Transcription profiling of Saccharomyces cerevisiae under serial stresses

ABSTRACT: S. cerevisae cells were exposed to different series of mild stresses. Stress type include heat shock, oxidative and osmotic stresses. Microarrays were used to follow the genome-wide transcriptional response to the stresses and to identify genes that can underlie the cross protection phenotype between heat shock and oxidative stress. Experiment Overall Design: Cell sample at different time points after stress application were used for RNA extraction and hybridization on Affymetrix microarrays.

Natural habitats of some microorganisms may fluctuate erratically, whereas others, which are more predictable, offer the opportunity to prepare in advance for the next environmental change. In analogy to classical Pavlovian conditioning, microorganisms may have evolved to anticipate environmental stimuli by adapting to their temporal order of appearance. Here we present evidence for environmental change anticipation in two model microorganisms, Escherichia coli and Saccharomyces cerevisiae. We s ...[more]

Project description:Dinoflagellates have evolved a nuclear organization unlike that of any other eukaryotic group. Recent studies find a predominance of post-transcriptional control of dinoflagellate gene expression. This study investigated regulation of the environmental stress response in the red tide dinoflagellate, Karenia brevis using an Agilent custom oligonucleotide microarray. K. brevis cultures were exposed to 5°C or 10°C heat shock, or three different sources of oxidative stress: 60 µM H2O2, 10 mM NaNO2, or 12 µM PbCl2 over acute time courses. Ribosomal genes, genes involved in RNA processing, translation, and chaperones were among the classes of genes consistently downregulated across treatments, although within these functional classes the same genes did not always respond to different stressors. Genes involved in the photosystem and mitochondrial and chloroplast ATP generation dominated the down-regulated genes. Heat shock and oxidative stress response genes were not induced under any treatment, even under conditions that resulted in decreased viability. We subsequently identified the presence of a trans-spliced leader sequence on many stress response gene transcripts, which suggests that they may be transcribed constitutively and their expression regulated at the level of translation. Cultures of were grown to mid-log phase. For each treatment, five replicate untreated control cultures and five replicate treated cultures were harvested at several time points following treatment. The following time courses were used: 5°C heat shock - 5, 15, 30, 60, and 240 min; 10°C heat shock - 60 min; 60 µM H2O2 - 5, 15, 30, 60, and 240 min; 10 mM NaNO2 -1, 4, and 7 hours; 12 µM PbCl2 -1, 4, and 7 hours. For each treatment, RNA was pooled from the controls and treated cultures at each timepoint. Two color arrays were then run comparing each the transcriptome at timepoint with the pooled control for that treatment. A technical dye swap array was run at each timepoint.

Project description:Rice blast is the most threatening disease to cultivated rice worldwide. Magnaporthe oryzae, its causal agent is likely to encounter environmental challenges during invasive growth in the host plants that require shifts in gene expression to establish a compatible interaction. Here, we tested the hypothesis that M. oryzae have similar gene expression patterns in planta, versus during in vitro stresses. Gene expression data was collected from in vitro experiments of heat shock, oxidative burst, and three different types of nutrient starvation. These data were compared to fungal gene expression during the invasive growth phase in compatible interactions on two grass hosts, rice and barley. We have identified 4,973 differentially expressed genes, from which 1,909 genes showed similar regulation patterns between at least one of the in vitro stresses and rice and/or barley. Hierarchical clustering of these 1,909 genes showed three major clusters in which growth in planta conditions closely grouped with the starving nutrient conditions. Out of these 1,909 genes, 55 and 129 genes were induced and repressed in all seven treatments, respectively. The functional categorization of those 55 induced genes revealed that most of them are either related to carbon metabolism, membrane proteins, or are involved in oxidoreduction reactions. The 129 repressed genes are putatively involved in vesicle trafficking, signal transduction, nitrogen metabolism, or molecular transport. These findings indicated that M. oryzae is likely coping with nutrient deprived environments in its hosts during the invasive growth stage about 72 hours post-inoculation, and not as much with host defense responses, or a temperature stress. Eight M. oryzae treatments: mycelia grown in liquid complete medium (set as the control); 72 hours post-incoulation (hpi) in rice leaves; 72 hours post-incoulation in barley leaves; mycelia under heat shock; mycelia under oxidative stress; mycelia under minimal medium; mycelia under nitrogen starvation; mycelia under carbon starvation. Three biological replicates had their total RNA pulled after RNA extraction. Dye-swaps used as technical replicates.
