3-Methylthiopropionic Acid of Rhizoctonia solani AG-3 and Its Role in the Pathogenicity of the Fungus
한국식물병리학회 The Plant Pathology Journal 10 Pages
한국식물병리학회 The Plant Pathology Journal 2016, 32권 2호 2 85-94 (10 pages)
Studies were conducted to determine the role of 3-methylthioproprionic acid (MTPA) in the pathogenicity of potato stem canker, Rhizoctonia solani, and the concentrations required to inhibit growth of R. solani under laboratory and plant house-based conditions. The experiments were laid out in a completely randomized design with five treatments and five replications. The treatments were 0, 1, 2, 4, and 8 mM concentrations of MTPA. The purified toxin exhibited maximal activity at pH 2.5 and... -
Systemic Infection of Maize, Sorghum, Rice, and Beet Seedlings with Fumonisin-Producing and Nonproducing Fusarium verticillioides Strains
한국식물병리학회 The Plant Pathology Journal 9 Pages
한국식물병리학회 The Plant Pathology Journal 2015, 31권 4호 2 334-342 (9 pages)
Two fumonisin-nonproducing strains of Fusarium verticillioides and their fumonisin producing progenitors were tested for aggressiveness toward maize, sorghum, rice, and beetroot seedlings grown under greenhouse conditions. None of the plants showed obvious disease symptoms after root dip inoculation. Fungal biomass was determined by species-specific real-time PCR. No significant (P = 0.05) differences in systemic colonization were detected between the wild type strains and mutants not producing... -
Note : Open Access ; Arabidopsis PYL8 Plays an Important Role for ABA Signaling and Drought Stress Responses
한국식물병리학회 The Plant Pathology Journal 6 Pages
한국식물병리학회 The Plant Pathology Journal 2013, 29권 4호 16 471-476 (6 pages)
seedling growth and establishment. We found that hypersensitivity to ABA of transgenic plants results in high degrees of stomatal closure in response to ABA leading to low transpiration rates and ultimately more vulnerable to drought than the wild-type plants. In addition, high expression of ABA maker genes also contributes to altered drought tolerance phenotype. Overall, this work emphasizes the importance of ABA signaling by ABA receptor in stomata during defense response to drought stress. -
Neofusicoccum ribis Associated with Leaf Blight on Rubber (Hevea brasiliensis) in Peninsular Malaysia
한국식물병리학회 The Plant Pathology Journal 7 Pages
한국식물병리학회 The Plant Pathology Journal 2013, 29권 1호 2 10-16 (7 pages)
Hevea brasiliensis is a natural source of rubber and an important plantation tree species in Malaysia. Leaf blight disease caused by Fusicoccum substantially reduces the growth and performance of H. brasiliensis. The aim of this study was to use a combination of both morphological characteristics and molecular data to clarify the taxonomic position of the fungus associated with leaf blight disease. Fusicoccum species were isolated from infected leaves collected from plantations at 3 widely... -
A Forecast Model for the First Occurrence of Phytophthora Blight on Chili Pepper after Overwintering
한국식물병리학회 The Plant Pathology Journal 13 Pages
한국식물병리학회 The Plant Pathology Journal 2012, 28권 2호 6 172-184 (13 pages)
An infection risk model for Phytophthora blight on chili pepper was developed to estimate the first date of disease occurrence in the field. The model consisted of three parts including estimation of zoosporangium formation, soil water content, and amount of active inoculum in soil. Daily weather data on air temperature, relative humidity and rainfall, and the soil texture data of local areas were used to estimate infection risk level that was quantified as the accumulated amount of active... -
농업기상 빅데이터를 활용한 스마트 식물병 관리
김광형, 이준혁 한국식물병리학회 식물병연구 13 Pages
한국식물병리학회 식물병연구 2020, 26권 3호 1 121-133 (13 pages)
기후변화와 이상기후, 급변하는 사회경제적 환경 하에 식량안보를 확보하고 지속가능한 성장을 위해서는 기존의 관행농업을 벗어나 빅데이터와 인공지능을 활용한 스마트농업으로의전환이 시급하다. 스마트농업을 통해 식물병을 효율적으로 관리하기 위해서는 다양한 첨단기술과 융합할 수 있는 농업 빅데이터가 우선 확보되어야 한다. 본 리뷰에서는 스마트식물병관리를 위해 식물병리학 분야에서 기여할 수 있는 기상환경 및 농업 빅데이터에 대해 알아보고 이를 활용한 식물병의 예측, 모니터링 및 진단, 방제, 예방 및 위험관리의 각... -
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.... -

기공은 식물의 생명 활동 유지에 필수적인 구조이다. 이에 대한 현미경 관찰 결과는 여러 선 행 연구에서 확인할 수 있다. 본 연구에서는 쉽게 기공 부위를 떼어낼 수 있는 네일 래커를 이 용한 방법으로 여러 종의 식물 기공을 준비한 후, 현장에서 활용 가능성이 높은 위상차 현미경 을 사용하여 여러 식물의 기공을 관찰하였다. 연구자는 초본과 목본의 기공 구조에서 차이가 있을 것으로 예상하였고, 식물의 서식지와 식물의 크기 차이에 따른 기공 구조의 차이가 있을 것으로 예상하였다. 그리고 이러한 차이를 이용하여 식물을... -
Simulation of Various Baffle Types in a Constructed Wetland Sedimentation Tank using CFD
Taegyun Noh, Jechan Jeon, Lee-Hyung Kim 한국습지학회 한국습지학회지 6 Pages
한국습지학회 한국습지학회지 2016, Vol.18 No.3 15 324-329 (6 pages)
Constructed wetlands are widely applied in urban and rural areas for various purposes such as pollutants reduction, acquisition of eco-spaces and habitats, flooding reduction, acquisition of water resources and environmental education. Since the design of constructed wetlands utilizes ecosystems, special consideration must be given to ecological mechanisms, environmental mechanisms and hydrological mechanisms. To ensure the sustainable functionality of constructed wetlands, it is necessary to... -

We obtained the following results from investigation on vegetation damage from 5 to 6 August, 2013, about one year after an accident that hydrofluoric acid leaked from a chemical maker, Hube Globe in Gumi. Pinus densiflora and Pinus strobus showed very severe damage. Ginko biloba, Quercus acutissima, Pinus rigida, Salix glandulosa, Hibiscus syriacus, and Lagerstroemia indica showed severe damage. Quercus variabilis, Lespedeza cyrtobotrya, and Miscanthus sinensis showed moderate damage. Quercus...
