Summary
The formation of fertile crosses (when possible), nuclear DNA relatedness and sequence comparison of select region of a large subunit (25S) ribosomal RNA are suitable methods for taxonomic determination and a phylogenetic classification of the strains. These genetic methods can also be used to predict whichFusarium strains produce mycotoxins since the genetic placement of the strains has been shown to have a good correlation with mycotoxin production ability at the species level.
