Fusarium graminearum Z-3639 and F. sporotrichioides NRRL3299 produce the trichothecene mycotoxins 15-acetyldeoxynivalenol and T-2 toxin, respectively. These toxins differ in oxygenation at C-4, C-7, and C-8. In F. sporotrichioides, Tri1 (FsTri1) controls C-8 hydroxylation. To determine the function of an apparent F. graminearum Tri1 (FgTri1) homolog, both FsTri1 and FgTri1 genes were heterologo...

Fusarium proliferatum and F. verticillioides are considered as minor pathogens of pea (Pisum sativum L.). Both species can survive in seed material without visible disease symptoms, but still contaminating it with fumonisins. Two populations of pea-derived F. proliferatum and F. verticillioides strains were subjected to FUM1 sequence divergence analysis, forming a distinct group when compared t...

fumonisins (a family of foodborne carcinogenic mycotoxins) cause health hazards to humans and animals in developing countries, and has also economic implications. therefore, the efficacy of a novel environmental friendly nixtamalization procedure to make tortillas (the main staple food for the mexican population) was investigated.maize contaminated with 2136.67 ng/g total fumonisins was process...

Levels of mycotoxins produced by Fusarium species in genetically modified (GM) and near-isogenic maize, were determined using multi-analyte, microbead-based flow immunocytometry with fluorescence detection, for the parallel quantitative determination of fumonisin B1, deoxynivalenol, zearalenone, T-2, ochratoxin A, and aflatoxin B1. Maize varieties included the genetic events MON 810 and DAS-591...

Eighty maize grain samples collected in Nigeria were investigated for fumonisin B1 (FB1) content and Fusarium verticillioides colonization. F. verticillioides DNA was quantified by species-specific real-time PCR and living propagules of the fungus were counted by agar-plating method. FB1 was detected in 55 (68.7%) of the total samples (mean: 98.5 μg/kg, range: 10 to 714 μg/kg) at 10 μg/kg detec...

Fusarium verticillioides is the primary causal agent of Fusarium ear and kernel rot in maize, producing fumonisin mycotoxins that are toxic to humans and domestic animals. Rapid detection and monitoring of fumonisin-producing fungi are pivotally important for the prevention of mycotoxins from entering into food/feed products. Chicken-derived single-chain variable fragments (scFvs) against cell ...

In this study a total of 16 Fusarium verticillioides strains isolated from corn feed samples were characterized by fumonisin (FB) production and random amplified polymorphic DNA (RAPD). All the strains produced FB1 and FB2 with levels ranging from 2.41 to 3996.36 μg/g, and from 1.18 to 1209.91 μg/g, respectively. From the 16 F. verticillioides strains, four were identified as low (3.59 to 1289....

fusarium head blight (fhb) or wheat scab is one of the destructive diseases that cause considerable loss in grain quality in cereal cultivated around the worldwide due to the production of trichotecen mycotoxin in the panicle. type b trichothecenes including nivalenol (niv), deoxynivalenol (don), 3-acetyl deoxynivalenol (3-acdon) and 15-deoxynivalenol (15-acdon) are considered to be major toxin...
