Grain mold caused by Fusarium verticillioides is one of the most dangerous food and feed safety challenges in sorghum production. The most efficient solution for reducing the hazards of the disease is breeding resistant varieties. In order to find the resistant sorghum varieties, nine sorghum varieties were evaluated for their reaction to F. verticillioides and fumonisin accumulation in their ...

Fusarium proliferatum is a major cause of maize ear rot and fumonisin contamination and also can cause wheat kernel black point disease. The primary objective of this study was to determine whether nine F. proliferatum strains from wheat from Nepal can cause black point and fumonisin contamination in wheat kernels. For comparison, the study included three Fusarium strains from US maize. In test...

Fumonisins are mycotoxins produced by Fusarium moniliforme, a common fungal contaminant of corn worldwide, 10 and F. proliferatum, a closely related species.l.Io.'9 The true incidence of F. moniliforme is difficult to determine because F. proliferatum has often been misidentified as F. moniliforme. lO,'3 Certain strains of F. proliferatum also produce moniliformin, but isolates of F. moniliform...

Sphingolipids are abundant constituents of neuronal membranes and have been implicated in intracellular signaling. We show that two analogs of glycosphingolipid biosynthetic intermediates, fumonisin B1 (which inhibits dihydroceramide synthesis) and DL-1-phenyl-2-palmitoylamino-3-morpholino-1-propanol (PPMP) (which inhibits glucosylceramide synthesis) decrease glycosphingolipid synthesis in rat ...

fumonisin b1 (fb1) is the most abundant of the fumonisin mycotoxins, mainly produced in corn by fungi of the genus fusarium. fb1 has been shown to be hepatocarcinogenic and nephrocarcinogenic in animals. contamination of corn with fb1 was assayed in samples collected from mazandaran province, situated on the caspian littoral of iran, in september 2000. in this survey, 38 corn samples were analy...

The effects of cotton-corn rotation and glyphosate use on levels of soil-borne Aspergillus flavus, aflatoxin and fumonisin contamination in corn and cotton seed were determined during 2002-2005 in Stoneville, Mississippi (USA). There were four rotation systems (continuous cotton, continuous corn, cotton-corn and corn-cotton) for both glyphosate-resistant (GR) and non-GR cultivars-herbicide syst...

Fusarium verticillioides is one of the most important fungal pathogens to cause destructive diseases of maize worldwide. Fumonisins produced by the fungus are harmful to human and animal health. To date, our understanding of the molecular mechanisms associated with pathogenicity and fumonisin biosynthesis in F. verticillioides is limited. Because MAP kinase pathways have been implicated in regu...

The sphingolipid signaling pathway appears to play an important role in regulating vascular tone. We examined the effect of fumonisin B(1), a fungal toxin in corn that blocks ceramide synthase in the sphingolipid signaling pathway, on the ascending aortic impedance spectrum of pigs. Sixteen pigs were fed culture material containing fumonisin B(1) (20 mg/kg body wt) (n = 7) or a control diet (n ...

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...

The two important Fusarium ear rots of corn, Gibberella ear rot (Fusarium graminearum, formally F. moniliforme and allied species) and Fusarium ear rot (F. verticillioides and allied species) grow under different environmental conditions. F. graminearum grows well only between 26 and 28 degrees C and requires rain both at silking and during disease progression. F. verticillioides grows well at ...
