Transcriptomic analysis of gene expression in diosgenin producing yeast strains. Transcriptomic analysis of gene expression in diosgenin producing yeast strains

To detect the true expression patterns of diosgenin (DSG) synthetic genes after pathway engineering as well as investigate the impact of the DSG accumulation on the physiological state of yeast cells, a global analysis of the transcriptomes of DSG producing strains was performed using mRNA sequencing (RNA-Seq). DSG producing strains include LP085-Vc (DSG titer of 8.0 mg/L), LP104-17 (24.6 mg/L), and LP118 (31.4mg/L) were grown in SD media (2% w/v glucose) and cell samples of the 6h and 24h fermentation time points were collected for transcriptome analyses. Overall design: The mRNA profiles of DSG producing strains include LP085-Vc, LP104-17, and LP118.
