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 ...

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.

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.

Mycotoxins and Mycotoxin Producing Fungi in Pollen: Review [PDF]

Toxins, 2019
Due to its divergent chemical composition and good nutritional properties, pollen is not only important as a potential food supplement but also as a good substrate for the development of different microorganisms. Among such microorganisms, toxigenic fungi are extremely dangerous as they can synthesize mycotoxins as a part of their metabolic pathways ...

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 ...

Intermolecular Carbon–Carbon Naphthalene Coupling Involves a Radical Mechanism Driven by Cytochrome P450 in Alternaria alternata

Angewandte Chemie, EarlyView.
1,8‐DHN is an important intermediate to form complex aromatic ring systems. Phenol‐coupling reactions are important for the dimerization of two molecules. Here, we show that a fungal cytochrome P450 enzyme catalyzes specific C─C bonds. ABSTRACT Dihydroxynaphthalene (DHN) derivatives are precursors of biologically important molecules, including melanin ...

Characterization of a Fungal Modular Polyketide Synthase System Reveals an Unusual Strategy for Polyketide Chain Initiation

Angewandte Chemie, EarlyView.
Fungal modular polyketide synthases (PKSs) remain largely unexplored. Functional characterization of the LasC/LasD assembly line established its role in strasseriolide C biosynthesis and suggested an unexpected strategy for chain initiation, in which a malonyl unit is transferred from the module 2 acyl carrier protein (ACP) domains to the loading ACP ...

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.
