Biocontrol of Potato White Mold Using Coniothyrium minitans and Resistance of Potato Cultivars to Sclerotinia sclerotiorum
한국식물병리학회 The Plant Pathology Journal 7 Pages
한국식물병리학회 The Plant Pathology Journal 2010, 26권 4호 7 346-352 (7 pages)
This study was conducted in Bahar and Lalehjin, Hamadan, Iran to assess the biocontrol efficacy of Coniothyrium minitans Campbell against potato white mold caused by Sclerotinia sclerotiorum (Lib.) de Bary under field and greenhouse conditions. In addition, the resistance of common potato cultivars against S. sclerotiorum was determined in a greenhouse experiment. After straw inoculation of six potato cultivars (Pashandi, Istambouli, Agria, Marfauna, Alpha and Spartaan) with S. sclerotiorum, the... -
Comparison of Microbial Fungicides in Antagonistic Activities Related to the Biological Control of Phytophthora Blight in Chili Pepper Caused by Phytophthora capsici
한국식물병리학회 The Plant Pathology Journal 6 Pages
한국식물병리학회 The Plant Pathology Journal 2010, 26권 4호 6 340-345 (6 pages)
Two similar microbial fungicides (termed as MA and MB) developed in a Korean biopesticide company were analyzed and compared each other in their biocontrol activities against the phytophthora blight of chili pepper caused by Phytophthora capsici. MA and MB contained the microbe Paenibacillus polymyxa and Bacillus subtilis, respectively, with concentrations over those posted on the microbial products. In comparison of the isolated microbes (termed as MAP from MA and MBB from MB) in the... -
Genetic Stability of Magnaporthe oryzae during Successive Passages through Rice Plants and on Artificial Medium
한국식물병리학회 The Plant Pathology Journal 8 Pages
한국식물병리학회 The Plant Pathology Journal 2010, 26권 4호 3 313-320 (8 pages)
a major factor underlying the rapid breakdown of host resistance in the field. However, little information is available on the mechanism of genetic instability. In this study, we assessed the stability of repetitive DNA elements and several key phenotypic traits important for pathogenesis after serially transferring two isolates though rice plants and an artificial medium. Using isolate 70-15, we obtained a total of 176 single-spore isolates from 10 successive rounds of culturing on artificial... -
Evaluation on Red Pepper Germplasm lines (Capsicum spp.) for Resistance to Anthracnose Caused by Colletotrichum acutaum
한국식물병리학회 The Plant Pathology Journal 7 Pages
한국식물병리학회 The Plant Pathology Journal 2010, 26권 3호 12 273-279 (7 pages)
We evaluated 209 Capsicum accessions from the National Agrobiodiversity of RDA, for their reaction against of anthracnose disease caused by Colletotrichum acutatum. Two hundred nine accessions of Capsicum were almost composed with Capsicum annuum var. annuum originated from 37 countries. The percentage of infection due to C. acutatum ranged from 11.1% to 100% on immature and matured pepper fruits at 21 days after inoculation. On immature fruits of pepper, one hundred seventy three accessions of... -
Oomycetes RXLR Effectors Function as Both Activator and Suppressor of Plant Immunity

the host plant. Apoplastic effectors are secreted into the plant extracellular space, and cytoplasmic effectors are translocated inside the plant cell, through the haustoria that enter inside living host cell. Recent characterization of some oomycete Avr genes showed that they encode effector protein with general modular structure including N-terminal conserved RXLR-DEER motif. More detailed evidences suggest that these AVR effectors are secreted by the pathogenic oomycetes and then translocated... -
Effect of Acibenzolar-S-methyl and Rahnella aquatilis (Ra39) on Chitinase and β-1, 3-glucanase Activities and Disease Resistance of Apple Plants
한국식물병리학회 The Plant Pathology Journal 7 Pages

the pathogen within host plants up to 64% and 49.5% respectively. Further studies in the field under artificial infection condition during full bloom revealed that application of ASM and R. aquatilis Ra39 with Gala variety resulted in a control effect up to 21 and 29% respectively. In physiological studies, enhanced activities of PR-proteins (chitinase and β-1, 3-glucanase) were detected, which are well known as biochemical markers for systemic acquired resistance. Application of ASM to apple... -
Survey of Egg- and Cyst-parasitic Fungi of Potato Cyst Nematode in Indonesia
한국식물병리학회 The Plant Pathology Journal 5 Pages
한국식물병리학회 The Plant Pathology Journal 2010, 26권 1호 5 32-36 (5 pages)
Twelve fungal isolates out of 123 isolates obtained from cysts and soils of potato cyst nematode (PCN)-infested fields in Central Java, Indonesia had parasitic abilities of over 50% on PCN eggs or females (cysts) in vitro pathogenicity tests. Cultural and morphological characters and DNA sequences of ribosomal genes in ITS region revealed that they were four isolates of Gliocladium (Trichoderma) virens, three isolates of Fusarium oxysporum, one of F. lateritium, one of Penicillium tritinum and... -
A Short-chain Dehydrogenase/reductase Gene is Required for Infection-related Development and Pathogenicity in Magnaporthe oryzae
한국식물병리학회 The Plant Pathology Journal 9 Pages
한국식물병리학회 The Plant Pathology Journal 2010, 26권 1호 2 8-16 (9 pages)
basis of M. oryzae pathogenic development, we previously analyzed a library of T-DNA insertional mutants of M. oryzae, and identified ATMT0879A1 as one of the pathogenicity-defective mutants. Molecular analyses and database searches revealed that a single TDNA insertion in ATMT0879A1 resulted in functional interference with an annotated gene, MGG00056, which encodes a short-chain dehydrogenase/reductase (SDR). The mutant and annotated gene were designated as MoSDR1T-DNA and MoSDR1, respectively.... -
A Bacterial Endophyte, Pseudomonas brassicacearum YC5480 Isolated from the Root of Artemisia sp. Producing Antifungal and Phytotoxic Compounds
한국식물병리학회 The Plant Pathology Journal 8 Pages
한국식물병리학회 The Plant Pathology Journal 2008, 24권 4호 13 461-468 (8 pages)
An endophytic bacterial strain YC5480 producing antifungal and phytotoxic compounds simultaneously was isolated from the surface sterilized root of Artemisia sp. collected at Jinju area, Korea. The bacterial strain was identified as a species of Pseudomonas brassicacearum based on its 16S rRNA gene sequence analysis and physiological and biochemical characteristics. The seed germination and growth of monocot and dicot plants were inhibited by culture filtrate (1/10-strength Tryptic Soy Broth) of...
