the control. The composition and structure of the bacterial communities varied with soil salinity levels, and those in the H20-5 treated rhizosphere soil were clustered. The members of Actinobacteria genera, including Kineosporia, Virgi- sporangium, Actinoplanes, Gaiella, Blastococcus, and Solirubrobacter, were enriched in the H20-5 treated rhizosphere soils. The microbial co-occurrence network of the bacterial community in the H20-5 treated rhizosphere soils had more modules and keystone taxa... -

Brown leaf spot disease caused by Nigrospora guilin- ensis on Phellodendron chinense occurs in a large area in Dayi County, Chengdu City, Sichuan Province, China each year. This outbreak has severely reduced the production of Chinese medicinal plants P. chinense and caused substantial economic losses. The bacterial isolate JKB05 was isolated from the healthy leaves of P. chinense, exhibited antagonistic effects against N. guilinensis and was identified as Bacillus megaterium. The following... -

Nutrient manipulation is a promising strategy for controlling plant diseases in sustainable agriculture. Although many studies have investigated the relationships between certain elements and plant diseases, few have comprehensively explored how differing mineral nutrition levels might affect plant–fungal pathogen interactions, namely plant susceptibility and resistance. Here, we systematically explored the effects of the seven mineral elements that plants require in the greatest amounts... -

한국식물병리학회 The Plant Pathology Journal 2020, 36권 2호 5 157-169 (13 pages)
Two lactic acid bacteria (LAB) designated J02 and J13 were recovered from fermented vegetables based on their ability to suppress soft rot disease caused by Pectobacterium carotovorum subsp. carotovorum (Pcc) on radish. J02 and J13 were identified as Lactobacillus pentosus and Leuconostoc fallax, respectively. The abil- ity of J02 and J13 to suppress plant diseases is highly dependent on chitosan. LAB alone has no effect and chitosan alone has only a moderate effect on disease reduction.... -

To investigate the difference in the disinfectant efficiency of ozone microbubbles (O3MB) and ozone millibubbles (O3MMB), the morphological change of the treated Fusarium oxysporum f. sp. melonis spores was observed with scanning and transmission electron microscopies (SEM and TEM). The disinfectant efficiency of O3MB on F. oxysporum f. sp. melonis spores was greater than that of O3MMB. On observation with SEM, it was revealed that morphological change of F. oxysporum f. sp. melonis spores was... -

한국식물병리학회 The Plant Pathology Journal 2018, 34권 4호 3 286-296 (11 pages)
genes involved in nitrogen cycling were upregulated by JBLS202 treatment indicating changes in ecological function of the rhizosphere soil. Overall, these results indicate that introduction of JBLS202 alters both the composition and function of the rhizosphere bacterial community, which can have direct and indirect effects on plant growth. Therefore, we propose that long-term changes in bacterial composition and community-level function need to be considered for practical use of PGPRs. -

had the most effective concentration on growth parameters in foliage part. However, 0.8% MOVR significantly promoted the growth of root and shoot of both soybean and sweet corn. The soybean treated with higher MOVR concentration was more effective in increasing the root nodule formation by 7.25 times than in the lower MOVR concentrations Results indicated that ACT could be used as liquid nutrient fertilizer with active microorganisms for culture of variable crops under organic farming condition. -
Antifungal Activity of a Synthetic Cationic Peptide against the Plant Pathogens Colletotrichum graminicola and Three Fusarium Species
한국식물병리학회 The Plant Pathology Journal 6 Pages
한국식물병리학회 The Plant Pathology Journal 2015, 31권 3호 14 316-321 (6 pages)
A small cationic peptide (JH8944) was tested for activity against a number of pathogens of agricultural crops. JH8944 inhibited conidium growth in most of the tested plant pathogens with a dose of 50 μg/ml, although one isolate of Fusarium oxysporum was inhibited at 5 μg/ml of JH8944. Most conidia of Fusarium graminearum were killed within 6 hours of treatment with 50 μg/ml of JH8944. Germinating F. graminearum conidia required 238 μg/ml of JH8944 for 90% growth inhibition. The peptide did... -
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... -

