens by regulating the activity of transcription factors. Here, the insights into the functions of MAPK cascade pathways in plant defense response signaling from Arabidopsis, tobacco and rice are described. -
Roles of Plant Proteases in Pathogen Defense
한국식물병리학회 The Plant Pathology Journal 8 Pages
한국식물병리학회 The Plant Pathology Journal 2008, 24권 4호 1 367-374 (8 pages)
The genomes of plants contain more than 600 genes encoding a diverse set of proteases and the subunits of proteasomes. These proteases and proteasomes consist of plant proteolytic systems, which are involved in various cellular metabolic processes. Plant proteolytic systems have been shown to have diverse roles in defense responses, such as execution of the attack on the invading organisms, participation in signaling cascades, and perception of the invaders. In order to provide a framework for... -
Identification of Differentially Expressed Genes by cDNA-AFLP in Magnaporthe oryzae
Myoung-Hwan Chi, Sook-Young Park 한국식물병리학회 식물병연구 8 Pages
한국식물병리학회 식물병연구 2019, 25권 4호 7 205-212 (8 pages)
Analysis of differentially expressed genes has assisted discovery of gene sets involved in particular biological processes. The purpose of this study was to identify genes involved in appressorium formation in the rice blast fungus Magnaporthe oryzae via analysis of cDNA–amplified fragment length polymorphisms. Amplification of appressorial and vegetative mycelial cDNAs using 28 primer combinations generated over 200 differentially expressed transcript-derived fragments (TDFs). TDFs were... -

Altered expression of thioredoxin reductase-1 in dysplastic bile ducts and cholangiocarcinoma in a hamster model
Byung-IL Yoon, Dae-Yong Kim, Ja-June Jang, Jeong-Hee Han 대한수의학회 Journal of Veterinary Science 6 Pages
대한수의학회 Journal of Veterinary Science 2006, 제 7권 제 3호 1 211-216 (6 pages)
Thioredoxin reductase 1 (TrxR) is a homodimeric selenoenzyme catalyzing thioredoxin (Trx) in an NADPHdependent manner. With regard to carcinogenesis, these redox proteins have been implicated in cell proliferation, transformation and anti-apoptosis. In the present study, using a hamster cholangiocarcinoma (ChC) model, we evaluated the immunohistochemical expression pattern of TrxR in precancerous lesions and ChCs as well as in normal bile ducts. The goal of this study was to determine the... -
흰쥐 뇌 미토콘드리아에 의한 superoxide radical의 생성과 이 radical이 미토콘드리아 및 미토콘드리아 외 물질에 대한 독작용과 그 기전에 관한 연구

흰쥐 뇌 미토콘드리아에 의한 O2-⋅ 의 생성과 이 radical의 유해작용 및 그 작용기전을 알아보기 위하여 본실험을 수행하였다. Succinate와 antimycin존재하에서 미토콘드리아는 O2-⋅을 생성하였으며 이는 SOD-inhibitable NBT환원으로 확인되었다. 동일 조건에서 H2O2는 일차생성물인 O2-⋅의 dismutation으로 생성됨을 알수 있었다. 상기조건에서 미토콘드리아의 막지질이 파괴되었고 반응액에 첨가된 isocitrate dehydrogenase와 적혈구에 각각 불활성화와 용혈이 초래되었다. 이같은 작용은 Fe++이 있을때만 관찰... -
A Short-chain Dehydrogenase/reductase Gene is Required for Infection-related Development and Pathogenicity in Magnaporthe oryzae
한국식물병리학회 The Plant Pathology Journal 9 Pages
한국식물병리학회 The Plant Pathology Journal 2010, 26권 1호 2 8-16 (9 pages)
gene, MGG00056, which encodes a short-chain dehydrogenase/reductase (SDR). The mutant and annotated gene were designated as MoSDR1T-DNA and MoSDR1, respectively. Like other SDR family members, MoSDR1 possesses both a cofactor- binding motif and a catalytic site. The expression pattern of MoSDR1 suggests that the gene is associated with pathogenicity and plays an important role in M. oryzae development. To understand the roles of MoSDR1, the deletion mutant ΔMosdr1 for the gene was obtained via...
