The objective of this work was to study the effect of ecophysiological factors on fumonisin gene expression and growth in Fusarium verticillioides. The effects of ionic and nonionic solute water potentials, matric potential, and temperature on in vitro mycelial growth rates and on expression of the FUM1 gene, involved in fumonisin biosynthesis, were examined. FUM1 transcript levels were quantif...

Aim: The present study was designed to evaluate the toxic interaction of fumonisin B and ochratoxin A, alone and in 1 combination for pathology of the kidneys in day old Japanese quail. Materials and Methods: Day old Japanese quail chicks were divided into 4 groups and fed with basal quail chick mash containing fumonisin B @ 200 ppm (Group FX), Ochratoxin A @ 2 ppm (Group OX), and fumonisin B @...

Programmed cell death is essential for plant development and stress adaptation. A detailed understanding of the signal transduction pathways that regulate plant programmed cell death requires identification of the underpinning protein networks. Here, we have used a protagonist and antagonist of programmed cell death triggered by fumonisin B1 as probes to identify key cell death regulatory prote...

Mycotoxin is toxic secondary metabolite synthesized by filamentous fungi during their stationary phase of growth in agricultural crops, food and feed products. Niger State experienced high temperature humidity for about three-quarters the year, these are some conditions that encourage to produce mycotoxin Enzyme Linked Immunosorbent Assay (ELISA) was used dectect mycotoxins. Mycological profile...

The absolute stereochemical description of fumonisin B1 (FB1) and presumably of its congeners is now secure. In this article I summarize studies leading to this conclusion and outline the biosynthetic and synthetic studies of FB1.

This volume of the IARC Monographs considers some traditional herbal medicines, including extracts from certain plants of the genera Aristolochia, Rubia, Morinda and Senecio; some mycotoxins, specifically aflatoxins and fumonisin B1; and two industrial chemicals, naphthalene and styrene. Of these, the Monographs have previously evaluated several of the pyrrolizidine alkaloids that occur in cert...

objectives: the purpose of this study was to evaluate the effect of cuminum cyminum (c. cyminum) essential oil on the growth and fum1 gene expression of fumonisin-producing fusarium verticillioides (f. verticillioides) strains isolated from maize. materials and methods: all fungal strains were cultured on potato dextrose agar (pda) slopes at 30°c for 7 days. the antifungal activity was evaluate...

background : numerous epidemiologic studies have shown that esophagus cancer is more common in areas with grains containing mycotoxin such as fumonisin b1 (fb1). the aim of this research is to study the effect of long- and short-term of esophagus tissue to fb1 orally administered in animal model. materials and methods : forty-four female mice have been divided in two short- and long-term groups...

BACKGROUND Fumonisin B1 (FB1), fumonisin B2 (FB2), and overall mycotoxins feed contamination may cause several effects on crops production and animal health. The contamination occurred predominantly in corn and corn-based foods and feeds. AIMS This survey intends to provide the occurrence of fumonisins in swine and equine mixed feeds in Portugal, making an overview from 2007 to 2010. METHOD...

Fusarium moniliforme (F. moniliforme) is one of the most frequent fungal pathogens found in rice. Samples of rice grown in three different zones of Mazandaran Province, Iran were collected and analyzed for the presence of fumonisin B (FB ). Mycological analysis revealed the presence of F. moniliforme-type isolates 1 1 in 65.1% of the rice samples. Average levels of FB per zones 1, 2 and 3 were ...
