Abstract excerpt
Tetraploid yeast cells lacking BFR1 or overexpressing an essential gene BBP1 produce a novel type of ascus that contains asci instead of spores. We show here that the asci within an ascus likely arise because a/alpha spores undergo a second round of meiosis. Cells depleted of Bbp1p or lacking Bfr...
