Reduced virulence of Gibberella zeae caused by disruption of a trichothecene toxin biosynthetic gene.
The production of trichothecene mycotoxins by some plant pathogenic species of Fusarium is thought to contribute to their virulence. Gibberella zeae (F. graminearum) is an important cereal pathogen that produces the trichothecene deoxynivalenol. To determine if trichothecene production contributes to the virulence of G. zeae, we generated trichothecene-deficient mutants of the fungus by gene di...
متن کاملGibberella zeae ascospore production and collection for microarray experiments.
Fusarium graminearum Schwabe (teleomorph Gibberella zeae) is a plant pathogen causing scab disease on wheat and barley that reduces crop yield and grain quality. F. graminearum also causes stalk and ear rots of maize and is a producer of mycotoxins such as the trichothecenes that contaminate grain and are harmful to humans and livestock (Goswami and Kistler, 2004). The fungus produces two types...
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 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 کاملAlignment of genetic and physical maps of Gibberella zeae.
We previously published a genetic map of Gibberella zeae (Fusarium graminearum sensu lato) based on a cross between Kansas strain Z-3639 (lineage 7) and Japanese strain R-5470 (lineage 6). In this study, that genetic map was aligned with the third assembly of the genomic sequence of G. zeae strain PH-1 (lineage 7) using seven structural genes and 108 sequenced amplified fragment length polymorp...
