Open Access : Specific and Sensitive Detection of Venturia nashicola, the Scab Fungus of Asian Pears, by Nested PCR
한국식물병리학회 The Plant Pathology Journal 7 Pages
한국식물병리학회 The Plant Pathology Journal 2013, 29권 4호 1 357-363 (7 pages)
The fungus Venturia nashicola is the causal agent of scab on Asian pears. For the rapid and reliable identification as well as sensitive detection of V. nashicola, a PCR-based technique was developed. DNA fingerprints of three closely related species, V. nashicola, V. pirina, and V. inaequalis, were obtained by random amplified polymorphic DNA (RAPD) analysis. Two RAPD markers specific to V. nashicola were identified by PCR, after which two pairs of sequence characterized amplified region (SCAR)... -
Phyllosticta musarum Infection-Induced Defences Suppress Anthracnose Disease Caused by Colletotrichum musae in Banana Fruits cv Embul
한국식물병리학회 The Plant Pathology Journal 10 Pages
한국식물병리학회 The Plant Pathology Journal 2013, 29권 1호 9 77-86 (10 pages)
Anthracnose development by Colletotrichum musae was observed to be significantly less in the fruits of the banana cultivar ``Embul`` (Mysore, AAB) infected with Phyllosticta musarum than in fruits without such infections. Anthracnose disease originates from quiescent C. musae infections in the immature fruit. P. musarum incites minute, scattered spots, referred to as freckles, in the superficial tissues of immature banana peel which do not expand during maturation or ripening. P. musarum does... -
Morphology, Molecular Phylogeny and Pathogenicity of Colletotrichum panacicola Causing Anthracnose of Korean Ginseng
한국식물병리학회 The Plant Pathology Journal 7 Pages
한국식물병리학회 The Plant Pathology Journal 2011, 27권 1호 1 1-7 (7 pages)
Colletotrichum panacicola isolates were obtained from anthracnose lesions of Korean ginseng and compared with four Colletotrichum species in morphology, molecular phylogeny and pathogenicity. Based on morphological characteristics, C. panacicola was easily distinguished from Colletotrichum gloeosporioides but not from Colletotrichum higginsianum, Colletotrichum destructivum and Colletotrichum coccodes. A phylogenetic tree generated from ribosomal DNA-internal transcribed spacer sequences... -
Isolation and Morphological Characterization of Monilinia sp. KV-27 Associated with Apple Anthracnose of Fuji Apples in Korea
한국식물병리학회 The Plant Pathology Journal 4 Pages
한국식물병리학회 The Plant Pathology Journal 2010, 26권 2호 12 185-188 (4 pages)
a fungal pathogen Monilinia sp. KV-27 associated with apple anthracnose. Rotted Fuji apples were used for the isolation of the fungus. The infected tissues were sterilized with 70% ethanol, washed with sterilized distilled water and were transferred to 50 ml containing potato dextrose broth (PDB) flasks. The peripheral hyphae of the fungal colony which developed from the infected tissues were isolated on to potato dextrose agar (PDA). On PDA plates the fungus grew well at 25oC and occupied more... -
Nonlinear Regression Analysis to Determine Infection Models of Colletotrichum acutatum Causing Anthracnose of Chili Pepper Using Logistic Equation
한국식물병리학회 The Plant Pathology Journal 8 Pages
한국식물병리학회 The Plant Pathology Journal 2010, 26권 1호 3 17-24 (8 pages)
A logistic model for describing combined effects of both temperature and wetness period on appressorium formation was developed using laboratory data on percent appressorium formation of Colletotrichum acutatum. In addition, the possible use of the logistic model for forecasting infection risks was also evaluated as compared with a first-order linear model. A simplified equilibrium model for enzymatic reactions was applied to obtain a temperature function for asymptote parameter (A) of logistic... -
ABA Increases Susceptibility of Pepper Fruits to Infection of Anthracnose by Collectotrichum acutatum

of ABA caused the development of pepper anthracnose in fruits of Capsicum baccatum cvs. PBC80 and PBC81, which were previously resistant to the disease. Furthermore, ABA administration rendered increased pathogenicity of other isolates of C. acutatum BAC02063, PECH10, and TCBNU3 obtained from the Chinese matrimony vine, peach, and tea tree, respectively. Our data suggest that exogenous ABA may result in the suppression of defense mechanisms of pepper fruits against anthracnose, which leads to a... -
Effect of Delayed Inoculation After Wounding on the Development of Anthracnose Disease Caused by Colletotrichum acutatum on Chili Pepper Fruit
한국식물병리학회 The Plant Pathology Journal 8 Pages
한국식물병리학회 The Plant Pathology Journal 2008, 24권 4호 4 392-399 (8 pages)
modifications were found with proliferation of fungal hyphae in SI. Sclerenchyma-like cells with thickened cell walls were proliferated around the wounding sites, which were partially dissolved by DWI, probably leading to some disease development. All of these results suggest that the decline of the anthracnose disease in pepper fruit by the delayed inoculations may be derived from the structural modifications related to the healing processes of the previous wound inflicted on the tissues. -
Occurrence of Anthracnose on Peach Tree Caused by Colletotrichum Species
한국식물병리학회 The Plant Pathology Journal 4 Pages
한국식물병리학회 The Plant Pathology Journal 2008, 24권 1호 13 80-83 (4 pages)
C. acutatum caused anthracnose symptoms on the fruits by both wound and unwound inoculation, which were similar to those observed in the orchard. The symptoms appeared more rapidly by the wound inoculation than by the unwound inoculation. There was no difference in pathogenicity between the C. gloeosporioides and C. acutatum isolates tested. In Korea, only C. gloeosporioides has been recorded as the causal fungus of anthracnose of peach tree. This is the first report that C. acutatum also causes... -
First Report of Anthracnose Caused by Colletotrichum acutatum on Begonia(Begonia semperflorens Link.) Nurseries

한국식물병리학회 The Plant Pathology Journal 2006, 22권 1호 2 7-10 (4 pages)
identified as Colletotrichum acutatum on the basis of the mycological characteristics on potato dextrose agar and RAPD analysis. Pathogenicity of the fungus was also confirmed by artificial inoculation on healthy plants. The optimum temperature for mycelial growth of C. acutatum was around 25oC. The fungus was sensitive to azoxystrobin, bitertanol, diethofencarb-carbendazim, difenoconazole and tebuconazole. This is the first report on the anthracnose of begonia caused by C. acutatum in Korea.
