Several toxigenic Fusarium species have been shown to be involved in FGM, the most frequently isolated being Fusarium verticillioides , Fusarium andiyazi , Fusarium proliferatum , Fusarium thapsinum , and Fusarium sacchari . The aim of the present study was to provide new insights on the occurrence of toxigenic fungi infecting sorghum cultivated in Hungary and the risk of contamination with mycotoxins. To reach this objective, the presence of toxigenic Fusarium isolates in sorghum samples was investigated; fungal species and capacity to produce mycotoxins were characterised for each isolated Fusarium strain. In a second step, the profile in tocochromanols and carotenoids of the two most widely cultivated sorghum varieties in Hungary was detailed and the effect of the predominant compounds on the biosynthesis of fumonisins and type B trichothecenes was investigated.
