Natural variation in the consequences of gene overexpression during osmotic stress [RNA-Seq]
We used RNA-Seq to measure transcript abundance in 4 Saccharomyces cerevisiae strains (BY4743, BC187, NCYC3290, and YPS128) from a diverse range of genetic lineages when growing in rich media (YPD) with 0.7M NaCl to characterize differential expression across strains in response to osmotic and ionic stress. Overall design: RNA-seq and transcriptome analysis of 4 strains (BY4743, BC187, NCYC3290, and YPS128) that were grown in YPD+ 0.7M NaCl. For each strain, 3 samples were collected: T0 (unstressed cells), T30 (30 mins after cells placed in 0.7M NaCl), and T3h (3 hours after cells placed in NaCl). These strains were collected in 3 biological replicates. The library for sample YPS128 Rep 3 T30 failed so this sample is missing and there are a total of 35 samples in the dataset.
