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:Here we used mass spectrometry-based proteomics technology to explore SEPs with potential cellular stress function in Saccharomyces cerevisiae. Microproteins with unique peptides were identified under six culture conditions: normal, oxidation, starvation, UV radiation, heat shock, and heat shock with starvation.

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.

Project description:We present microbial Drop-seq or mDrop-seq, a high-throughput scRNA-seq technique that is used on two yeast species, Saccharomyces cerevisiae, a popular model organism and Candida albicans, a common opportunistic pathogen. We benchmarked mDrop-seq for sensitivity and specificity and used it to profile 35,109 S. cerevisiae cells to detect variation in mRNA levels between them. As a proof of concept, we quantified expression differences in heat-shocked S. cerevisiae using mDrop-seq. We detected differential activation of stress response genes within a seemingly homogenous population of S. cerevisiae under heat-shock. We also applied mDrop-seq to C. albicans cells, a polymorphic and clinically relevant yeast species with thicker cell wall compared to S. cerevisiae. Single cell transcriptomes in 39,705 C. albicans cells was characterized using mDrop-seq under different conditions, including exposure to fluconazole, a common anti-fungal drug.

Project description:Fungal group III histidine kinases are the molecular targets of some classes of fungicides. In contrast to the yeast Saccharomyces cerevisiae, the fungal pathogen Candida albicans possesses a group III histidine kinase, CaNik1p, also called Cos1p. To investigate the function of CaNIK1, the gene was expressed in S. cerevisiae. The transformants became susceptible to antifungal compounds to which the wild-type strain is resistant. The susceptibility was related to the activation of the MAP kinase Hog1p of the osmotic stress response pathway. Gene expression analysis revealed a strong overlap of the responses to osmotic stress and to fludioxonil at early time points. While the response to fludioxonil persisted, the response to osmotic stress was diminished with time.

Project description:This study explores the connection between changes in gene expression and the genes that determine strain survival during suspension culture, using the model eukaryotic organism, Saccharomyces cerevisiae. The Saccharomyces cerevisiae homozygous diploid deletion pool, and the BY4743 parental strain were grown for 18 hours in a rotating wall vessel, a suspension culture device optimized to minimize the delivered shear. In addition to the reduced shear conditions, the rotating wall vessels were also placed in a static position or in a shaker in order to change the amount of shear stress on the cells.

Project description:In the yeast Saccharomyces cerevisiae, accumulation of misfolded proteins in the endoplasmic reticulum (ER) causes ER stress and activates the unfolded protein response (UPR) mediated by Hac1p, whereas the heat shock response (HSR) mediated by Hsf1p mainly regulates cytosolic processes and protects the cell from different stresses. In this study, we find that a constitutive activation of the HSR by over-expression of a mutant HSF1 gene could relieve ER stress in both wild type and hac1delta UPR-deficient cells. We studied the genome-wide transcriptional response in order to identify regulatory mechanisms that govern the interplay between UPR and HSR responses. Interestingly, we find that the regulation of ER stress via HSR is mainly through facilitation of protein folding and secretion and not via the induction of Rpn4-dependent proteasomal activity. Four Saccharomyces cerevisiae strains, WT, WT(hsf1), hac1delta and hac1delta(hsf1), were grown in SD-URA medium and treated with 2.5 mM DTT. After two hours induction, samples were taken for RNA extraction and hybridization on Affymetrix microarrays. Biological triplicates were applied.
