Changes in physiological and biochemical patterns in lucerne plants caused by the presence of ‘Candidatus Phytoplasma australasia’, which is one of the significant pathogens causing yield losses in lucerne plants, were investigated. Significant differences were evident in total chlorophyll, chlorophyll a, chlorophyll b, and protein amounts between ‘Ca. Phytoplasma australasia’- positive and negative lucerne plants. Stress-related metabolites such as phenol, malondialdehyde, and proline... -

Rice yellow mottle virus (RYMV) is the most harmful virus that affects irrigated and lowland rice in Africa. The RBe24 isolate of the virus is the most pathogenic strain in Benin. A total of 79 genotypes including sus- ceptible IR64 (Oryza sativa) and the resistant TOG5681 (O. glaberrima) as checks were screened for their reactions to RBe24 isolate of RYMV and the effects of silicon on the response of host plants to the virus inves- tigated. The experiment was a three-factor factorial consisting... -

SCYLV is the major limitation to sugarcane production worldwide and presently occurring in most of the sugarcane growing countries. SCYLV having high genetic diversity within the species and presently ten genotypes are known to occur based on the complete genome sequence information. SCYLV is present in almost all the states of India where sugarcane is grown. Virion comprises of 180 coat... -
The Shaker Type Potassium Channel, GORK, Regulates Abscisic Acid Signaling in Arabidopsis
Chae Woo Lim, Sang Hee Kim, Hyong Woo Choi, Sheng Luan, Sung Chul Lee 한국식물병리학회 The Plant Pathology Journal 8 Pages
한국식물병리학회 The Plant Pathology Journal 2019, 35권 6호 14 684-691 (8 pages)
Evolution of adaptive mechanisms to abiotic stress is essential for plant growth and development. Plants adapt to stress conditions by activating the abscisic acid (ABA) signaling pathway. It has been suggested that the ABA receptor, clade A protein phosphatase, SnRK2 type kinase, and SLAC1 anion channel are important components of the ABA signaling pathway. In this study, we report that the shaker type potassium (K+) channel, GORK, modulates plant responses to ABA and abiotic stresses. Our... -

Kiwifruit (Actinidia spp.) is an economically important crop and a bacterial canker disease, caused by Pseudomonas syringae pv. actinidiae (Psa), is the most destructive disease in kiwifruit production. Therefore, prevent and control of the disease is a critical issue in kiwifruit industry worldwide. Unfortunately, there is no reliable control methods have been developed. Recently, interest in disease control using microbial agents is growing. However, kiwifruit microbiota and their roles in the... -

한국식물병리학회 The Plant Pathology Journal 11 Pages
한국식물병리학회 The Plant Pathology Journal 2016, 32권 6호 3 508-518 (11 pages)
Early blight of tomato caused by Alternaria solani, is responsible for severe yield losses in tomato. The conidia survive on soil surface and old dry lower leaves of the plant and spread when suitable climatic conditions are available. Macroclimatic study reveals that highest inoculum concentration of Alternaria spores appeared in May 2012 to 2013 and lowest concentration during January 2012 to 2013. High night temperature positively correlated and significantly (P ; 0.01) involved in conidial... -

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. -

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... -

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... -

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.... -

기후변동에 따른 식생반응 및 그에 따른 물수지 동역학의 변화를 살펴볼 목적으로 본 연구에서는 식생의물 이용가능성과 식생 생산량의 지역별 연별 변동성을 분석하였다. 유역의 식생 물이용의 대리변수로서 습윤량에 대한 기화량의 비로 표현되는 Horton 지수의 계산을 통하여 유역에서의 수문 분할과 그에 따른 식생의 물 이용 가능성에 대한 정량화를 시도하였다. 연별 Horton 지수의 추정결과 기후의 변동성과 비교하여 볼 때 상대적으로 일정한 값을 유지하고 있는 것을 살펴볼 수 있다. 이와 더불어 Horton 지수와 식생의... -
Meta-Gaussian 방법을 이용한 강우-유출 모형에서의 불확실성 산정

홍수나 가뭄 등 극한 사상을 예측하여 재해에 대비하거나 또는 수자원을 효율적으로 관리, 배분하기 위하여 강우-유출 모형이 이용되고 있다. 그러나 많은 수문학자들은 강우-유출 모형이 가질 수밖에 없는 불확실성에대하여 언급하였다. 실제 유역에 내린 강우는 증발과 증산, 차단, 침투 등 여러 과정을 거쳐 유출로 이어지는데,모형에서는 이러한 복잡한 물리적 과정을 단순화하여 표현하였으므로 불확실성이 반드시 존재할 수밖에 없는 것이다. 따라서 모형으로부터의 모의 결과를 신뢰할 수 있는지를 정량적으로 판단하는 과정이... -

식물에서 수액 상승 원리에 대한 이해
이복선 공주교육대학교 초등교육연구원 교육논총 15 Pages
공주교육대학교 초등교육연구원 교육논총 52권1호 10 187-201 (15 pages)
식물체에서 수액상승의 원리는 근압설(양압)과 응집력설(음압)으로 설명되고 있다. 그러나 증산에 의 한 물기둥의 상승인 응집력-장력 가설에서 색전 현상을 회복하는 설명이 부족하였다. 오랫동안 단 순한 물리적인 현상으로 모세관 이론에 의해 표면장력과 증산으로 인한 곡면이 충분히 물기둥을 다 시 연결시킬 수 있다고 보았으나 이제는 새로운 관점으로 도관 유조직의 도움을 받아서 당을 분비 함으로 삼투적인 회복이 일어난다고 본다. 따라서 도관은 더 이상 죽은 조직이 아니라 살아 있는 조직으로 체관과의 상호작용을 하여... -

한국습지학회 한국습지학회지 2016, Vol.18 No.1 2 10-15 (6 pages)
In this research, the environmental effects of rain garden when applied to a stormwater runoff originated from a rooftop were evaluated. The rain garden that was utilized as LID represents less than 1% of the catchment area that it drains. Storm event monitoring was conducted from March 2012 to August 2014 on a total of 19 storm events. In the 19 storm events that was monitored only 32% produced an outflow which has a mean rainfall characteristic of approximately 25 mm. With the application of...
