Abstract
Meiosis in Saccharomyces cerevisiae requires the induction of a large number of genes whose mRNAs accumulate at specific times during meiotic development. This study addresses the role of mRNA stability in the regulation of meiosis-specific gene expression. Evidence is provided below demonstrating that the levels of meiotic mRNAs are exquisitely regulated by both transcriptional control and RNA turnover. The data show that (i) early meiotic transcripts are extremely unstable when expressed during either vegetative growth or sporulation, and (ii) transcriptional induction, rather than RNA turnover, is the predominant mechanism responsible for meiosis-specific transcript accumulation. When genes encoding the early meiotic mRNAs are fused to other promoters and expressed during vegetative growth, their mRNA half-lives, of under 3 min, are among the shortest known in S. cerevisiae. Since these mRNAs are only twofold more stable when expressed during sporulation, we conclude that developmental regulation of mRNA turnover can be eliminated as a major contributor to meiosis-specific mRNA accumulation. The rapid degradation of the early mRNAs at all stages of the yeast life cycle, however, suggests that a specific RNA degradation system operates to maintain very low basal levels of these transcripts during vegetative growth and after their transient transcriptional induction in meiosis. Studies to identify specific cis-acting elements required for the rapid degradation of early meiotic transcripts support this idea. A series of deletion derivatives of one early meiosis-specific gene, SPO13, indicate that its mRNA contains determinants, located within the coding region, which contribute to the high instability of this transcript. Translation is another component of the degradation mechanism since frameshift and nonsense mutations within the SPO13 mRNA stabilize the transcript.
