Project description:Intact nuclei from an asynchronous population of W303 Saccharomyces cerevisiae in log-phase growth were subjected to a 16-minute DNase I digestion (0.1 U/μL) at 37 °C. DNA was then recovered, and single-end Illumina sequencing libraries were prepared using the Crawford DNase-seq method (Song and Crawford, 2010).
Project description:Saccharomyces cerevisiae is an excellent microorganism for industrial succinic acid production, but high succinic acid concentration will inhibit the growth of Saccharomyces cerevisiae then reduce the production of succinic acid. Through analysis the transcriptomic data of Saccharomyces cerevisiae with different genetic backgrounds under different succinic acid stress, we hope to find the response mechanism of Saccharomyces cerevisiae to succinic acid.
Project description:RNA sequencing of Saccharomyces cerevisiae wild type and alanyl-tRNA synthetase mutants grown at 30 degrees and challenged at 37 degrees
Project description:A propolis-resistant Saccharomyces cerevisiae mutant strain was obtained using an evolutionary engineering strategy based on successive batch cultivation under gradually increasing propolis levels. The mutant strain FD 11 was selected at a propolis concentration that the reference strain could not grow at all. Whole-genome transcriptomic analysis of FD11 was performed with respect to its reference strain to determine differences in gene expression levels between the two strains. Saccharomyces cerevisiae
Project description:The conserved Saccharomyces cerevisiae kinase/ATPase Rio1 downregulates rDNA transcription to promote rDNA stability and segregation. To uncover additional roles in transcriptional regulation beyond the rDNA locus we defined the global Rio1 transcriptiome. By NGS we identify 818 differentially expressed genes that are under the transcriptional control of Rio1.
Project description:Snf1 and TORC1 are two global regulators that sense the nutrient availability and regulate the cell growth in yeast Saccharomyces cerevisiae. Here we undertook a systems biology approach to study the effect of deletion of these genes and investigate the interaction between Snf1 and TORC1 in regulation of gene expression and cell metabolism.
Project description:Industrial bioethanol production may involve a low pH environment,improving the tolerance of S. cerevisiae to a low pH environment caused by inorganic acids may be of industrial importance to control bacterial contamination, increase ethanol yield and reduce production cost. Through analysis the transcriptomic data of Saccharomyces cerevisiae with different ploidy under low pH stress, we hope to find the tolerance mechanism of Saccharomyces cerevisiae to low pH.
