The Fungal Pathogen Fusarium graminearum Can Hydrolyse Tryptamine-Derived Hydroxy-Cinnamic Acid Amide Defence Compounds, and Generates Highly Increased Auxin Levels in Wheat via Copper Amine-Oxidases. [PDF]

Mol Plant Pathol
Fusarium graminearum can cleave tryptamine‐derived hydroxycinnamic acid amides and convert the released tryptamine into auxin, suppressing plant defence responses; aoxΔ7—septuple knockout of copper amine oxidases blocks auxin formation. ABSTRACT The important cereal pathogen Fusarium graminearum is not only able to produce trichothecene toxins, like ...

The Role of Nitrogen Fertilization on the Occurrence of Regulated, Modified and Emerging Mycotoxins and Fungal Metabolites in Maize Kernels

Toxins, 2022
The European Food Safety Authority is currently evaluating the risks related to the presence of emerging mycotoxins in food and feeds. The aim of this study was to investigate the role of soil fertility, resulting from different nitrogen fertilization ...

Mycotoxins-contaminated wheat matrices bioconversion by Tenebrio molitor larvae (Coleoptera: Tenebrionidae). [PDF]

Insect Sci
Larval development time, ADG, survival rate and substrate consumption were not negatively affected by the levels of mycotoxins contamination Larvae excreted most of the ingested DON and its derivatives through exuviae and frass The mycotoxin accumulation rates observed in larvae were always below the current legal limits for livestock feed Abstract ...

Occurrence of Fusarium Mycotoxins and Their Modified Forms in Forage Maize Cultivars

Toxins, 2021
Forage maize is often infected by mycotoxin-producing Fusarium fungi during plant growth, which represent a serious health risk to exposed animals. Deoxynivalenol (DON) and zearalenone (ZEN) are among the most important Fusarium mycotoxins, but little is

In Vitro Wheat Immature Spike Culture Screening Identified Fusarium Head Blight Resistance in Wheat Spike Cultured Derived Variants and in the Progeny of Their Crosses with an Elite Cultivar

The Plant Pathology Journal, 2020
Fusarium head blight (FHB) is a devastating fungal disease of wheat (Triticum aestivum L.). The lack of genetic resources with stable FHB resistance combined with a reliable and rapid screening method to evaluate FHB resistance is a major limitation to ...

Mycotoxins in Maize Silage from China in 2019

Toxins, 2022
Animal feed (including forage and silage) can be contaminated with mycotoxins. Here, 200 maize silage samples from around China were collected in 2019 and analyzed for regulated mycotoxins, masked mycotoxins (deoxynivalenol, 3-acetyldeoxynivalenol, 15 ...

Aberrant Behavior of Deoxynivalenol Production in the Malting of Fusarium Head Blight Infected Barley: Mycotoxin Accumulation and Hyphal Localization in Single Kernels

, 2023
The malting industry faces a dilemma in which barley, initially containing low deoxynivalenol levels, occasionally exhibits an unexpected increase in deoxynivalenol levels during malting.

Effect of Fungicide Treatment on Multi-Mycotoxin Occurrence in French Wheat during a 4-Year Period

Toxins, 2023
Wheat represents one of the most widely consumed cereals worldwide. Cultivated in winter and spring, it is vulnerable to an array of different pathogens, including fungi, which are managed largely through the in-field application of fungicides.

Contamination of Wheat Cultivated in Various Regions of Poland during 2017 and 2018 Agricultural Seasons with Selected Trichothecenes and Their Modified Forms

Toxins, 2019
Cross-interaction of antibodies within the immunoaffinity columns used in this study facilitated the simultaneous determination of nivalenol (NIV), deoxynivalenol (DON), their glucoside derivatives (NIV-3G, DON-3G), and 3-acetyl-deoxynivalenol (3-AcDON ...
