Maintaining two mating types: structure of the mating type locus and its role in heterokaryosis in Podospora anserina. [PDF]
AbstractPseudo-homothallism is a reproductive strategy elected by some fungi producing heterokaryotic sexual spores containing genetically different but sexually compatible nuclei. This lifestyle appears as a compromise between true homothallism (self-fertility with predominant inbreeding) and complete heterothallism (with exclusive outcrossing ...

Sporisorium scitamineum is the causal agent of sugarcane smut, which is one of the most serious constraints to global sugarcane production. S. scitamineum and Ustilago maydis are two closely related smut fungi, that are predicted to harbor similar sexual

Essential genes encoded by the mating-type locus of the human fungal pathogen Cryptococcus neoformans [PDF]
Fungal sexual reproduction is controlled by the mating-type (MAT) locus. In contrast to a majority of species in the phylum Basidiomycota that have tetrapolar mating-type systems, the opportunistic human pathogen Cryptococcus neoformans employs a bipolar

Identification of the first oomycete mating-type locus sequence in the grapevine downy mildew pathogen, Plasmopara viticola [PDF]
Mating types are self-incompatibility systems that promote outcrossing in plants, fungi and oomycetes. Mating-type genes have been widely studied in plants and fungi, but have yet to be identified in oomycetes, eukaryotic organisms closely related to ...

Healing of mat mutations and control of mating type interconversion by the mating type locus in Saccharomyces cerevisiae [PDF]
Homothallic yeasts switch cell types (mating types a and α) at high frequency by changing the alleles of the mating type locus, MAT a and MAT α. We have proposed in the cassette model that yeast cells contain silent MAT a and MAT α blocs ...

Meiotic recombination of sex chromosomes is thought to be repressed in organisms with heterogametic sex determination (e.g. mammalian X/Y chromosomes), due to extensive divergence and chromosomal rearrangements between the two chromosomes.

In heterothallic ascomycetes, mating is controlled by two nonallelic idiomorphs that determine the ‘sex’ of the corresponding strains. We recently discovered mating‐type loci and a sexual life cycle in the penicillin‐producing fungus, Penicillium ...

Recombination hotspots flank the Cryptococcus mating-type locus: implications for the evolution of a fungal sex chromosome. [PDF]
Recombination increases dramatically during meiosis to promote genetic exchange and generate recombinant progeny. Interestingly, meiotic recombination is unevenly distributed throughout genomes, and, as a consequence, genetic and physical map distances ...

Ceratocystidaceae exhibit high levels of recombination at the mating-type (MAT) locus.
Mating is central to many fungal life cycles and is controlled by genes at the mating-type (MAT) locus. These genes determine whether the fungus will be self-sterile (heterothallic) or self-fertile (homothallic).
