| Resumo: |
In this study a total of 16 Fusarium verticillioides strains isolated from corn feed samples were characterized by fumonisin (FB) production and random amplified polymorphic DNA (RAPD). All the strains produced FB1 and FB2 with levels ranging from 2.41 to 3996.36 µg/g, and from 1.18 to 1209.91 µg/g, respectively. From the 16 F. verticillioides strains, four were identified as low (3.59 to 1289.84 µg/g), eight as intermediate (>1289.84 to 3772.44 µg/g) and four strains as high (>3772.44 µg/g) fumonisin producers. From the total of 105 loci amplified, 60 (57.14%) were polymorphic. RAPD analysis showed very similar patterns among low, moderate and high fumonisin-producing strains. Although RAPD markers were capable of discriminating the different F. verticillioides strains, there was no clear association between these makers and fumonisin production.
