The mating-type locus ofNeurospora crassa
Journal of Genetics, 1996The mating-type locus regulates choice of mating partner and the formation of mixed-mating-type heterokaryons inNeurospora crassa. These biological activities reflect the effects of the mating-type genes on several distinct biochemical pathways. Some elements of such pathways are probably common to many other fungi.

Mating-Type Locus Control of Cell Identity
2014This chapter addresses how MAT loci is identified from budding ascomycetes to filamentous ascomycetes to basidiomycetes function to specify cell identity. The chapter begins with an introduction to the cell identity determination paradigm established in the budding yeast Saccharomyces cerevisiae.

Rearrangements at the mating type locus in fission yeast
Molecular and General Genetics MGG, 1976Crosses involving the partially defective mating type mutant B102 (functional in conjugation, defective in meiosis) have confirmed the notion that, in Schizosaccharomyces pombe, certain mating type mutations can arise by transposition. A copy of the mat2P segment (specifying + mating type) is transposed and inserted into the mat1M segment (usually ...

Evolution of the Mating-Type Locus: The Basidiomycetes
2014Sexual reproduction is ubiquitous in nature. As the engine that drives genetic diversity, sex accelerates adaptation and removes deleterious mutations. As such, it plays a central role in the origin and success of species. Studies on the major groups within the fungal kingdom have provided significant and wide-ranging contributions on the molecular ...

Isolation and characterisation of the mating-type ( MAT ) locus from Rhynchosporium secalis
Current Genetics, 2003The mating-type ( MAT) genes from Rhynchosporium secalis were isolated using PCR-based methods. Characterisation of the MAT idiomorphs suggests that R. secalis is closely related to the discomycetes Pyrenopeziza brassicae and Tapesia yallundae in terms of sequence and MAT locus gene composition.

Ceratocystidaceae exhibit high levels of recombination at the mating-type (MAT) locus
Fungal Biology, 2018Mating 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). Species in the ascomycete family Ceratocystidaceae have different mating strategies, making them interesting to consider with regards to ...

The genetic instabilities of the mating type locus in fission yeast
Molecular and General Genetics MGG, 1976Certain genetic instabilities of the "mating type locus" in the yeast Schizosaccharomyces pombe are interpreted in terms of transposition: Homothallic strains are characterized by two adjacent mating type genes (mat1-mat2+) with sexually complementary functions. One of these genes (mat2+) is able to duplicate itself, and the duplicated copy maps at the

Heterozygosity at the b mating-type locus attenuates fusion in Ustilago maydis
Current Genetics, 1995Mating and pathogenesis of the corn smut fungus, Ustilago maydis, are controlled by two unlinked mating-type loci, a and b. Yeast-like haploids that differ at both loci are compatible and fuse to establish a pathogenic dikaryon. Mating is assayed in vitro by co-inoculation on culture medium containing activated charcoal; compatible combinations have a ...

Unequal distribution of the mating type ( MAT ) locus idiomorphs in dermatophyte species
Fungal Genetics and Biology, 2018The mating type (MAT) locus is the key regulator of sexual reproduction in fungi. In the dermatophytes and other Ascomycetes this genomic region exists in two distinct forms (idiomorphs) and their balanced presence is a precondition for successful mating in heterothallic fungi.

Mating-type locus structure affects gene expression in unidirectional mating-type switching fungi
Abstract Fungal species are typically either fully self-fertile or self-sterile, but some filamentous ascomycetes can commonly transition from self-fertility to self-sterility through unidirectional mating-type switching. In these fungi, the structure of the mating-type (MAT1) locus governs sexual behaviour: MAT-2 self-fertile individuals ...Frances A. Lane +3 more
