Fusaric acid is a picolinic acid - derivative , as the secondary metabolite of the plant-damaging fungi of the genus Fusarium and the type Gibberella fujikuroi is formed.
Fusaric acid has herbicidal , insecticidal and antibacterial effects. It is a wilt toxin for plants (causes premature wilting), but it is only slightly toxic to the animal organism. It inhibits dopamine β-hydroxylase (an enzyme that converts dopamine to noradrenaline ), has antihypertensive activity and influences the membrane properties of cells. It works partially synergistically with other mycotoxins such. B. Deoxynivalenol (DON). Therefore, their role as a mycotoxin is not yet fully understood.
history
Fusaric acid was first identified in 1934 by Teijiro Yabuta at the University of Tokyo as a metabolite of the rice-damaging fungus Gibberella fujikuroi ( Fusarium moniliforme ).
