Nitrate reduction mutants of fusarium moniliforme (gibberella fujikuroi).
Twelve strains of Fusarium moniliforme were examined for their ability to sector spontaneously on toxic chlorate medium. All strains sectored frequently; 91% of over 1200 colonies examined formed chlorate-resistant, mutant sectors. Most of these mutants had lesions in the nitrate reduction pathway and were unable to utilize nitrate (nit mutants). nit mutations occurred in seven loci: a structur...
متن کاملGenetic Analysis of Fumonisin Production and Virulence of Gibberella fujikuroi Mating Population A (Fusarium n10nilifolme) on Maize
The phytopathogenic fungus Gibberella jujikuroi mating population A (anamorph, Fusarium mOlliliforme) produces fumonisins, which are toxic to a wide range of plant and animal species. Previous studies of field strains have identified a genetic locus, designatedjiulll, that can determine whether fumonisins are produced. To test the relationship between fumonisin production and virulence on maize...
متن کاملHeritability of fumonisin B1 production in Gibberella fujikuroi mating population A.
Fumonisins are mycotoxins produced by strains belonging to several different mating populations of Gibberella fujikuroi (anamorphs, Fusarium section Liseola), a major pathogen of maize and sorghum worldwide. We studied the heritability of fumonisin production in mating population A by crossing fumonisin-producing strains collected from maize and sorghum in the United States with fumonisin-nonpr...
متن کاملMating populations of fusarium section liseola from rice, sugarcane and maize.
Mating studies were conducted on 78 isolates of Fusarium species section Liseola from rice, sugarcane and maize. From the crosses with tester strains of Gibberella fujikuroi species complex, 64.1% (50 out of 78 isolates) were cross-fertile with tester strains of mating populations A to E. The results of the mating studies showed that of the 50 isolates, 19 belonged to mating population A (Gibbe...
متن کاملIncidence of Fusarium spp. and levels of fumonisin B1 in maize in western Kenya.
Maize kernel samples were collected in 1996 from smallholder farm storages in the districts of Bomet, Bungoma, Kakamega, Kericho, Kisii, Nandi, Siaya, Trans Nzoia, and Vihiga in the tropical highlands of western Kenya. Two-thirds of the samples were good-quality maize, and one-third were poor-quality maize with a high incidence of visibly diseased kernels. One hundred fifty-three maize samples ...
