Continuous passaging in vitro can lead to the accumulation of changes in DNA sequence that potentially affect the properties of microbes, making them different from the original isolates. The identification of such genetic alterations is rare in fungi. A set of insertional mutants in the plant pathogenic fungus Leptosphaeria maculans, all derived from the same transformation experiment, had independent Agrobacterium T-DNA insertions and reduced pathogenicity on canola (Brassica napus). None of the insertions co-segregated in progeny
