Comparison of Bacterial Community of Healthy and Erwinia amylovora Infected Apples
Su-Hyeon Kim, Gyoengjun Cho, Su In Lee, Da-Ran Kim, Youn-Sig Kwak 한국식물병리학회 The Plant Pathology Journal 8 Pages
한국식물병리학회 The Plant Pathology Journal 2021, 37권 4호 9 396-403 (8 pages)
Fire blight disease, caused by Erwinia amylovora, could damage rosaceous plants such as apples, pears, and raspberries. In this study, we designed to understand how E. amylovora affected other bacterial communities on apple rhizosphere; twig and fruit endosphere; and leaf, and fruit episphere. Limited studies on the understanding of the microbial community of apples and changes the community structure by occurrence of the fire blight disease were conducted. As result of these experiments, the... -
Induction of Systemic Resistance against Bacterial Leaf Streak Disease and Growth Promotion in Rice Plant by Streptomyces shenzhenesis TKSC3 and Streptomyces sp. SS8
Erneeza Mohd Hata, Mohd Termizi Yusof, Dzarifah Zulperi 한국식물병리학회 The Plant Pathology Journal 9 Pages

The genus Streptomyces demonstrates enormous prom- ise in promoting plant growth and protecting plants against various pathogens. Single and consortium treat- ments of two selected Streptomyces strains (Streptomyces shenzhenensis TKSC3 and Streptomyces sp. SS8) were evaluated for their growth-promoting potential on rice, and biocontrol efficiency through induced systemic re- sistance (ISR) mediation against Xanthomonas oryzae pv. oryzicola (Xoc), the causal agent of rice bacterial leaf streak... -
Inhibitory Effect of Moriniafungin Produced by Setosphaeria rostrata F3736 on the Development of Rhizopus Rot
Min Young Park, So Jung Park, Jae-Jin Kim, Dong Ho Lee, Beom Seok Kim 한국식물병리학회 The Plant Pathology Journal 9 Pages
한국식물병리학회 The Plant Pathology Journal 2020, 36권 6호 4 570-578 (9 pages)
Rhizopus rot is a serious postharvest disease of various crops caused by Rhizopus spp. and controlled mainly by synthetic fungicides. We detected the antifungal activity of a culture extract of Setosphaeria rostrata F3736 against Rhizopus oryzae. The active ingredient was identified as moriniafungin, a known sordarin derivative, which showed minimum inhibitory concentrations of 1-8 μg/ml against Colletotrichum spp. and 0.03-0.13 μg/ml against Rhizopus spp. in vitro. Moriniafungin showed... -
Contribution of the murI Gene Encoding Glutamate Racemase in the Motility and Virulence of Ralstonia solanacearum
Kihyuck Choi, Geun Ju Son, Shabir Ahmad, Seung Yeup Lee, Hyoung Ju Lee, Seon-Woo Lee 한국식물병리학회 The Plant Pathology Journal 9 Pages

Bacterial traits for virulence of Ralstonia solanacearum causing lethal wilt in plants were extensively studied but are not yet fully understood. Other than the known virulence factors of Ralstonia solanacearum, this study aimed to identify the novel gene(s) contributing to bacterial virulence of R. solanacearum. Among the transposon-inserted mutants that were previously generated, we selected mutant SL341F12 strain produced exopolysaccharide equivalent to wild type strain but showed reduced... -
Roles of Fungal Volatiles from Perspective of Distinct Lifestyles in Filamentous Fungi
Mohamed El-Agamy Farh, Junhyun Jeon 한국식물병리학회 The Plant Pathology Journal 11 Pages

Volatile compounds (VOCs) are not only media for communication within a species but also effective tools for sender to manipulate behavior and physiology of receiver species. Although the influence of VOCs on the interactions among organisms is evident, types of VOCs and specific mechanisms through which VOCs work during such interactions are only beginning to become clear. Here, we review the fungal volatile compounds (FVOCs) and their impacts on different recipient or- ganisms from perspective... -
Comparison of Microbial Community of Rhizosphere and Endosphere in Kiwifruit
Min-Jung Kim, Heeil Do, Gyeongjun Cho, Rae-Dong Jeong, Youn-Sig Kwak 한국식물병리학회 The Plant Pathology Journal 7 Pages
한국식물병리학회 The Plant Pathology Journal 2019, 35권 6호 17 705-711 (7 pages)
Understanding the microbial community and function are crucial knowledge for crop management. In this study, bacterial and fungal community structures both rhizosphere and endosphere in kiwifruit were analyzed to gain our knowledge in kiwifruit microbiome. Microbial community in rhizosphere was less variation than endosphere community. Functional prediction results demonstrated that abundance of saprotrophic fungi was similar in both rhizosphere and endosphere, but potential pathogenic fungi was... -
Culturing Simpler and Bacterial Wilt Suppressive Microbial Communities from Tomato Rhizosphere
Nazish Roy, Kihyuck Choi, Raees Khan, Seon-Woo Lee 한국식물병리학회 The Plant Pathology Journal 13 Pages
한국식물병리학회 The Plant Pathology Journal 2019, 35권 4호 8 362-374 (13 pages)
Plant phenotype is affected by a community of associated microorganisms which requires dissection of the functional fraction. In this study, we aimed to culture the functionally active fraction of an upland soil microbiome, which can suppress tomato bacterial wilt. The microbiome fraction (MF) from the rhizosphere of Hawaii 7996 treated with an upland soil or forest soil MF was successively cultured in a designed modified M9 (MM9) medium partially mimicking the nutrient composition of tomato... -
Molecular Identification and Evaluation of Indigenous Bacterial Isolates for Their Plant Growth Promoting and Biological Control Activities against Fusarium Wilt Pathogen of Tomato

In search of an effective biological control agent against the tomato pathogen Fusarium oxysporum f. sp. lycopersici, rhizospheric soil samples were collected from eight agro-ecological zones of Bangladesh. Among the bacteria isolated from soil, 24 isolates were randomly selected and evaluated for their antagonistic activity against F. oxysporum f. sp. lycopersici. The two promising antagonistic isolates were identified as Brevundimonas olei and Bacillus methylotrophicus based on morphological,...
