Project description:Growth assay in the presence of a toxic chemical (sr7575) that uses the barcoded collections of yeast gene deletions (haploid, diploid, DamP) to identify deletion strains that are hypersensitive to the drug.
Project description:Growth assay in the presence of Selenomethionine that uses the barcoded collections of yeast gene modification (deletion or DamP) to identify strains that are hypersensitive to the presence of the aminoacid.
Project description:The ability to perform complex bioassays in parallel enables experiments otherwise impossible due to throughput and cost constraints. By way of example, highly parallel chemical-genetic screens using pooled collections of thousands of defined Saccharomyces cerevisiae gene deletion strains are feasible because each strain is barcoded with unique DNA sequences. It is, however, time consuming and expensive to individually barcode individual strains. To provide a simple and general method of barcoding yeast collections, we built a set of donor strains, called Barcoders, with unique barcodes that can be systematically transferred to any S. cerevisiae collection. We applied this technology by generating a collection of barcoded DAmP (Decreased Abundance by mRNA Perturbation) loss-of-function strains comprising 87.1% of all essential yeast genes. This test collection validates both the Barcoders and the DAmP collection as useful tools for genome-wide chemical genetic assays.

Project description:We report change in the chromatin contacts upon deletion of ATP-dependent chromatin remodellers (ISW1, ISW2 and CHD1) in Saccharomyces cerevisiae.
Project description:We report change in the nucleosome occupancy and accessibility upon deletion of ATP-dependent chromatin remodellers (ISW1, ISW2 & CHD1) in Saccharomyces cerevisiae.
Project description:We report change in the chromatin contacts at nucleosomal resolution upon deletion of ATP-dependent chromatin remodellers(Isw1,Isw2 and Chd1) in Saccharomyces cerevisiae.
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:To understand the gene expression in Saccharomyces cerevisiae under fermentative and respiraotry conditions, we perfomred the genome-wide gene expression profiling for the log-phase cells of S. cerevisiae wild type, sef1 deletion, and hyperactive SEF1-VP16 mutants under the YPD and YPGly conditions.