유기농업은 지속가능한 농업을 위해서 필요하며, 생물 다양성 유지를 위해 필수적인 경작 방법으로 전 세계적으로 성장하고 있는 농업 분야 중 하나이다. 유기농업은 인류의 건강과 환경에 유해한 영향을 끼질 수 있는 화학적 제재의 사용을 줄이고, 친환경적 동·식물성 비료, 식물 추출물, 미생물 제재 등이사용되기 때문에 소비자에게 안전한 농산물을 제공할 수 있다. 노지 고추를 대상으로 3년간 유기농업 환경과 관행농업 환경에서 주요 병해 발생과 토양 미생물상의 조사하였다. 토양 미생물상의 차이는 차세대 염기서열 분석... -
Phytobiome as a Potential Factor in Nitrogen-Induced Susceptibility to the Rice Blast Disease
Junhyun Jeon 한국식물병리학회 식물병연구 5 Pages
한국식물병리학회 식물병연구 2019, 25권 3호 1 103-107 (5 pages)
Roles of nutrients in controlling plant diseases have been documented for a long time. Among the nutrients having impact on susceptibility/resistance to crop diseases, nitrogen is one of the most important nutrients for plant growth and development. In rice plants, excess nitrogen via fertilization in agricultural systems is known to increase susceptibility to the rice blast disease. Mechanisms underlying such phenomenon, despite its implication in yield and sustainable agriculture, have not... -

한국탄소학회 Carbon Letters 2014, Vol.15 No.1 8 57-66 (10 pages)
Three activated carbons (ACs) were prepared using NaOH (N) as an activating agent. Hydrofluoric acid pre-leached rice husk was used as a precursor. After leaching, the precursor was washed with distilled water, dried, crushed, and then sieved; a size fraction of 0.3-0.5 mm was selected for carbonization in the absence of air at 600°C. The carbonization product (LC) was mixed with NaOH at ratios of 1:2, 1:3, and 1:4 (wt of LC: wt of NaOH) and the produced ACs after activation at 800°C were... -

A small irrigation pond for a rice paddy field is a very important refuge for aquatic insects and plants. To reveal environmental factors determining species composition of aquatic insect and plant communities, we analyzed water chemistry and connection between pond and surrounding in five types of irrigation ponds based on water source and connection in CCZ of South Korea: stagnation, exchange-stagnation, spring, stagnation-spring, and exchangespring types. The stagnation type had the most... -

인간은 생태계로부터 다양한 공익적 기능을 제공받고 있지만 시설원예단지 조성은 불투수면적 확장과 생물서식처 손 실로 인해 기능저하의 원인이 될 수 있다. 시설원예단지 조성이 식물 종 다양성에 미치는 영향을 파악하였다. 식생분포 특성 분석결과 논에 비해 시설원예단지의 식물다양성이 상당히 낮다는 것을 알 수 있었다. 따라서 저 영향개발, 서식공 간 배치, 식물 보전, 화학비료 사용제한, 서식처 조성, 보전비용 등을 제안하였다. 생활형 분석을 통해 일년생식물과 수 생식물의 생육기반 환경 조성을 제시하였다. 귀화식물은... -

한국습지학회 한국습지학회지 2012, Vol.14 No.3 5 365-374 (10 pages)
양돈 농가에서 구리, 아연 등의 성장촉진제와 항생제들이 사료 첨가제로 사용되는데 사료에 주입된 많은 양이 분뇨로 배설되고 있다. 국내 양돈 폐수의 90% 이상이 퇴, 액비 형태로 농지에 적용되고 있는 상황에서 퇴, 액비 내에 함유된 중금속과 항생물질은 토양에 흡착되어 농지에 잔류하거나 지하수나 지표수로 유출되어 수계로 빠져나간다. 농지에 살포된 중금속과 항생물질의 토양 내에서의 거동을 살펴보기 위해 실험실 기초 실험을 수행하였는데, Jar test와 칼럼 용출 실험을 수행하였다. 실험결과 아연의 86.4와 구리의 68%가... -
Nutrient dynamics in montane wetlands, emphasizing the relationship between cellulose decomposition and water chemistry
한국습지학회 한국습지학회지 2005, Vol.7 No.4 1 33-42 (10 pages)
Wetlands often function as a nutrient sink. It is well known that increased input of nutrient increases the primary productivity but it is not well understood what is the fate of produced biomass in wetland ecosystem. Water and sediment quality, decomposition rate of cellulose, and sediment accumulation rate in 11 montane marshes in northern Sierra Nevada, California were analyzed to trace the effect of nitrogen and phosphorus content in water on nutrient dynamics. Concentrations of ammonium,... -

Questioning is the key component to create curiosity, motivation, and critical thinking in the students. This study aimed at analysing and comparing the questioning strategies in the chemistry units of middle and high school science textbooks of Nepal and Korea. The TQSAI was used as the instrument for analysing the questions in middle and high school textbooks. The questions were classified as the experiential type or the non-experiential type. In general, the Nepalese textbooks consist of a...
