Project description:Transcription profiles of mutant M1 and the control in the absence/presence of 4mM H2O2 M1 is a mutated Saccharomyces cerevisiae strain. It was obtained through transcriptional engineering of general transcription factor TFIIB. Encoded by SUA7, TFIIB is reported to regulate the expression of over 730 genes in Saccharomyces cerevisiae. M1 showed significant growth improvement compared with the control when challenged with 4mM H2O2. It also had resistance towards high osmotic pressure (1.5M NaCl).
Project description:Expression analysis of Saccharomyces cerevisiae TAF5 and taf5 temperature conditional mutants grown at permissive and non-permissive temperature. Investigation of whole genome gene expression level changes in Saccharomyces cerevisae taf5-17, taf5-45, taf5-408 and taf5-10.4 mutants, compared to the wild-type strain. The mutations engineered into the strains confer temperature conditional growth. The mutants analyzed in this study are further described in Layer et. al., 2010. Direct Transactivator-Transcription Factor IID (TFIID) Contacts Drive Yeast Ribosomal Protein Gene Transcription. Journal of Biological Chemistry. A twenty chip study using total RNA recovered from four separate wild-type cultures of Saccharomyces cerevisiae and four separate cultures for each of four taf5 temperature conditional mutants (16 mutant cultures). Each chip measures the expression level of 5,777 genes from Saccharomyces S288C with eight 60-mer probe pairs (PM/MM) per gene, with three-fold technical redundancy.

Project description:Using RNA-Seq, the transcriptomes of saccharomyces cerevisiae wild-type MF02 and UV mutant strain UV02_HG were compared under high sugar conditions. Based on this analysis, we found that different expressions between two strains mainly focus on the transport and modification of proteins and metabolism of carbon
Project description:Transcriptomic study to characterize the interaction of the Penicillium expansum antifungal protein PeAfpA with the the model yeast Saccharomyces cerevisiae. For this, the transcriptome of S. cerevisiae BY4741 strain was compared among samples treated with increasing concentrations of PeAfpA.
Project description:A caffeine-resistant Saccharomyces cerevisiae mutant strain was obtained using an evolutionary engineering strategy based on successive batch cultivation at gradually increasing caffeine levels. The mutant strain Caf905-2 was selected at a caffeine concentration where its reference strain could not grow at all. Whole-genome transcriptomic analysis of Caf905-2 was performed with respect to its reference strain.
Project description:Proteomic analysis of the extracellular matrix of Saccharomyces cerevisiae W303-1A Wt and the isogenic mutant strain gup1Δ during the development of multicellular overlays.
Project description:Investigation of global gene expression changes in Saccharomyces cerevisiae strain NRRL Y-12632 (ATCC® 18824) grown in media made with asbestos mine tailings-laden water compared to the control grown in media made with double distilled water
Project description:We investigated the effect of deletion of BMH1, SPL2 and RRP6 on gene expression in the yeast Saccharomyces cerevisiae. In addition, the effect of 60 min phosphate starvation was studied in the SPL2 deletion mutant as well as in the parental strain BY4741. Finally, the effect of deletion of specific parts of the SPL2 promoter was investigated. Transcriptome analysis was performed by strand-specific RNAseq.
Project description:Transcriptional profiling of ethanol tolerant strains Ets2 and Ets3 comparing control Saccharomyces cerevisiae L3262 with ethanol tolerant strains Ets2 and Ets3, through screening a mutant library of SPT15 of Saccharomyces cerevisiae L3262.
