Mutant2

ABSTRACT: Cells in glucose-limited Saccharomyces cerevisiae cultures differentiate into quiescent (Q) and non-quiescent (NQ) fractions prior to entering stationary phase. To identify genes involved in this differentiation, Q and NQ cells from 101 deletion-mutant strains were tested for viability and reproductive capacity. Twenty-one mutants were identified, including 7 that affected reproductive capacity of both cell types. Thirteen affected only Q or NQ cells, indicating significant differentiation of these cell types. doa4 strains, lacking ubiquitin hydrolase, affected viability and reproductive capacity in both cell types. More than 1300 mRNAs differentiating Q and NQ cell fractions were identified by microarray analysis. Gene-ontology analysis of Q-cell mRNAs showed significant increases i
