Schizosaccharomyces meiosis.

The group of Prof. Viesturs Simanis (UPSIM – Regulation of cell division) investigated the role of the SIN regulator dma1p in meiosis. They found that although both meiotic divisions occur in the absence of dma1p, asci frequently contain fewer than four spores, which are larger than in wild-type meiosis. These data indicate that dma1p acts in parallel to the leading-edge proteins and septins to assure proper formation for the forespore membrane.
