DON mycotoxin biosynthesis

Gibberella zeae (Fusarium graminearum) is a fungal pathogen of major staple food crops including wheat, maize and rice. The fungus produces a range of mycotoxins including the dexoynivalenol (DON) trichothecene mycotoxin. DON contamination of food crops is a major thread to human and animal health. In wheat, but not in maize, DON was proven to be a virulence factor.
