Fus3, as a Critical Kinase in MAPK Cascade, Regulates Aflatoxin Biosynthesis by Controlling the Substrate Supply in Aspergillus flavus, Rather than the Cluster Genes Modulation

Aspergillus flavus is an important saprophytic fungus that produces aflatoxins (AF), which threaten food and feed safety. MAPK signaling pathways are essential for fungal adaptation to diverse environments.
