The genetic instabilities of the mating type locus in fission yeast

Molecular and General Genetics MGG, 1976
Certain 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

Ceratocystidaceae exhibit high levels of recombination at the mating-type (MAT) locus

Fungal Biology, 2018
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). Species in the ascomycete family Ceratocystidaceae have different mating strategies, making them interesting to consider with regards to ...

The function of the mating-type locus in filamentous Ascomycetes

1965
Heterothallism in the Euascomycetes has been of interest to mycologists ever since its discovery by Dodge (1920) in Ascobolus magnificus. In this classic paper, he showed that heterothallism in this species is a genetically determined condition in which the two mating groups (A, a) are determined by the two alleles (A, a) at a single locus.

Chromosomal heteromorphism linked to the mating type locus of the oomycete Phytophthora infestans

Molecular and General Genetics MGG, 1996
The mating type locus of the oomycete, Phytophthora infestans, is embedded in a region of DNA that displays distorted and non-Mendelian segregation. By using DNA probes linked to the mating type locus to genetically and physically characterize that region, a large zone of chromosomal heteromorphism was detected.

Regulation of cell type in yeast by the mating-type locus

Trends in Biochemical Sciences, 1986
Abstract Yeast developmental pathways are regulated by combinations of gene regulatory proteins specified by the mating-type locus ( MAT ), at least one of which is a DNA-binding protein. Rapid progress is being made in understanding how these proteins work. The MAT gene products share homology with the homeobox, a sequence contained in the homeotic

Heterozygosity at the b mating-type locus attenuates fusion in Ustilago maydis

Current Genetics, 1995
Mating 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 ...

Identification of sites required for repression of a silent mating type locus in yeast

Journal of Molecular Biology, 1984
There are three loci in the yeast Saccharomyces, each containing one of two possible genetic elements that can determine cell type. At one of these loci, MAT, this information is expressed to establish the mating type of the cell. At the other two loci, HML and HMR, this same information is phenotypically and transcriptionally silent, even though a ...

Characterisation of the mating-type locus of the plant pathogenic ascomycete Leptosphaeria maculans

Current Genetics, 2003
The nucleotide sequences of regions containing the mating-type locus of the plant-pathogenic ascomycete Leptosphaeria maculans are described. The MAT1-1 gene is 1,368 bp, encoding a predicted protein of 441 amino acids, with a 45-bp intron. The MAT1-2 gene is 1,246 bp, encoding a predicted protein of 397 amino acids, with a 55-bp intron.

Specificity at the b mating type locus of ustilago maydis

2009
The ability to discriminate between self and nonself allows Ustilago maydis to maintain genetic diversity through a multiallelic mating type system governed by the b locus. There are approximately 25 different alleles of the b locus and a given individual is incompatible with "self, but compatible with all "nonself mating types. The b locus consists of
