Presence and expression of the mating type locus in Paracoccidioides brasiliensis isolates

Fungal Genetics and Biology, 2010
Paracoccidioides brasiliensis has been classified in the phylum Ascomycota, order Onygenales, family Ajellomycetaceae, even in the absence of a known sexual cycle or mating system. The objective of this work was to determine the presence of the mating type locus in 71 P. brasiliensis isolates from various sources. A PCR assay using specific primers for

Homology and non-homology at the yeast mating type locus

Nature, 1981
Four mutations of the alpha mating type locus of Saccharomyces cerevisiae have been analysed to determine their relationship to the a mating type locus. Mat alpha+ recombinations are produced by mat alpha 2-/MAT but not by mat alpha 1-/MATa diploids.

In vitro mutation analysis of the mating-type locus in yeast

Cell, 1981
The mating-type locus (MAT) of Saccharomyces cerevisiae is a complex locus that codes for the regulators of cell type. Two unique messages are transcribed from each MAT allele. Using the in vitro mutagenesis technique whereby synthetic oligonucleotides containing restriction sites (linkers) were inserted into plasmids, we have constructed a series of ...

Transcription and regulatory signals at the mating type locus in yeast

Cell, 1984
The mating type locus with two alleles (MATa and MAT alpha) determines cell type in yeast by activating and repressing sets of cell-type-specific genes. The two genes at MAT alpha, alpha 1 and alpha 2, are transcribed divergently from a central promoter region.

Dominance at a Fungus Mating Type Locus

Nature New Biology, 1972
THE action of the two alleles which control mating type in fungi with bipolar heterothallism is uncertain. A diffusible oligopeptide, produced by the α mating type of Saccharomyces cerevisiae, blocks division and induces copulatory processes in cells of a mating type2,3 and in some yeasts the mating type locus may be induced to mutate by other genes in

Evolution of the Mating-Type Locus: The Basidiomycetes

2014
Sexual 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 ...

Rearrangements at the mating type locus in fission yeast

Molecular and General Genetics MGG, 1976
Crosses 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 ...

The mating-type locus ofNeurospora crassa

Journal of Genetics, 1996
The 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

2014
This 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.

A SEARCH FOR COMPLEXITY AT THE MATING-TYPE LOCUS OFNEUROSPORA CRASSA

Canadian Journal of Genetics and Cytology, 1973
Evidence for complexity at the mating-type locus of Neurospora crassa was sought by selecting recombinants between closely linked markers on either side. All recombinants were tested for crossing ability, to test the hypothesis that the two mating-type alleles are actually closely linked self-sterile mutants; such tests should also detect subunits ...
