Strand-Specific RNA Sequencing for wild type and Drpd3 yeast entering quiescence [RNA-seq]

Strand-specific RNA sequencing was performed on wild type yeast in log phase, after diauxic shift, and after entry into quiescence with incorporation of external ERCC RNA spike-in controls to account for global changes in RNA abundance. We find that RNA profiles undergo at least two transitions: 1) From log-to-diauxic shift where stress response genes are induced and translational machinery is massively repressed. 2) From diauxic shift-to-quiescence, where global transcript abundance is repressed 15-fold. The transition from diauxic shift to quiescence was found to require Rpd3, as deletion of Rpd3 prevented the global repression of the transcriptome after the diauxic shift. Overall design: Strand-specific RNA sequencing was carried out in biological replicate with external controls then transcript abundance was normalized to reflect RNA content per cell.
