(Submitter supplied) In previous temporal studies, we found the anaerobic response was biphasic when cells growing in galactose medium were shifted from aerobiosis to anaerobiosis, consisting of an acute, transitory phase (<60 min) followed by a more chronic but delayed phase (> 1 generation), but largely monophasic (delayed, chronic phase only) when cells were shifted in glucose medium. Gene network and functional analyses revealed the acute phase was comprised of genes associated with the retooling of metabolism (respiro-fermentative to strictly fermentative) and balancing energy supply and demand. more...

(Submitter supplied) The wild-type (grown on galactose or glucose) or msn2/4 mutant (grown on galactose) strains were grown aerobically. At time zero (generation 0) the sparge gas was switched from air to O2-free N2 and samples were harvested after 0 (aerobic control), 0.04, 0.08, 0.19, and 2 generations of anaerobic growth.

(Submitter supplied) In this study, we systematically identified RNAs associated with ribosomes. To identify ribosome associated RNAs, C-terminal ZZ-tagged Rpl16a or Rpl16b, expressed under control of thier native promoter, were affinity purified from whole cell extracts of cultures grown to mid-log phase in minimal medium. Extracts were incubated with immunoglobulin G (IgG) coupled microbeads, washed, and ribosomes were eluted by tobacco etch virus (TEV) protease treatment. more...

(Submitter supplied) The FAR1 gene encodes a large protein, whose major function is inhibition of cyclin-dependent kinase complexes involved in the G1/S transition. It has been proposed that Far1, together with the G1 cyclin Cln3, may be part of a cell sizer mechanism that controls the entry into S phase. A genome-wide transcriptional analysis of FAR1-overexpressing and far1 deleted cells grown in ethanol- or glucose-supplemented minimal media indicates that FAR1 overexpression induces strong transcriptional remodelling, metabolism being the most affected cellular property. more...

(Submitter supplied) We used RNA-seq to monitor mRNA levels of all genes in response to hypoxia of wild-type yeast, S. cerevisiae (strain yMH914 with wildtype HAP1). To gain insights into how gene expression changes over time, cells were subjected to 100% nitrogen gas and collected after 0,5,10,30,60,120,180, and 240 minutes. Total RNA was extracted and mRNAs were enriched by polyA selection. The cDNA was prepared into a sequencing library, multiplexed and single-end sequenced by an Illumina HiSeq 2500 sequencer. more...

(Submitter supplied) Sampangine, a plant-derived alkaloid found in the Annonaceae family, exhibits strong inhibitory activity against the opportunistic fungal pathogens Candida albicans, Cryptococcus neoformans and Aspergillus fumigatus. In the present study, transcriptional profiling experiments coupled with the analysis of mutants were performed in an effort to elucidate its mechanism of action. Using Saccharomyces cerevisiae as a model organism, we show that sampangine produces a transcriptional response indicative of hypoxia, altering the expression of genes known to respond to low oxygen conditions. more...

(Submitter supplied) The capacity of respiring cultures of Saccharomyces cerevisiae to instantaneously switch to fast alcoholic fermentation upon a transfer to anaerobic sugar-excess conditions is a key characteristic of Saccharomyces cerevisiae in many of its industrial applications. This transition was studied by exposing aerobic glucose-limited chemostat cultures grown at a low specific growth rate to two simultaneous perturbations: oxygen depletion and relief of glucose limitation. more...

(Submitter supplied) The Saccharomyces cerevisiae MYO1 gene encodes the myosin type II heavy chain (Myo1p), a protein required for normal cytokinesis in budding yeast. Deletion of the MYO1 gene prevents actomyosin-driven cytokinesis thereby activating an alternative mechanism that involves the synthesis of a remedial septum. Myo1p deficiency in yeast (myo1) also causes the formation of attached cells, abnormal budding patterns, formation of enlarged and elongated cells, increased osmotic sensitivity, delocalized chitin deposition, and increased chitin synthesis. more...
