Seoyeon Ko, Na-Kyeong Kim, Hyo-Jeong Lee, Tae-Ho Ryu, Jin-Sung Hong, Rae-Dong Jeong 한국식물병리학회 The Plant Pathology Journal 6 Pages
한국식물병리학회 The Plant Pathology Journal 2020, 36권 5호 13 503-508 (6 pages)
The potential transmission of plant pathogenic viruses through processed foods could be a source of concern for global crop production; however, there is a lack of supporting evidence. The present study was conducted to investigate the presence of plant pathogenic viruses in five samples of gochujang (fermented red pepper paste) manufactured in Korea. Several viruses infecting pepper were detected by reverse transcriptionpolymerase chain reaction, among which the pepper mild mottle virus (PMMoV)... -
Biological Control of Gom-chwi (Ligularia fischeri) Phytophthora Root Rot with Enterobacter asburiae ObRS-5 to Suppress Zoosporangia Formation and Zoospores Germination
Dayeon Kim, Sang Yeob Lee, Seong Ho Ahn, Ji Hee Han, Jin Woo Park 한국식물병리학회 The Plant Pathology Journal 11 Pages
한국식물병리학회 The Plant Pathology Journal 2020, 36권 3호 5 244-254 (11 pages)
Gom-chwi (Ligularia fischeri) is severely infected with Phytophthora drechsleri, the causal organism of Phy- tophthora root rot, an economically important crop disease that needs management throughout the cultiva- tion period. In the present study, Phytophthora root rot was controlled by using bacterial isolates from rhizo- sphere soils collected from various plants and screened for antagonistic activity against P. drechsleri. A total of 172 bacterial strains were isolated, of which, 49 strains... -
Simple Detection of Cochliobolus Fungal Pathogens in Maize
In Jeong Kang, Hyeong Kwon Shim, Jae Hwan Roh, Sunggi Heu, Dong Bum Shin 한국식물병리학회 The Plant Pathology Journal 8 Pages
한국식물병리학회 The Plant Pathology Journal 2018, 34권 4호 7 327-334 (8 pages)
Northern corn leaf spot and southern corn leaf blight caused by Cochliobolus carbonum (anamorph, Bipolaris zeicola) and Cochliobolus heterostrophus (anamorph, Bipolaris maydis), respectively, are common maize diseases in Korea. Accurate detection of plant pathogens is necessary for effective disease management. Based on the polyketide synthase gene (PKS) of Cochliobolus carbonum and the nonribosomal peptide synthetase gene (NRPS) of Cochliobolus heterostrophus, primer pairs were designed for PCR... -
Xanthomonas euvesicatoria Causes Bacterial Spot Disease on Pepper Plant in Korea
한국식물병리학회 The Plant Pathology Journal 10 Pages
한국식물병리학회 The Plant Pathology Journal 2016, 32권 5호 7 431-440 (10 pages)
In 2004, bacterial spot-causing xanthomonads (BSX) were reclassified into 4 species—Xanthomonas euvesicatoria, X. vesicatoria, X. perforans, and X. gardneri. Bacterial spot disease on pepper plant in Korea is known to be caused by both X. axonopodis pv. vesicatoria and X. vesicatoria. Here, we reidentified the pathogen causing bacterial spots on pepper plant based on the new classification. Accordingly, 72 pathogenic isolates were obtained from the lesions on pepper plants at 42... -
Research Notes : Molecular Evidence of Recombination on Korean Isolates of Tomato yellow Leaf curl virus by Nucleotide Transversions and Transitions
한국식물병리학회 The Plant Pathology Journal 7 Pages
한국식물병리학회 The Plant Pathology Journal 2011, 27권 4호 12 378-384 (7 pages)
Tomato yellow leaf curl virus (TYLCV), a member of genus Begomovirus, was isolated in Korea in 2008. We sequenced and analyzed the DNA-A of 51 TYLCV isolates from Korea, and 13 of the TYLCV isolates were selected as type representatives of TYLCV from six Korean provinces. The 13 TYLCV isolates were classified into Korea Group 1 (KG1, nine isolates) and Korea Group 2 (KG2, four isolates) based on the results of phylogenetic analysis and genome size (2774 and 2781 nucleotides, respectively). A... -

Effects of Temperature and Culture Media Composition on Sporulation, Mycelial Growth, and Antifungal Activity of Isaria javanica pf185
Jang Hoon Lee, Yong Seong Lee, Young Cheol Kim 한국식물병리학회 식물병연구 8 Pages
한국식물병리학회 식물병연구 2021, 27권 3호 2 99-106 (8 pages)
The fungal isolate Isaria javanica pf185 has potential as a mycopesticide because it demonstrates insecticidal activity against the green peach aphid and antifungal activity against Colletotrichum gloeosporioides. For com- mercialization of this isolate, determination of the optimal and least expensive culture conditions is required; however, these data are not currently available. This study describes the conditions for optimal development of conidia and production of metabolites for the... -
고추 역병 방제시기 결정을 위한 PBcast 예측모델 타당성 포장 평가

고추 역병의 감염위험도 예측모델인 PBcast 포장검증 연구를2012-2013년 동안 수행하였다. 그리고 2014-2017년 동안 우리나라 26개 지점에서 PBcast 모델을 이용하여 발병환경을 평가하였다. PBcast 모델은 기상과 토성자료를 이용하여 Phytophthora capsici의 일일 감염위험도를 추정한다. 시험포장에서 7일 간격으로 살균제를 살포하는 정기방제(RTN7) 처리, 예측된 감염위험도가 200 이상(IR200), 224 이상(IR224)일 때 살포하는 예찰방제 처리, 무방제(CTRL) 처리를 발병주율과 살균제 살포횟수로 비교하였다. 2012년에 감염위험도가... -
The First Case of Successful Bark Implantation of a 250-year-old Zelkova Tree Heavily Damaged by Artificial Girdling

A circular bark with a 30 cm width was artificially removed from the trunk of a 250-year-old zelkova tree (Zelkova serrata) heavily damaged by artificial girdling in Sunchang, Jeonbuk Province in March of 2005. The debarked area was cleaned approximately 10 days after artificial girdling and bark margins with 2 cm width above and below the girdled portion were cut off to promote wound callus formation. Nine pieces of fresh bark (width 8 cm, length 35 cm, thickness 0.5 cm) were then prepared from...
