abstract：:Efficient mating-type (MT) switching in homothallic strains of Schizosaccharomyces pombe is significantly reduced if they have a mutation in any of the eleven known swi genes. The swi4 mutation causes heterothallic as well as homothallic segregants, both of which have duplications in the MT region. In contrast to homo...
