Heritability 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 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 کاملProduction of Fumonisin B(inf1) and Moniliformin by Gibberella fujikuroi from Rice from Various Geographic Areas.
Gibberella fujikuroi strains isolated from rice in the United States, Asia, and other geographic areas were tested for sexual fertility with members of mating population D and for production of fumonisin B(inf1) and moniliformin in culture. Of the 59 field strains tested, 32 (54%) were able to cross with tester strains of mating population D, but only a few ascospores were produced in most of t...
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 ...
متن کاملRegulation of Gibberellin Biosynthesis in Gibberella fujikuroi.
Gibberellin production by Gibberella fujikuroi started only after the nitrogen source was depleted and ceased upon its renewal. Nitrogen repression of gibberellin biosynthesis is not an indirect effect of the growth arrest that follows the depletion of an essential nutrient because gibberellins were not produced upon depletion of phosphate. Mycelia produced gibberellins when suspended in a gluc...
