Take-all of Wheat and Natural Disease Suppression: A Review
한국식물병리학회 The Plant Pathology Journal 11 Pages
한국식물병리학회 The Plant Pathology Journal 2013, 29권 2호 2 125-135 (11 pages)
In agro-ecosystems worldwide, some of the most important and devastating diseases are caused by soil-borne necrotrophic fungal pathogens, against which crop plants generally lack genetic resistance. However, plants have evolved approaches to protect themselves against pathogens by stimulating and supporting specific groups of beneficial microorganisms that have the ability to protect either by direct inhibition of the pathogen or by inducing resistance mechanisms in the plant. One of the best... -
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... -
Mutation in clpxoo4158 Reduces Virulence and Resistance to Oxidative Stress in Xanthomonas oryzae pv. oryzae KACC10859

hydrogen peroxide and to over-produce siderophores. Complementation of the mutant restored the mutation-related phenotypes. Expression of clpxoo4158, assessed by reverse-transcription realtime PCR and clp promoter activity, was significantly reduced in the rpfB, rpfF, rpfC, and rpfG mutants. These results suggest that the clp homolog, clpxoo4158, is involved in the control of virulence and resistance against oxidative stress, and that expression of the gene is controlled by RpfC and RpfG through... -
Screening of Rhizobacteria for Biological Control of Cucumber Root and Crown Rot Caused by Phytophthora drechsleri
한국식물병리학회 The Plant Pathology Journal 7 Pages
한국식물병리학회 The Plant Pathology Journal 2011, 27권 1호 12 78-84 (7 pages)
Antagonistic rhizobacteria, more specifically fluorescent pseudomonads and certain species of Bacillus, are known as biocontrol agents of fungal root diseases of agronomic crops. In this study, 144 bacteria were isolated from cucumber rhizosphere and screened as potential biological control agents against Phytophthora drechsleri, the causal agent of cucumber root rot, in vitro condition. Non-volatile compounds of 23 isolates showed noticeable inhibition zone (> 30%) against P. drechsleri,... -
장수풍뎅이 유충의 장내 미생물을 이용한 다양한 식물 균류병의 생물적 방제 및 생장촉진
김준영, 김병섭 한국식물병리학회 식물병연구 12 Pages

곤충은 장내에 서식하고 있는 미생물과 상호작용을 통해 공생하는 것으로 알려져 있으며, 이러한 공생자는 공진화를 통하여 극한 환경에서도 서식을 가능하게 한다. 이러한 관점에서 토양 속에서 부엽토와 식물 잔재를 먹고 사는 장수풍뎅이 유충의장내에 존재하는 공생자는 식물병원균을 방제하는 데 유용한미생물이 존재할 것으로 생각된다. 따라서, 식물병원균에 대해활성을 갖는 유용 미생물 10종을 장수풍뎅이 유충의 소화기관 전장, 중장, 후장으로부터 분리하였다. 분리된 10종의 유용미생물은 유묘 검정을 통하여 토마토... -
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... -
Extracellular Polymeric Substances of Pseudomonas chlororaphis O6 Induce Systemic Drought Tolerance in Plants
Song Mi Cho, Anne J. Anderson, Young Cheol Kim 한국식물병리학회 식물병연구 6 Pages
한국식물병리학회 식물병연구 2018, 24권 3호 9 242-247 (6 pages)
Pseudomonas chlororaphis O6 induces systemic tolerance in plants against drought stress. A volatile, 2R, 3R-butanediol, produced by the bacterium causes partial stomatal closure, thus, limiting water loss from the plant. In this study, we report that applications of extracellular polymeric substances (EPS) from P. chlororaphis O6 to epidermal peels of leaves of Arabidopsis thaliana also reduce the size of stomatal openings. Growth of A. thaliana seedlings with applications of the EPS from P.... -

근권세균은 식물 생육과 건강 증진에 중요한 역할을 하며 생물학적 스트레스뿐만 아니라 저온, 고온, 건조 및 염과 같은 비생물적 스트레스에도 내성을 부여한다. 본 연구는 토마토에 생물적 및 비생물적 스트레스를 완화시키는 기능을 가진 식물 생장촉진 근권세균(plant growth promoting rhizobacteria, PGPR)을 선발하는 것을 목표로 하였으며 토마토 근권에서Variovorax sp. PMC12균주를 분리하였다. PMC12균주는 in vitro에서 PGPR의 특성으로 알려진 암모니아, IAA, 시드로포아 및 ACC 탈아민효소를 생성하였다. PMC12 균주를...
