MoJMJ1, Encoding a Histone Demethylase Containing JmjC Domain, Is Required for Pathogenic Development of the Rice Blast Fungus, Magnaporthe oryzae
한국식물병리학회 The Plant Pathology Journal 13 Pages
한국식물병리학회 The Plant Pathology Journal 2017, 33권 2호 11 193-205 (13 pages)
Histone methylation plays important roles in regulating chromatin dynamics and transcription in eukaryotes. Implication of histone modifications in fungal pathogenesis is, however, beginning to emerge. Here, we report identification and functional analysis of a putative JmjC-domain-containing histone demethylase in Magnaporthe oryzae. Through bioinformatics analysis, we identified seven genes, which encode putative histone demethylases containing JmjC domain. Deletion of one gene, MoJMJ1,... -
Development of a Multiplex PCR Method to Detect Fungal Pathogens for Quarantine on Exported Cacti
한국식물병리학회 The Plant Pathology Journal 5 Pages
한국식물병리학회 The Plant Pathology Journal 2016, 32권 1호 7 53-57 (5 pages)
Major diseases in grafted cacti have been reported and Fusarium oxysporum, Bipolaris cactivora, Phytophthora spp. and Collectotrichum spp. are known as causal pathogens. These pathogens can lead to plant death after infection. Therefore, some European countries have quarantined imported cacti that are infected with specific fungal pathogens. Consequently, we developed PCR detection methods to identify four quarantined fungal pathogens and reduce export rejection rates of Korean grafted cacti.... -
Effect of Aerated Compost Tea on the Growth Promotion of Lettuce, Soybean, and Sweet Corn in Organic Cultivation
한국식물병리학회 The Plant Pathology Journal 10 Pages
한국식물병리학회 The Plant Pathology Journal 2015, 31권 3호 7 259-268 (10 pages)
This study investigated the chemical characteristics and microbial population during incubation of four kinds of aerated compost teas based on oriental medicinal herbs compost, vermicompost, rice straw compost, and mixtures of three composts (MOVR). It aimed to determine the effects of the aerated compost tea (ACT) based on MOVR on the growth promotion of red leaf lettuce, soybean and sweet corn. Findings showed that the pH level and EC of the compost tea slightly increased based on the... -
Analysis of in planta Expressed Orphan Genes in the Rice Blast Fungus Magnaporthe oryzae
한국식물병리학회 The Plant Pathology Journal 8 Pages
한국식물병리학회 The Plant Pathology Journal 2014, 30권 4호 4 367-374 (8 pages)
Genomes contain a large number of unique genes which have not been found in other species. Although the origin of such “orphan” genes remains unclear, they are thought to be involved in species-specific adaptive processes. Here, we analyzed seven orphan genes (MoSPC1 to MoSPC7) prioritized based on in planta expressed sequence tag data in the rice blast fungus, Magnaporthe oryzae. Expression analysis using qRT-PCR confirmed the expression of four genes (MoSPC1, MoSPC2, MoSPC3 and MoSPC7)... -
Roles of Forkhead-box Transcription Factors in Controlling Development, Pathogenicity, and Stress Response in Magnaporthe oryzae
한국식물병리학회 The Plant Pathology Journal 15 Pages
한국식물병리학회 The Plant Pathology Journal 2014, 30권 2호 4 136-150 (15 pages)
Although multiple transcription factors (TFs) have been characterized via mutagenesis to understand their roles in controlling pathogenicity and infection-related development in Magnaporthe oryzae, the causal agent of rice blast, if and how forkhead-box (FOX) TFs contribute to these processes remain to be characterized. Four putative FOX TF genes were identified in the genome of M. oryzae, and phylogenetic analysis suggested that two of them (MoFKH1 and MoHCM1) correspond to Ascomycota-specific... -
Biocontrol of Late Blight (Phytophthora capsici) Disease and Growth Promotion of Pepper by Burkholderia cepacia MPC-7
한국식물병리학회 The Plant Pathology Journal 10 Pages
한국식물병리학회 The Plant Pathology Journal 2013, 29권 1호 8 67-76 (10 pages)
A chitinolytic bacterial strain having strong antifungal activity was isolated and identified as Burkholderia cepacia MPC-7 based on 16S rRNA gene analysis. MPC- 7 solubilized insoluble phosphorous in hydroxyapatite agar media. It produced gluconic acid and 2-ketogluconic acid related to the decrease in pH of broth culture. The antagonist produced benzoic acid (BA) and phenylacetic acid (PA). The authentic compounds, BA and PA, showed a broad spectrum of antimicrobial activity against yeast,... -
Suppression of UDP-glycosyltransferase-coding Arabidopsis thaliana UGT74E2 Gene Expression Leads to Increased Resistance to Psuedomonas syringae pv. tomato DC3000 Infection
한국식물병리학회 The Plant Pathology Journal 13 Pages
한국식물병리학회 The Plant Pathology Journal 2011, 27권 2호 10 170-182 (13 pages)
Plants possess multiple resistance mechanisms that protect themselves against pathogen attack. To identify unknown components of the defense machinery in Arabidopsis, gene-expression changes were monitored in Arabidopsis thaliana under 18 different biotic or abiotic conditions using a DNA microarray representing approximately 25% of all Arabidopsis thaliana genes (www.genevestigator.com). Seventeen genes which are early responsive to salicylic acid (SA) treatment as well as pathogen infection... -
Genetic Stability of Magnaporthe oryzae during Successive Passages through Rice Plants and on Artificial Medium
한국식물병리학회 The Plant Pathology Journal 8 Pages
한국식물병리학회 The Plant Pathology Journal 2010, 26권 4호 3 313-320 (8 pages)
Genetic instability of the rice blast fungus Magnaporthe oryzae has been suggested as a major factor underlying the rapid breakdown of host resistance in the field. However, little information is available on the mechanism of genetic instability. In this study, we assessed the stability of repetitive DNA elements and several key phenotypic traits important for pathogenesis after serially transferring two isolates though rice plants and an artificial medium. Using isolate 70-15, we obtained a... -
Production of Surfactin and Iturin by Bacillus licheniformis N1 Responsible for Plant Disease Control Activity
한국식물병리학회 The Plant Pathology Journal 8 Pages
한국식물병리학회 The Plant Pathology Journal 2010, 26권 2호 10 170-177 (8 pages)
Bacillus licheniformis N1, previously developed as a biofungicide formulation N1E to control gray mold disease of plants, was investigated to study the bacterial traits that may be involved in its biological control activity. Two N1E based formulations, bacterial cell based formulation PN1E and culture supernatant based formulation SN1E, were evaluated for disease control activity against gray mold disease of tomato and strawberry plants. Neither PN1E nor SN1E was as effective as the original... -
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)
The phytopathogenic fungus Magnaporthe oryzae is a major limiting factor in rice production. To understand the genetic basis of M. oryzae pathogenic development, we previously analyzed a library of T-DNA insertional mutants of M. oryzae, and identified ATMT0879A1 as one of the pathogenicity-defective mutants. Molecular analyses and database searches revealed that a single TDNA insertion in ATMT0879A1 resulted in functional interference with an annotated gene, MGG00056, which encodes a...
