Genetic Characterization by RAPD Analysis of Isolates of Fusarium oxysporum f. sp. erythroxyli Associated with an Emerging Epidemic in Peru.
ABSTRACT An epidemic of vascular wilt caused by Fusarium oxysporum f. sp. erythroxyli is currently occurring on Erythroxylum coca var. coca in the coca-growing regions of the Huallaga Valley in Peru. Random amplified polymorphic DNA (RAPD) analysis of isolates of the pathogen was undertaken to elucidate its genetic complexity, as well as to identify a specific DNA fingerprint for the pathogen. ...

پژمردگی فوزاریومی خربزه و طالبی با عامل fusarium oxysporum f. sp. melonis از بیماری های مهم قارچی در مناطق رشد این گیاهان می باشد. جدایه های f. oxysporum از گیاهان و خاک ریزوسفر متعلق به پنج استان مهم تولیدکننده ی خربزه و طالبی جداسازی شد و بر پایه ی بیماری زایی در ارقام افتراقی، گروه های سازگاری رویشی (vegetative compatibility groups)، توالی سنجی ناحیه ی جداکننده ی بین ژنی دی اِن اِی ریبوزومی (n...
15 صفحه اولAntagonistic Effect of Nonpathogenic Fusarium oxysporum Fo47 and Pseudobactin 358 upon Pathogenic Fusarium oxysporum f. sp. dianthi.
Pseudobactin production by Pseudomonas putida WCS358 significantly improves biological control of fusarium wilt caused by nonpathogenic Fusarium oxysporum Fo47b10 (P. Lemanceau, P. A. H. M. Bakker, W. J. de Kogel, C. Alabouvette, and B. Schippers, Appl. Environ. Microbiol. 58:2978-2982, 1992). The antagonistic effect of Fo47b10 and purified pseudobactin 358 was studied by using an in vitro bioa...
متن کاملBiochemical characterization of Fusarium oxysporum f. sp. cubense isolates from India
The Fusarium wilt caused by Fusarium oxyspoum f. sp. cubense (Foc) is a major biotic constraint for banana production. The characteristics of F. oxyspoum f. sp. cubense isolates were investigated using electrophoretic studies of isozyme and whole-cell protein. The morphological characteristics of the isolates were very similar to each other. All the Foc isolates were pathogenic to banana cultiv...
متن کاملIdentification of Fusarium oxysporum f. sp. basilici Isolated from Soil, Basil Seed, and Plants by RAPD Analysis
Wilt and crown rot of sweet basil (Ocimum basilicum), caused by Fusarium oxysporum f. sp. basilici, represents a major problem on this crop, which is grown in Italy over a large area (approximately 80 ha) under glasshouse, mainly in the Riviera Ligure (5). First reported in Russia (12), F. oxysporum f. sp. basilici has been observed in Italy (6,22), France (15), the United States (1,2,7,24), an...
