The 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. But the MAT ...
Stemphyliumspecies contain a single idiomorph (self-sterile), eitherMAT1-1orMAT1-2, whereas others contain a unique fusion ofMAT1-1andMAT1-2regions (self-fertile)2,39. However, the sexual state has not been identified in most species ofStemphylium. TheMATlocus organization is unknown for mo...
The sequence has been determined of 68897bp of genomic DNA including the expressed mat1 mating-type locus from Schizosaccharomyces pombe h S strain 972. The DNA sequence, located on the long arm of fission yeast chromosome II and contained in two cosmid clones, was analysed to reveal one auto...

We have now isolated one of the mating-type genes mat-P and have used it as a hybridization probe for sequence changes at the mating-type locus. We confirm that the genetic loss suggested for h S is due to deletion and demonstrate that the impairment of switching in h +N and h U is...
MAT locus, became easy and rapid to identify theD. rabieimating types [17]. Com1 was specific to the 3′ flanking regions of the MAT genes, SP21 designed to MAT1-1 and Tail 5 was designed to MAT 1-2 and they amplified an approximate of 700-bp fragment from MAT1-1 isolate, while...

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. MAT alpha and MATa thus contain regions...
The present study, comparing DNA sequences in the DNA region (MAT locus) that controls mating and spore production, found four main mating type genes (MAT1-1-5, MAT1-1-1, MAT1-2-1 and MAT1-2-4) in the self-fertile strain derived from large spores. In contrast, this DNA region ...
Northern blot analysis revealed that transcription of the a -specific gene STE2 and the haploid-specific locus RME1 in these transformants is repressed to the same level as in wild-type MAT a / MAT α cells. We concluded that neither Cys33 nor Cys34 is required for repression of a -...
