Susceptibility of Douglas fir ( Pseudotsuga menziesii ) to pitch canker , caused by Gibberella circinata ( anamorph = Fusarium circinatum )
For better characterization of the risk of pitch canker (caused by Gibberella circinata , anamorph = Fusarium circinatum ) to Douglas fir ( Pseudotsuga menziesii ), Californian isolates, selected exotic isolates, and ascospore progeny of a cross between wild-type Californian isolates were tested for aggressiveness to this host species. In addition, seedlings from representative provenances of P...
متن کاملRegulation of Trichodiene Synthase in Fusarium sporotrichioides and Gibberella pulicaris (Fusarium sambucinum).
The regulation of trichodiene synthase (TS) and its relationship to trichothecene biosynthesis was investigated in Fusarium sporotrichioides NRRL 3299 and Gibberella pulicaris R-6380. Cultures were analyzed for the presence of TS activity, trichothecenes, and immunodetectable TS polypeptide over a time period of 144 h. Enzyme activity increased from barely detectable to maximum levels over a pe...
متن کاملVariation in susceptibility to pitch canker disease, caused by Fusarium circinatum , in native stands of Pinus muricata
Two hundred Pinus muricata trees, located within a native forest near Monterey, California, were inoculated with the pitch canker pathogen. Treated branches were removed 10–13 weeks following the initial inoculation, and the lengths of the lesions that developed at each of the inoculation sites were measured. Results indicated that bishop pine exhibits a wide range of variation in susceptibilit...
متن کاملTolerance and Metabolism of Furanocoumarins by the Phytopathogenic Fungus Gibberella Pulicaris (fusarium Sambucinum)
Sixty-two strains of Gibberella pulicaris (anamorph: Fusarium sambucinum) from diseased plants and from soil were tested for tolerance of the furanocoumarin xanthotoxin in vitro. Twenty-one (88%) of the plant-derived strains and two (5%) of the soil-derived strains were highly tolerant ofxanthotoxin. Sixteen selected strains were tested further against 16 furanocoumarins or furanocoumarin precu...
متن کاملProduction of volatile sesquiterpenes by Fusarium sambucinum strains with different abilities to synthesize trichothecenes.
Twenty-five strains of Fusarium sambucinum grown on wheat kernels were examined for trichothecene production and the synthesis of volatile sesquiterpenes. The volatiles were purged with air and collected on Tenax traps. Adsorbed compounds were eluted from the traps and injected into a gas chromatograph coupled with a mass spectrometer. Ten strains isolated from potato tubers produced high amoun...
