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.

The mating-type locus of Chlamydomonas reinhardtii contains highly rearranged DNA sequences

Cell, 1994
The mating-type locus of Chlamydomonas reinhardtii exists as two apparent alleles (mt+ and mt-) that control mating in haploid gametes and sporulation and meiosis in diploid mt+/mt- zygotes. Twelve genes, seven unrelated to life cycle transitions, are tightly linked to mt, suggesting that the locus exerts recombinational suppression.

Novel mating type-dependent transcripts at the mating type locus in Magnaporthe oryzae

Gene, 2007
The mating type locus (MAT1) of Magnaporthe oryzae has similar structural organization to MAT in other ascomycetes and encodes the mating type genes MAT1-1-1 with an alpha-box motif and MAT1-2-1 with an HMG-box motif in the MAT1-1 and MAT1-2 idiomorphs, respectively.

Transcripts at the mating type locus of Cochliobolus heterostrophus

Molecular and General Genetics MGG, 1997
The single mating type locus (MAT) of the heterothallic ascomycete Cochliobolus heterostrophus is composed of a pair of unlike sequences called idiomorphs, each of which encodes one MAT-specific gene (MAT-1 and MAT-2). MAT transcripts were observed in blots of poly(A)+ RNA isolated from cultures grown in minimal medium, but were not detectable after ...

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
