Use of protoplast fusion test to establish the status of mycotoxin genes in an edible Fusarium

The food-acceptable strain A-3/5 of Fusarium graminearum contains a genetic element which can elicit expression of the genes for mycotoxin production in the "lazy" non-producing variant of a zearalenone-producing strain. The failure of A-3/5 itself to produce this toxin is therefore plausi...

Description
Summary:The food-acceptable strain A-3/5 of Fusarium graminearum contains a genetic element which can elicit expression of the genes for mycotoxin production in the "lazy" non-producing variant of a zearalenone-producing strain. The failure of A-3/5 itself to produce this toxin is therefore plausibly explained by lack of the pathway genes rather than by failure to express them.
