Visualization of Phytophthora palmivora Infection in Oil Palm Leaflets with Fluorescent Proteins and Cell Viability Markers
Juan C. Ochoa, Mariana Herrera, M?nica Navia, Hern?n Mauricio Romero 한국식물병리학회 The Plant Pathology Journal 13 Pages
한국식물병리학회 The Plant Pathology Journal 2019, 35권 1호 3 19-31 (13 pages)
Bud rot (BR) is the most devastating disease affecting oil palm (Elaeis guineensis) crops in Colombia. Its causal agent, Phytophthora palmivora, initiates the infection in immature oil palm leaflets producing necrotic lesions, followed by colonization of opportunistic necrotrophs, which increases disease damage. To improve the characterization of the disease, we transformed P. palmivora using Agrobacterium tumefaciens-mediated transformation (ATMT) to include the fluorescent proteins CFPSKL... -
A Small GTPase RHO2 Plays an Important Role in Pre-infection Development in the Rice Blast Pathogen Magnaporthe oryzae
Teng Fu, Joon-Oh Kim, Joon-Hee Han, Adiyantara Gumilang, Yong-Hwan Lee, Kyoung Su Kim 한국식물병리학회 The Plant Pathology Journal 10 Pages
한국식물병리학회 The Plant Pathology Journal 2018, 34권 6호 2 470-479 (10 pages)
The rice blast pathogen Magnaporthe oryzae is a global threat to rice production. Here we characterized RHO2 gene (MGG_02457) that belongs to the Rho GTPase family, using a deletion mutant. This mutant ΔMorho2 exhibited no defects in conidiation and germination but developed only 6% of appressoria in response to a hydrophobic surface when compared to the wild-type progenitor. This result indicates that MoRHO2 plays a role in appressorium development. Furthermore, exogenous cAMP treatment on the... -
Comparative Analyses of Tomato yellow leaf curl virus C4 Protein-Interacting Host Proteins in Healthy and Infected Tomato Tissues
한국식물병리학회 The Plant Pathology Journal 11 Pages
한국식물병리학회 The Plant Pathology Journal 2016, 32권 5호 1 377-387 (11 pages)
Tomato yellow leaf curl virus (TYLCV), a member of the genus Begomovirus, is one of the most important viruses of cultivated tomatoes worldwide, mainly causing yellowing and curling of leaves with stunting in plants. TYLCV causes severe problems in sub-tropical and tropical countries, as well as in Korea. However, the mechanism of TYLCV infection remains unclear, although the function of each viral component has been identified. TYLCV C4 codes for a small protein involved in various cellular... -
Multi-Homologous Recombination-Based Gene Manipulation in the Rice Pathogen Fusarium fujikuroi
한국식물병리학회 The Plant Pathology Journal 9 Pages
한국식물병리학회 The Plant Pathology Journal 2016, 32권 3호 1 173-181 (9 pages)
Gene disruption by homologous recombination is widely used to investigate and analyze the function of genes in Fusarium fujikuroi, a fungus that causes bakanae disease and root rot symptoms in rice. To generate gene deletion constructs, the use of conventional cloning methods, which rely on restriction enzymes and ligases, has had limited success due to a lack of unique restriction enzyme sites. Although strategies that avoid the use of restriction enzymes have been employed to overcome this... -
Identification of a Gene Encoding Adenylate Kinase Involved in Antifungal Activity Expression of the Biocontrol Strain Burkholderia pyrrocinia CH-67
한국식물병리학회 The Plant Pathology Journal 8 Pages
한국식물병리학회 The Plant Pathology Journal 2012, 28권 4호 4 373-380 (8 pages)
Burkholderia pyrrocinia CH-67 is a biocontrol bacterium with strong antifungal activity against several plant pathogenic fungi. Transposon mutagenesis was performed to identify the genes responsible for the antifungal activity of B. pyrrocinia CH-67. Of the 2,500 mutants tested using the Fulvia fulva spore screening method, a mutant deficient in antifungal activity, M208, was selected. DNA sequence analysis of the transposon-inserted region revealed that a gene encoding an adenylate... -
Spatial and Temporal Distribution of a Biocontrol Bacterium Bacillus licheniformis N1 on the Strawberry Plants
한국식물병리학회 The Plant Pathology Journal 7 Pages
한국식물병리학회 The Plant Pathology Journal 2010, 26권 3호 5 238-244 (7 pages)
Spatial and temporal distribution of Bacillus licheniformis N1 was investigated over time on the leaves, petioles and crowns of the strawberry plants. Bacterial population on the strawberry plants was quantified over time by selective plating. Bacterial population of N1 containing a plasmid pWH43G carrying green fluorescent protein (GFP) declined relatively faster on the plant surface as compared to the Strain N1 itself. However, this result was found to be enough to utilize the strain to... -
Development of Recombinant Coat Protein Antibody Based IC-RT-PCR and Comparison of its Sensitivity with Other Immunoassays for the Detection of Papaya Ringspot Virus Isolates from India
한국식물병리학회 The Plant Pathology Journal 7 Pages
한국식물병리학회 The Plant Pathology Journal 2010, 26권 1호 4 25-31 (7 pages)
Papaya ringspot virus (PRSV) causes the most widespread and devastating disease in papaya. Isolates of PRSV originating from different geographical regions in south India were collected and maintained on natural host papaya. The entire coat protein (CP) gene of Papaya ringspot virus-P biotype (PRSV-P) was amplified by RTPCR. The amplicon was inserted into pGEM-T vector, sequenced and sub cloned into a bacterial expression vector pRSET-A using a directional cloning strategy. The PRSV coat protein... -
Transgenic Rice Plants Expressing an Active Tobacco Mitogen-activated Protein Kinase Kinase Induce Multiple Defense Responses
한국식물병리학회 The Plant Pathology Journal 9 Pages
한국식물병리학회 The Plant Pathology Journal 2008, 24권 4호 2 375-383 (9 pages)
It is well known that NtMEK2, a tobacco MAPK kinase, is the upstream kinase of both salicylic acidinduced protein kinase and wound-induced protein kinase. In addition, expression of NtMEK2DD, a constitutively active mutant of NtMEK2, is known to induce multiple defense responses in tobacco. In this study, transgenic rice plants that contained an active or inactive mutant of NtMEK2 under the control of a steroid inducible promoter were generated and used to determine if a similar MAPK cascade is... -

인문사회과학기술융합학회 예술인문사회융합멀티미디어논문지 2018, 제 8권 제 9호 85 863-871 (9 pages)
본 논문에서는 남녀 음성 분석을 이용하여 음주 전후의 음성특징을 비교하면서 음주여부를 판단할 수 있는 파라미터를 연구하였다. 기존에 제안된 방법은 변화하는 있는 운율, 발성상태 같은 특징을 정확하게 추출하고 분류하여 음주판단여부을 진행하였다. 또 다른 방법으로 음주 전후 포만트의 기울기 값을 이용하여 음주 여부를 판단할 수 있다. 포만트 기울기를 통한 음주판단방법은 대표적은 주파수 스펙트럼 형태를 근본으로한 음주판단방법이며 음주를 하기되면 음성신호의 주파수 스펙트럼 형태가 비음화 현상으로 인해 고주파...
