(Submitter supplied) Sequence variation in regulatory DNA alters gene expression and shapes genetically complex traits. However, the identification of individual, causal regulatory variants is challenging. Here, we used a massively parallel reporter assay to measure the cis-regulatory consequences of 5,832 natural DNA variants in the promoters of 2,503 genes in the yeast Saccharomyces cerevisiae. We identified 451 causal variants, which underlie genetic loci known to affect gene expression. more...

(Submitter supplied) DNA variants that alter gene expression contribute to variation in many phenotypic traits. In particular, trans-acting variants, which are often located on different chromosomes from the genes they affect, are an important source of heritable gene expression variation. However, our knowledge about the identity and mechanism of causal trans-acting variants remains limited. Here, we developed a fine-mapping strategy called CRISPR-Swap and dissected three expression quantitative trait locus (eQTL) hotspots known to alter the expression of multiple genes in trans in the yeast Saccharomyces cerevisiae. more...

(Submitter supplied) In this study, we mapped for the first time differences in transcription binding among individuals and elucidated the genetic basis of such variation. Whole-genome Ste12 binding profiles were determined using ChIP-Seq in pheromone-treated cells of 43 segregants of a cross between two highly diverged yeast strains, YJM789 and S288c as well as the parental lines. We identified extensive Ste12 binding variation among individuals and mapped underlying cis- and trans- acting loci responsible for such variation. more...

(Submitter supplied) Determining the different sources of heritable variation underlying quantitative traits in nature is currently at the forefront of genetic studies. To this end, molecular profiling studies in S. cerevisiae have shown that individual gene expression levels are subject to genetic control and this variation can mediate genetic differences on phenotype. Thus, determining how natural variation influences allele specific expression (ASE) and ultimately complex traits represents a useful tool to determine the mechanisms leading to yeast niche adaptation. more...

(Submitter supplied) The purpose of this experiment was to determine the genes directly regulated by Ste12 in K. lactis. The experiment was performed in a cells to determine if the a-specific genes were bound by Ste12. Ste12 was tagged with c-myc and was immunoprecipitated with a c-myc antibody. Cells were starved in SD media lacking phosphate for 2 hours, then treated with 10µg/mL K. lactis alpha factor for 2 hours before harvesting. more...

(Submitter supplied) Precise gene expression patterns are established by timely and specific binding of transcription factors (TFs) to regulatory sequences. While these events occur in the context of chromatin, our understanding of how TF-nucleosome interplay affects gene expression is highly limited. Here we present a novel assay for high-resolution measurements of both DNA occupancy and gene expression on large-scale libraries of systematically designed regulatory sequences. more...

(Submitter supplied) In a previous study, we identified extensive natural variation in the response to acute ethanol treatment in three yeast strains: a lab strain derived from the commonly used S288c (DBY8268), vineyard isolate M22, and oak soil strain YPS163. Many expression differences persisted across several modules of co-regulated genes, implicating trans-acting systemic differences in ethanol sensing and/or response. more...

(Submitter supplied) The yeast Saccharomyces cerevisiae is able to adapt and in situ detoxify lignocellulose derived inhibitors such as furfural and HMF. The length of lag phase for cell growth in response to the inhibitor challenge has been used to measure tolerance of strain performance. Mechanisms of yeast tolerance at the genome level remain unknown. Using systems biology approache, this study investigated comparative transcriptome profiling, metabolic profiling, cell growth response and gene regulatory interactions of yeast strains and selective gene deletion mutations in response to HMF challenges during the lag phase of growth. more...

(Submitter supplied) The initial step of RNA polymerase II (Pol II) transcription involves a large number of transcription factors and arises at multiple sites within most promoters. TFIIH is an essential, multi-subunit transcription factor that assembles on promoter DNA with Pol II and five other general transcription factors (GTFs) to form a pre-initiation complex (PIC) for basal transcription. During transcription initiation, TFIIH melts promoter DNA through the ATPase activity of its Ssl2 subunit. more...

(Submitter supplied) We performed ChIP-seq of Hsf1 under non heat shock, 5-minute heat shock and 120 minute heat shock conditions. We used the conditional chemical genetics approach known as “anchor away” (AA) to rapidly inactivate Hsf1. We coupled Hsf1-AA to and nascent RNA seq (NAC)-seq to define the genes whose expression depends on Hsf1 during heat shock.

(Submitter supplied) Expression analysis of BY4716(isogenic to S288c) and a wild isolate collected by R. Mortimer. Each strain was grown in culture 6 independent times and RNA from each culture was isolated. Each of these RNA samples was subjected to a dye-swap pair of arrays (except the "RM11" sample, which only got one array). All arrays used the same pool of reference BY4716 sample. In sample titles, "BY" alone signifies the reference sample and all other strings represent independent cultures. more...
