Local origin of two vegetative compatibility groups of Fusarium oxysporum f. sp. vasinfectum in Australia
Pathogenicity and genetic diversity of Fusarium oxysporum from geographically widespread native Gossypium populations, including a cotton growing area believed to be the center of origin of VCG 01111 and VCG 01112 of F. oxysporum f. sp. vasinfectum (Fov) in Australia, was determined using glasshouse bioassays and AFLPs. Five lineages (A-E) were identified among 856 isolates. Of these, 12% were ...
متن کاملgenetic relationship among fusarium oxysporum f. sp. melonis vegetative compatibility groups and their relatedness to other f. oxysporum formae speciales
fusarium wilt of melon is a destructive fungal disease throughout the world. in this study, the evolutionary relationships among isolates of different formae speciales of fusarium oxysporum was examined, with a special emphasis on the forma specialis melonis. bootstrapped maximum likelihood analysis of the elongation factor-1α (ef-1α) sequence was conducted on 16 iranian and 11 foreign isolates...
متن کاملDifferentiation of Fusarium oxysporum f. sp. vasinfectum races on cotton by random amplified polymorphic DNA (RAPD) analysis
Assigbetse, K. B., Fernandez, D., Dubois, M. P., and Geiger, J.-P. 1994. Differentiation of Fusarium oxysporum f. sp. vasinfectum races on cotton by random amplified polymorphic DNA (RAPD) analysis. Phytopathology 84:622-626. We used pathogenicity and random amplified polymorphic DNA (RAPD) markers to assess genetic diversity among 46 isolates of Fusarium ox~~sporum f. sp. vasinfectuni of world...
متن کامل1274 Origin and evolution of Fusarium oxysporum f. sp. vasinfectum: A case study in Australia
In Australia, indigenous Fusarium oxysporum consist of at least five genetically distinct lineages and the two strains (VCG 11&12) of F. oxysporum f. sp. vasinfectum (Fov) are genetically related to lineage A, suggesting that they evolved locally. This is consistent with the observation that virulence of a lineage A isolate increased after 10 successive infections on susceptible cotton in the g...
متن کاملInteraction of Population Levels of Fusarium oxysporum f. sp. vasinfectum and Meloidogyne incognita on Cotton.
In autoclaved greenhouse soil without Fusarium oxysporum f. sp. vasinfectum, Meloidogyne incognita did not cause leaf or vascular discoloration of 59-day-old cotton plants. Plants had root galls with as few as 50 Meloidogyne larvae per plant. Root galling was directly proportional to the initial nematode population level. Fusarium wilt symptoms occurred without nematodes with 77,000 fungus prop...
