The PHD Transcription Factor Rum1 Regulates Morphogenesis and Aflatoxin Biosynthesis in Aspergillus flavus

Toxins, 2018
Aspergillus flavus produces mycotoxins especially aflatoxin B1 and infects crops worldwide. As a PHD transcription factor, there is no report on the role of Rum1 in the virulence of Aspergillus spp. yet.

PRELIMINARY STRUCTURAL OPTIMIZATION OF SOME FUMONISIN METABOLITES BY DENSITY FUNCTIONAL THEORY CALCULATION [PDF]

Poljoprivreda, 2015
Maize (Zea mays L.) is often contaminated with Fusarium verticillioides. This harmful fungus produces fumonisins as secondary metabolites. These fumonisins can appear both free and hidden form in planta.

Mycotoxin Co-Occurrence in Michigan Harvested Maize Grain

Toxins, 2022
Mycotoxins are secondary metabolites produced by fungi that, depending on the type and exposure levels, can be a threat to human and animal health. When multiple mycotoxins occur together, their risk effects on human and animal health can be additive or ...

The Stress Response Regulator AflSkn7 Influences Morphological Development, Stress Response, and Pathogenicity in the Fungus Aspergillus flavus

Toxins, 2016
This study focused on AflSkn7, which is a stress response regulator in the aflatoxin-producing Aspergillus flavus. The ΔAflSkn7 mutants exhibited partially defective conidial formation and a complete inability to generate sclerotia, indicating AflSkn7 ...

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.
