We obtained three Magnaporthe grisea morphological mutants that had the LINE transposon MGL inserted into the ACR1 locus. Sequence analysis revealed that ACR1 is homologous to medA, a developmental regulator of Aspergillus nidulans conidiation. These results demonstrated that MGL elements could transpose and cause insertional mutagenesis in M. grisea.
