Abstract

Monitoring Meiosis During meiosis, or in yeast sporulation, haploid cells are generated from diploid cells. Brar et al. (p. 552 , published online 22 December) performed a detailed analysis of messenger RNA (mRNA) abundance and protein synthesis over the course of sporulation. The production of most proteins was tightly regulated both at the mRNA level and by translational control. An unexpected complexity was observed as the cell passed through this key developmental transition, including increases in noncanonical translation from upstream regions of known RNA transcripts, which appear to be important in translational control.
