FIG. 7.

Meiotic divisions in the grr1Δ mutant. (A) Mid-log-phase cultures of the wild type (WT) and the grr1Δ mutant (SH1970 and SH1752, respectively) were transferred to Sp or Sp+0.5 medium. Samples were removed from these cultures at the indicated times (0 to 36 h) and analyzed for the meiosis I nuclear division (fraction of cells in the culture that are in binucleate or later stages of meiosis). (B) The same samples as shown in panel A were assayed for meiosis II nuclear division (fraction of cells in the culture that are in tetranucleate or later stages of meiosis).
