Natural Contamination with Mycotoxins Produced by Fusarium graminearum and Fusarium poae in Malting Barley in Argentina
Two of the most common species of toxin-producing Fusarium contaminating small cereal grains are Fusarium graminearum and F. poae; with both elaborating diverse toxins, especially deoxynivalenol (DON) and nivalenol (NIV), respectively. The objective of our work during the 2012-2014 growing seasons was to screen crops for the most commonly isolated Fusarium species and to quantify DON and NIV to...
متن کاملUse of a Gfp Strain of Fusarium Graminearum for Histological Investigation of Infected Barley
We are investigating development of Fusarium graminearum on and in barley florets and other organs using a transformed strain of the fungus containing a constitutively expressed gene for green fluorescent protein (GFP). The GFP strain fluoresces green when viewed by fluorescence microscopy under blue or blue-violet incident light. The GFP strain is easier to see in inoculated living florets, le...
متن کاملDistribution of Mycelial Colonies and Lesions in Field-Grown Barley Inoculated with Fusarium graminearum.
ABSTRACT External surfaces of barley florets have thick-walled epidermal cells resistant to direct penetration by the head blight pathogen, Fusarium graminearum. Surfaces within the floral cavity have thin-walled, susceptible cells. How the fungus gains access to the floral cavity, causing head blight, has not been determined. To investigate pathways of entry, field-grown plants were sprayed wi...
متن کاملTransgenic wheat expressing a barley class II chitinase gene has enhanced resistance against Fusarium graminearum
Fusarium head blight (FHB; scab), primarily caused by Fusarium graminearum, is a devastating disease of wheat worldwide. FHB causes yield reductions and contamination of grains with trichothecene mycotoxins such as deoxynivalenol (DON). The genetic variation in existing wheat germplasm pools for FHB resistance is low and may not provide sufficient resistance to develop cultivars through traditi...
متن کاملFunctional analysis of the Fusarium graminearum phosphatome.
Phosphatases are known to play important roles in the regulation of various cellular processes in eukaryotes. However, systematic characterization of the phosphatome has not been reported in phytopathogenic fungi. The wheat scab fungus Fusarium graminearum contains 82 putative phosphatases. The biological functions of each phosphatase were investigated in this study. Although 11 phosphatase gen...
