Fusarium mycotoxin content of UK organic and conventional wheat.
Each year (2001-2005), 300 samples of wheat from fields of known agronomy were analysed for ten trichothecenes by gas chromatography-mass spectrometry (GC/MS) including deoxynivalenol (DON), nivalenol, 3-acetyl-DON, 15-acetyl-DON, fusarenone X, T2 toxin, HT2 toxin, diacetoxyscirpenol, neosolaniol and T-2 triol and zearalenone by high-performance liquid chromatography (HPLC). Of the eleven mycot...
متن کاملThe content of Fusarium mycotoxins, grain yield and quality of winter wheat cultivars under organic and conventional cropping systems
Nine cultivars of winter wheat were compared in organic and conventional crop rotation systems. Bread-making quality was evaluated using three parameters [thousand-kernel weight (TKW) in g, volume weight in g/l, protein content in %]. Grain yield, TKW and protein content of winter wheat in organic cropping system were significantly lower as compared to any intensity in conventional cropping sys...
متن کاملIsolation and Structure Elucidation of Pentahydroxyscirpene, a Trichothecene Fusarium Mycotoxin
Pentahydroxyscirpene, a novel trichothecene-type compound, was isolated from Fusarium-inoculated rice. The structure of pentahydroxyscirpene was elucidated by 1D and 2D NMR spectroscopy and X-ray single-crystal diffraction. The conformation in solution was determined by NOESY experiments supported by quantum chemical calculations. In vitro toxicity tests showed that pentahydroxyscirpene inhibit...
متن کاملRNA silencing of mycotoxin production in Aspergillus and Fusarium species.
Mycotoxins are natural fungal products that are defined by their harmful effects on humans and animals. Aflatoxin contamination of maize by Aspergillus species and trichothecene contamination of small grains by Fusarium species are two of the most severe mycotoxin problems in the United States. We are investigating RNA silencing in an effort to identify novel ways to control mycotoxin contamina...
متن کاملQuantification of Fusarium species in Swedish Spring wheat by real-time PCR and their correlation with mycotoxin content and region
Fusarium is a type of mould capable of producing several diseases in cereals. Infection is a worldwide problem associated with yield losses and the accumulation of toxic secondary metabolites, mycotoxins, which are harmful to both humans and animals. F. graminearum, F. culmorum, F. avenaceum, F. poae, and F. tricinctum, including corresponding mycotoxins were quantified in wheat samples from 6 ...
