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 transp

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
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
