Yeast mutants that produce a novel type of ascus containing asci instead of spores.

Genetics - 1 Nov 1996

Xue Z, Shan X, Sinelnikov A, Mélèse T

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 Bfr1p are defective in a number of processes such as nuclear segregation, bud formation, cytokinesis and nuclear spindle...
