The veA gene positively regulates sterigmatocystin production in Aspergillus nidulans and aflatoxin production in A. parasiticus and A. flavus. Whether veA homologs have a role in regulating secondary metabolism in other fungal genera is unknown. In this study, we examined the role of the veA homolog, FvVE1, on production of two mycotoxin families, fumonisins and fusarins, in the important corn pathogen F. verticillioides. We found that FvVE1 deletion completely suppressed fumonisin production on two natural substrates, corn and rice. Furthermore, our results revealed that FvVE1 is necessary for the expression of the pathway-specific regulatory gene FUM21 and structural genes in the fumonisin biosynthetic gene (FUM) cluster. FvVE1 deletion also blocked production of fusarins. The effects of FvVE1 deletion on the production of these toxins were found to be the same in two separate mating types. Our results strongly suggest that FvVE1 play an important role in regulating mycotoxin production in F. verticillioides.
