Isozyme variation among biological species in the Gibberella fujikuroi species complex (Fusarium section Liseola)
Article Abstract:
The different phenotypes of isozymes for 101 strains of Gibberella fujikuroi and two strains of G. nygamai were investigated by isolation and resolution methods. Six enzymes were monomorphic across six of the mating populations while eight enzymes were polymorphic within at least one of the mating populations. The C and D mating populations showed high similarity, while the E population was the least similar to the other populations. Isozyme data revealed that certain biological species share the same phenotypes but are reproductively isolated from one another.

Duckling toxicity and the production of fumonisin and moniliformin by isolates in the A and F mating populations of Gibberella fujikuroi (Fusarium moniliforme)
Article Abstract:
The A and F mating populations of Gibberella fujikuroi exhibit no difference in their toxicity to ducklings. Their ability to produce fumonisins (FUMs) and moniliformin (MON) are however, different. Few members of the F mating population produce FUMs while most of the A mating populations produce FUMs. The ability to produce MON occurs in only a few of the A mating populations, though most F mating populations produce MON. Both the mating populations probably produce other metabolites that are toxic to ducklings.

Beauvericin production by Fusarium species
Article Abstract:
Beauvericin secretion has been measured in 94 isolates belonging to 25 Fusarium taxa. Beauvericin is a cyclohexadepsipeptide mycotoxin with insecticidal qualities and induces apoptosis in mammalian cells. It is found naturally on corn and corn-based foods infection by Fusarium. Results show that beauvericin is produced by many Fusarium species such as F. acuminatum, F. anthophilum and F. avenaceum. There is also evidence that beauvericin contaminates other cereals besides corn.
