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 ...

Crosstalk between Mycotoxins and Intestinal Microbiota and the Alleviation Approach via Microorganisms

Toxins, 2022
Mycotoxins are secondary metabolites produced by fungus. Due to their widespread distribution, difficulty in removal, and complicated subsequent harmful by-products, mycotoxins pose a threat to the health of humans and animals worldwide.

The Fungi-specific histone Acetyltransferase Rtt109 mediates morphogenesis, Aflatoxin synthesis and pathogenicity in Aspergillus flavus by acetylating H3K9

IMA Fungus, 2021
Aspergillus flavus is a common saprophytic filamentous fungus that produces the highly toxic natural compound aflatoxin during its growth process. Synthesis of the aflatoxins, which can contaminate food crops causing huge losses to the agricultural ...

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 ...

Historical data on fungal contamination of maize (Zea mays L.) from different agroecological zones in Nigeria: a review

Italian Journal of Mycology
Fungi attack maize in the field, and if warm and humid conditions that are suitable for fungal growth and mycotoxin production prevail, they can grow rapidly during storage, causing loss of quantity and quality, a reduction in nutrient content, and ...

Role of Glycerol-3-Phosphate Dehydrogenase in the Development, Pathogenicity, and Glycerol Biosynthesis of Aspergillus flavus

Journal of Fungi
Aspergillus flavus, a ubiquitous phytopathogen, produces mycotoxins, especially aflatoxin B1 (AFB1), and infects crops worldwide. Glycerol-3-phosphate dehydrogenase (G3PDH) is a key enzyme in the glycerol synthesis and metabolic pathway catalyzing the ...
