Occurrence of Fusarium verticillioides and Fusarium musae on banana fruits marketed in Hungary.

Fusarium strains were isolated from rotten banana fruit imported into Hungary from some African and some Neotropical countries. The strains were identified using morphological features, 2-benzoxazolinone tolerance, translation elongation factor (EF-1α) sequences and inter simple sequence repeat (ISSR) analysis. All strains from Africa proved to be F. verticillioides whereas the strains from the Neotropics are Fusarium musae. According to the PCR proof and the fumonisin toxin measurement F. musae strains cannot produce any fumonisins (FB1-4).
