Abstract
Fumonisins are products of secondary metabolism of Fusarium species, mainly Fusarium verticillioides. These substances are toxic to animals and potentially carcinogenic to humans. To date, 15 genes (FUM) are known to be involved in the biosynthesis of fumonisins, of which FUM1, FUM6 and FUM8 were shown essential to the production of these toxins. However, so far few strains of F. verticil…
