One of the greatest impediments to the study of toxigenic fusaria has been incorrect and confused application of species names to Fusarium isolates. To aid in this, we have created FUSARIUM-SEQ v.1.0, a publicly available sequence database of partial translation elongation factor 1-alpha (TEF) sequences, representing much of the known diversity of the genus.

Users can generate sequences using primers that are conserved across the genus, and use the sequence as a query to BLAST the database, or in a phylogenetic analysis. Sequences are now available for most known Fusarium species, with excellent representation of the Gibberella fujikuroi species complex, Type-B trichothecene producers, Fusarium oxysporum and F. solani species complexes, and correct identification to a known species in these groups often can be performed using this gene region alone.

This growing database will contain only vouchered sequences attached to publicly available cultures.
