Mycotoxins [PDF]

Clinical Microbiology Reviews, 2003
SUMMARYMycotoxins are secondary metabolites produced by microfungi that are capable of causing disease and death in humans and other animals. Because of their pharmacological activity, some mycotoxins or mycotoxin derivatives have found use as antibiotics, growth promotants, and other kinds of drugs; still others have been implicated as chemical ...

NX Trichothecenes Are Required for Fusarium graminearum Infection of Wheat

Molecular Plant-Microbe Interactions, 2023
Fusarium graminearum causes Fusarium head blight (FHB) on wheat and barley and contaminates grains with various mycotoxins that are toxic to humans and animals.

Chitin and laminarin additively trigger wheat reactive oxygen species but not resistance to Fusarium head blight

Plant Direct, 2023
Plants respond to fungal infections by activating defense genes including producing reactive oxygen species (ROS). The fungus Fusarium graminearum causes Fusarium head blight (FHB), a serious disease of wheat and barley.

Isolation and identification of Serratia marcescens Ha1 and herbicidal activity of Ha1 ‘pesta’ granular formulation

Journal of Integrative Agriculture, 2015
A total of 479 bacterial strains were isolated from brine (Bohai, Qinhuangdao City, Hebei Province, China). Bioassay results indicated that 4 strains named Ha1, Ha17, Ha38, and Ha384 had herbicidal activity.

Stk2, a Mitogen-Activated Protein Kinase from Setosphaeria turcica, Specifically Complements the Functions of the Fus3 and Kss1 of Saccharomyces cerevisiae in Filamentation, Invasive Growth, and Mating Behavior

Journal of Integrative Agriculture, 2013
Setosphaeria turcica, an essential phytopathogenic fungus, is the primary cause of serious yield losses in corn; however, its pathogenic mechanism is poorly understood.

MAP kinase gene STK1 is required for hyphal, conidial, and appressorial development, toxin biosynthesis, pathogenicity, and hypertonic stress response in the plant pathogenic fungus Setosphaeria turcica

Journal of Integrative Agriculture, 2016
The mitogen-activated protein kinase (MAPK), a key signal transduction component in the MAPK cascade pathway, regulates a variety of physiological activities in eukaryotes. However, little is known of the role MAPK plays in phytopathogenic fungi. In this

Bis-naphthopyrone pigments protect filamentous ascomycetes from a wide range of predators

Nature Communications, 2019
It is thought that fungi protect themselves from predators by the production of toxic compounds. Here, Xu et al. show that a wide range of animal predators avoid feeding on Fusarium fungi, and this depends on fungal production of a bis-naphthopyrone ...

Opinion: Multi-Mycotoxin Reference Materials

Foods, 2022
The analysis of mycotoxins in food and feed using liquid chromatography coupled with mass spectrometry is considered advantageous because the hyphenated technology enables simultaneous determination of multiple mycotoxins.

Climate Change and Aflatoxin B₁ in Agriculture Products: A Systematic Review. [PDF]

Food Sci Nutr
Climate change mainly involves increasing temperatures and concentrations of the greenhouse gas carbon dioxide. These changes increase the expression of genes for mycotoxin synthesis, including aflatoxin B1, in fungi. These stressors also lead to reduced plant defenses against fungal infections.

Performance of Broilers Fed with Maize Colonized by Either Toxigenic or Atoxigenic Strains of Aspergillus flavus with and without an Aflatoxin-Sequestering Agent

Toxins, 2019
In warm agricultural areas across the globe, maize, groundnut, and other crops become frequently contaminated with aflatoxins produced primarily by the fungus Aspergillus flavus.
