Mating-type switching in homothallic clones of the fission yeast, Schizosaccharomyces pombe, appears to follow the same route as previously found for "mutations" from homothallism to heterothallic strains. A copy of mat2-P is transposed to and inserted at rnatl, where it functionally replaces the rn

Results of four crosses are presented which indicate that, in Schizosaccharomyces pombe the plus segment of the mating-typing locus is regulated from a central position, in between of the plus and the minus segment. This conclusion is based on the mapping of a plus-restraining entity r, which is rev
The mating type of fission yeast is determined by the mat1 locus on chromosome II. The sequence content of this locus, and hence the mating type, is switched in a strictly regular pattern by transposition from one of two unexpressed mating type sequences. The expressed and the two silent sequences a
