Abstract

Sex in fungi is regulated by highly dissimilar mating type loci named idiomorphs. The genus Fusarium harbours both sexual as well as esexual species and each appears to contain one or the other idiomorph. The structure of these loci is highly conserved, suggesting a cryptic sexual cycle in these socalled asexual species. Alternatively, idiomorphs could regulate additional hitherto unrecognized biological processes. Such processes could be elucidated by expression profiling using mutants disrupted in their mating type loci.
