Fot1, a new family of fungal transposable elements

Mol Gen Genet. 1992 Mar;232(1):12-6. doi: 10.1007/BF00299131.


We report here the discovery of a family of transposable elements, which we refer to as Fot1 elements, in the fungal plant pathogen Fusarium oxysporum. The first element was identified as an insertion in the gene encoding nitrate reductase. It is 1928 bp long, has 44 bp inverted terminal repeats, contains a large open reading frame and is flanked by a 2 bp (TA) target site duplication. This element shares significant structural similarities with a class of transposons that includes Tc1 from Caenorhabditis elegans and therefore represents a new class of transposable elements in fungi.
