Project description:Comparative genomic hybridization in traditional fermentative Saccharomyces cerevisiae yeasts
| PRJNA197425 | ENA
Project description:We study the genetics, including microarray karyotyping using comparative genomic hybridization, to explore global changes in the genomic DNA of seven S. cerevisiae strains related to traditional fermentations of very different sources comparing to the sequenced S. cerevisiae laboratory strain (S288C). Our final goal is to determine the adaptive evolution of properties of biotechnological interest in Saccharomyces yeasts. Many copy number variations (CNVs) were observed, especially in genes associated to subtelomeric regions and transposon elements. Among the fermentation strains, differential CNV was observed in genes related to sugar transport and metabolism. An outstanding example of diverse CNV is the gen PUT1, involved in proline assimilation, which correlated with the adaptation of the strains to the presence of this nitrogen source in the media.

Project description:Reprogramming a non-methylotrophic industrial host, such as Saccharomyces cerevisiae, to a synthetic methylotroph reprents a huge challenge due to the complex regulation in yeast. Through TMC strategy together with ALE strategy, we completed a strict synthetic methylotrophic yeast that could use methanol as the sole carbon source. However, how cells respond to methanol and remodel cellular metabolic network on methanol were not clear. Therefore, genome-scale transcriptional analysis was performed to unravel the cellular reprograming mechanisms underlying the improved growth phenotype.

Seven S. cerevisiae strains were obtained from natural environments and different fermentation processes. The S. cerevisiae strain S288C was used as a control for microarray hybridizations. All experiments were performed using duplicate arrays, and Cy5-dCTP and Cy3-dCTP dye-swap assays were performed to reduce dye-specific bias.

Project description:Background: Recent studies have demonstrated that antisense transcription is pervasive in budding yeasts and is conserved between Saccharomyces cerevisiae and S. paradoxus. While studies have examined antisense transcripts of S. cerevisiae for inverse transcription in stationary phase and stress conditions, there is a lack of comprehensive analysis of the conditional specific evolutionary characteristics of antisense transcription between yeasts. Here we attempt to decipher the evolutionary relationship of antisense transcription of S. cerevisiae and S. paradoxus cultured in mid log, early stationary phase, and heat shock conditions. Results: Massively parallel sequencing of sequence strand-specific cDNA library was performed from RNA isolated from S. cerevisiae and S. paradoxus cells at mid log, stationary phase and heat shock conditions. We performed this analysis using a stringent set of sense ORF transcripts and non-coding antisense transcripts that were expressed in all the three conditions, as well as in both species. We found the divergence of the condition specific anti-sense transcription levels is higher than that in condition specific sense transcription levels, suggesting that antisense transcription played a potential role in adapting to different conditions. Furthermore, 43% of sense-antisense pairs demonstrated inverse transcription in either stationary phase or heat shock conditions relative to the mid log conditions. In addition, a large part of sense-antisense pairs (67%), which demonstrated inverse transcription, were highly conserved between the two species. Our results were also concordant with known functional analyses from previous studies and with the evidence from mechanistic experiments of role of individual genes. Conclusions: This study provides a comprehensive picture of the role of antisense transcription mediating sense transcription in different conditions across yeast species. We can conclude from our findings that antisense regulation could act like an on-off switch on sense regulation in different conditions.
