Head Blight Gradients Caused by Gibberella zeae from Area Sources of Inoculum in Wheat Field Plots.
ABSTRACT The spread of Fusarium head blight of wheat from a small area inoculum source was examined in wheat plots (100, 625, or 2,500 m(2)) inoculated in the center with Gibberella zeae-colonized corn kernels or macro-conidia sprayed on heads at anthesis. With the first inoculation method, disease foci were produced from ascospores released from perithecia formed on inoculated kernels. With th...
متن کاملSome Genetic Techniques for Gibberella zeae
Leslie, J. F. 1983. Some genetic techniques for Gibberella zeae. Phytopathology 73:1005-1008. Gibberella zeae, an important plant pathogen, is exploited commercially dependent, glutamate dehydrogenase-deficient mutant. Protoplasts were in the production of zearalenone, a fungal sex hormone. Genetically, G. liberated by hyphal digestion with commercially available f-glucuronidase zeae is relativ...
متن کاملGenetic Mapping of Pathogenicity and Aggressiveness of Gibberella zeae (Fusarium graminearum) Toward Wheat.
ABSTRACT Gibberella zeae is the major fungal pathogen of Fusarium head blight of wheat and produces several mycotoxins that are harmful to humans and domesticated animals. We identified loci associated with pathogenicity and aggressiveness on an amplified fragment length polymorphism based genetic map of G. zeae in a cross between a lineage 6 nivalenol producer from Japan and a lineage 7 deoxyn...
متن کاملPopulation differentiation and recombination in wheat scab populations of Gibberella zeae from the United States.
In limited previous studies of the Ascomycete fungus Gibberella zeae in North America, the populations examined were genetically and phenotypically diverse and could be viewed as subsamples of a larger population. Our objective in this study was to test the hypothesis that a homogeneous, randomly mating population of G. zeae is contiguous throughout the central and eastern United States across ...
متن کاملComparative mycotoxin profiles of Gibberella zeae populations from barley, wheat, potatoes, and sugar beets.
Gibberella zeae is one of the most devastating pathogens of barley and wheat in the United States. The fungus also infects noncereal crops, such as potatoes and sugar beets, and the genetic relationships among barley, wheat, potato, and sugar beet isolates indicate high levels of similarity. However, little is known about the toxigenic potential of G. zeae isolates from potatoes and sugar beets...
