Project description:A six array study using total gDNA recovered from two separate cultures of each of three different strains of Saccharomyces cerevisiae (YB-210 or CRB, Y389 or MUSH, and Y2209 or LEP) and two separate cultures of Saccharomyces cerevisiae DBY8268. Each array measures the hybridization of probes tiled across the Saccharomyces cerevisiae genome.
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:Purpose: According to comparative transcriptomes data, the differentially expressed genes within these selected scrambled yeast strains can be digged out and further analyzed, seeking potential targets that were tuned drastically and might improve β-carotene production when modified. Methods: mRNA profiles of two Saccharomyces cerevisiae strains H0, S3 (each named as yJBH000 and yJBH012 in related manuscript) were generated in triplicate using illumina. Sequencing libraries were generated using NEBNext® Ultra™ RNA Library Prep Kit for Illumina® (NEB, USA) and index codes were added to each sample. The library preparations were sequenced on an Illumina Hiseq 4000 platform. 150 bp paired-end reads were generated as raw data. The read counts for each gene in the genome were summarized as processed data. Results: The yJBH012 had an obviously different pattern of global transcription as compared with the control yJBH000. The upregulation of 589 genes and down regulation of 236 genes were observed in this analysis.
