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: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:ppGpp accumulation caused by ectopic expression of RelA in Saccharomyces cerevisiae gave rise to marked changes in gene expression with both upregulation and downregulation, including changes in mitochondrial gene expression. The most prominent upregulation (38-fold) was detected in the function-unknown hypothetical gene YBR072C-A, followed by many other known stress-responsive genes. ppGpp acuumulation resulted in enhancement of tolerance against various stress stimuli, such as osmotic stress, ethanol, hydrogen peroxide, and high temperature.

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.

As a comparison, another culture of S. cerevisiae expressing Candida albicans Nik1p was treated with 1 M sorbitol to induce osmotic stress response. One culture remained untreated as a control. From all cultures, samples were taken after a duration of 15, 30 and 60 min.

Project description:Timely signaling pathways activation allows cells to survive diverse environmental stress conditions. Mitogen-activated protein kinases (MAPKs) are a highly conserved class of signaling molecules in eukaryotes with essential functions in cellular responses to stress. In Saccharomyces cerevisiae, the role of MAPK Hog1 as a master regulator of the coordinated response to osmotic stress is well understood. However, recent findings suggest that the role of Hog1 may extend beyond canonical osmoadaptation. This study investigates the role of Hog1 in mediating transcriptional responses to acute oxidative and ethanol stress. By harnessing the natural variation present in wild strains of S. cerevisiae, we use gene knockouts, comparative transcriptomics, and survival assays to determine Hog1’s involvement in stress responses beyond osmoadaptation. Our findings demonstrate that Hog1 mediates transcriptional reprogramming for non-osmotic stress response in a strain-dependent manner. Osmospecificity of Hog1 activity was identified in the DBY8268 laboratory strain, while differential gene expression was observed in HOG1 knockouts of all wild strains tested under both oxidative and ethanol stress. Further, our data indicate that the function of Hog1 in the response to non-osmotic stress is distinct from the canonical response, with effects ranging from altered ribosomal protein expression dynamics to altered environmental stress response (ESR) activity. Differences in expression correlate with fitness defects of hog1∆ mutants. These results suggest a generalized role of the Hog1 MAPK in S. cerevisiae, consistent with an evolutionarily generalized function for this kinase, underscoring the importance of genomic diversity for elucidating stress signalling dynamics in yeast.
