MBioFungal 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

Tracing the Origin of the Fungal α1 Domain Places Its Ancestor in the HMG-Box Superfamily: Implication for Fungal Mating-Type Evolution [PDF]
PLoS ONE, 2010 BackgroundFungal mating types in self-incompatible Pezizomycotina are specified by one of two alternate sequences occupying the same locus on corresponding chromosomes.

Differential Gene Expression between Fungal Mating Types Is Associated with Sequence Degeneration [PDF]
Genome Biology and Evolution, 2020 Abstract Degenerative mutations in non-recombining regions, such as in sex chromosomes, may lead to differential expression between alleles if mutations occur stochastically in one or the other allele. Reduced allelic expression due to degeneration has indeed been suggested to occur in various sex-chromosome systems.

eLife, 2022 Sexual reproduction is a ubiquitous, ancient eukaryotic trait. While most sexual organisms have to find a mating partner, species as diverse as animals, plants, and fungi have evolved the ability to reproduce sexually without requiring another individual.

Genetic basis of self-incompatibility in the lichen-forming fungus Lobaria pulmonaria and skewed frequency distribution of mating-type idiomorphs: implications for conservation. [PDF]
PLoS ONE, 2012 Fungal populations that reproduce sexually are likely to be genetically more diverse and have a higher adaptive potential than asexually reproducing populations.

DNA loss at the Ceratocystis fimbriata mating locus results in self-sterility. [PDF]
PLoS ONE, 2014 Fungi have evolved a remarkable diversity of reproductive strategies. Some of these, most notably those of the model fungi, have been well studied but others are poorly understood.

The mating-type chromosome in the filamentous ascomycete Neurospora tetrasperma represents a model for early evolution of sex chromosomes. [PDF]
PLoS Genetics, 2008 We combined gene divergence data, classical genetics, and phylogenetics to study the evolution of the mating-type chromosome in the filamentous ascomycete Neurospora tetrasperma.

Shifting fungal reproductive mode by manipulation of mating type genes: obligatory heterothallism of Gibberella zeae [PDF]
Molecular Microbiology, 2003 SummaryFungi capable of sexual reproduction use heterothallic (self‐sterile) or homothallic (self‐fertile) mating strategies. In most ascomycetes, a single mating type locus, MAT, with two alternative forms (MAT1‐1 and MAT1‐2) called idiomorphs, controls mating ability.

The Cryptococcus neoformans STE11α gene is similar to other fungal mitogen‐activated protein kinase kinase kinase (MAPKKK) genes but is mating type specific [PDF]
Molecular Microbiology, 2001 Partial sequence analysis of the Cryptococcus neoformans MATα mating type locus revealed the presence of a gene with substantial sequence similarity to other fungal mitogen‐activated protein (MAP) kinase kinase kinase (MAPKKK) genes. The C. neoformans gene, designated STE11α, showed the highest degree of similarity to the Neurospora crassa nrc‐1 ...
