Genome-wide transcriptional analysis of PE-2 strain of Saccharomyces cerevisiae

ABSTRACT: In this study we investigate the molecular physiology of the main S. cerevisiae commercial strain (PE-2) used on Brazilian bioethanol process under two distinct conditions: typical (TF) and flocculated (co-aggregated - FL) fermentation. Transcriptional machinery of PE-2 was assessed by high throughput sequencing-based methods (RNA-seq) during industrial fed-batch fermentations. Data from comparative analysis revealed distinct transcriptional profiles among conditions, characterized mainly by a deep gene repression on FL process.

Genome-wide transcriptional analysis of PE-2 strain of Saccharomyces cerevisiae

Project description:In this study we investigate the molecular physiology of the main S. cerevisiae commercial strain (PE-2) used on Brazilian bioethanol process under two distinct conditions: typical (TF) and flocculated (co-aggregated - FL) fermentation. Transcriptional machinery of PE-2 was assessed by high throughput sequencing-based methods (RNA-seq) during industrial fed-batch fermentations. Data from comparative analysis revealed distinct transcriptional profiles among conditions, characterized mainly by a deep gene repression on FL process. We investigated the transcriptional changes in S. cerevisiae PE-2 strain under industrial fermentation conditions using RNA-seq protocols. We analyzed 13 fermentation time-points where 6 time-points on typical fermentation conditions (TF) and 7 time-points on flocculate conditions(FL). The raw data have been submitted to SRA as SRP014755

Expression data from non sexual flocculation cells of S. pombe

Project description:Deleting ribosomal protein genes caused haploid cells of S. pombe flocculated in full nutrition YEPD medium. We deleted rpl32-1 and rpl32-2 gene respectively and these two mutant cells cultured in YEPD medium flocculated. We used microarrays to detail the global programme of gene expression between non flocculated rpl32-1 deleted and rpl32-2 deleted, compared with the non flocculated cells SPQ-01, and identified distinct classes of up-regulated genes during this process. Yeast cells cultured in YEPD medium in the log phase were selected for RNA extraction and hybridization on Affymetrix microarrays. The rpl32-1 deleted cells were conformed as SD1 and rpl32-2 deleted cells were conformed as SD2. Control cells SPQ-01 were conformed as WT.

Expression data from sexual flocculation cells of S. pombe

Project description:The h+ and h- haploid cells of S. pombe mixtures flocculated and formed diploid cells when cultured in carbon limited YEPME medium. We first cultured S. pombe h+ YHL6381 and h- SPQ-01 cells respectively in YEPD medium and then mixed them at an 1:1 ratio and further cultured in YEPME medium. Sexual flocculation occured. We used microarrays to detail the the global programme of gene expression of flocculated YHL6381 and SPQ-01 mixtures cultured in YEPME, compared with the non flocculated cells mixtures cultured in YEPD, and identified distinct classes of up-regulated genes during this process. We first cultured S. pombe h+ YHL6381 and h- SPQ-01 cells respectively in YEPD medium and then mixed them at an 1:1 ratio and further cultured in a new medium for 90min. The flocculated cells mixtures cultured in YEPME named YSD, while the non flocculated cells mixtures cultured in YEPD named YSM.
