Thermotoga maritima transcription during exponential and stationary phase growth on 1 and 5 g/l yeast extract

ABSTRACT: Although proteins and peptides encoded in small open reading frames (ORFs < 100 AA) in microbial genomes can play critical roles as toxins, bacteriocins, transcriptional regulators, signaling molecules, and chaperones, many such ORFs remain annotated as M-bM-^@M-^\hypothetical proteinsM-bM-^@M-^]. In the genome of the hyperthermophilic bacterium, Thermotoga maritima, nearly 2/3 of the 167 small ORFs have no known function. As a strategy for investigating the potential significance of specific small ORFs, growth conditions that could trigger the expression of genes encoding small ORFs were sought. A defined medium supplemented with either 1 or 5 g/L yeast extract was used to track transcriptional response during the transition from exponential to stationary phase. RNA derived from exponential (1E) and stationary (1S) phase cultures grown on 1 g/l yeast extract was compared to RNA derived from exponential (5E) and stationary (5S) phase cultures grown on 5 g/l yeast extract using a four-slide loop design.

Project description:Background: Global patterns of gene expression of Escherichia coli K-12 during growth transitions have been deeply investigated, however, comparable studies of E. coli O157:H7 have not been explored, particularly with respect to factors regulating virulence genes and genomic islands specific to this pathogen. To examine the impact of growth phase on the dynamics of the transcriptome, O157:H7 Sakai strain was cultured in MOPS minimal media (0.1% glucose), RNA harvested at 10 time points from early exponential to full stationary phase, and relative gene expression was measured by co-hybridization on high-density DNA microarrays. Results: Analysis of variance (R/MAANOVA, Fs test) identified 442 (36%) of 1239 O157-specific ORFs and 2110 (59%) of 3647 backbone ORFs that changed in expression significantly over time. QT cluster analysis placed 2468 of the 2552 significant ORFs into 12 groups; each group representing a distinct expression pattern. ORFs from the largest cluster (n=1078) decreased in expression from late exponential to early stationary phase: most of these ORFs are involved in functions associated with steady state growth. Also represented in this cluster are ORFs of the TAI island, encoding tellurite resistance and urease activity, which decreased ~4-fold and most ORFs of the LEE island, which decreased ~2-fold by early stationary phase. ORFs encoding proteins secreted via the LEE encoded type III secretion system, such as tccP and espJ, also decreased in expression from exponential to stationary phase. Three of the clusters (n=154) comprised genes that are transiently upregulated at the transition into stationary phase and included genes involved in nutrient scavenging. Upregulated genes with an increase in mRNA levels from late exponential to early stationary phase belonged to one cluster (n=923) which includes genes involved in stress responses (e.g. gadAB, osmBC, and dps). These transcript levels remained relatively high for >3h in stationary phase. The Shiga toxin genes (stx1AB and stx2B) were significantly induced after transition into stationary phase. Conclusions: Expression of 307 O157-specific ORFs was modulated in a growth dependent manner. These results provide a baseline transcriptional profile that can be compared to patterns of gene expression of this important foodborne pathogen under adverse environmental conditions.

Project description:Escherichia coli O157:H7 has caused serious outbreaks of foodborne illness via transmission in a variety of food vehicles, including unpasteurized apple juice, dried salami, and spinach. To understand how this pathogen responds to the multiple stresses of the food environment, we compared global transcription patterns after exposure to apple juice. Transcriptomes of mid-exponential and stationary phase cells were evaluated after 10 minutes in model apple juice (pH3.5) using microarrays probing 4,886 ORFs. Significant changes in gene expression were determined using R/MAANOVA and the Fs test. A total of 331 ORFs were significantly induced upon exposure of cells to model apple juice and included genes involved in the acid and osmotic stress responses as well as the oxidative stress response and envelope stress. Genes involved in the acid and osmotic stress responses, including asr, osmC, osmB, and osmY were significantly induced in response to model apple juice. Genes involved in the envelope stress response, known to be controlled by CpxR (cpxP, degP, and htpX), were significantly induced 2 to 15 fold upon exposure to apple juice, independent of growth phase. Inactivation of CpxRA resulted in a significant decrease in survival of O157:H7 in model apple juice compared to the isogenic parent strain. Of the 331 ORFs induced in model apple juice, 104 are O157-specific ORFs, including those encoding type three secretion effectors espJ, espB, espM2, espL3 and espZ. By elucidating the response of O157:H7 to acidic foods, we hope to gain insights into how this pathogen is able to survive in food matrices and how exposure to foods affects subsequent transmission and virulence. Keywords: stress The results are based on O157:H7 Sakai exponential and stationary phase cultures grown in MOPS minimal medium and then exposed to model apple juice (pH 3.5, 37C) for 10 minutes. Differences in transcript levels were determined using a mixed model ANOVA in R/MAANOVA which tested for significant differences due to growth phase (exponential or stationary), treatment (MOPS or MAJ) and the interaction of these two factors using the following linear model: array+dye+sample (biological replicate)+ phase+treatment+phase*treatment. We incorporated the dye-swaps among the biological replicates.

Project description:Limited systems-level understanding of oil synthesis in wild oleaginous algae has hindered the development of microalgal feedstock. Nannochloropsis is a small unicellular microalgae widely distributed in oceans and fresh water. In many large-scale and pilot-scale outdoor cultivation facilities, Nannochloropsis strains have been found to be capable of robust growth when supplied with flue gases, naturally accumulating large quantities of oils in a stationary phase, and exhibiting resistance to environmental contaminants. The rich genomic resources, compact genomes, resistance to foreign DNA invasion, wide ecological adaptation, large collections of natural strains and the demonstrated ability to grow on a large scale suggested Nannochloropsis can serve as research models and platform strains for economical and scalable photosynthetic production of fuels and chemicals. To untangle the intricate genome-wide networks underlying the robust biomass accumulation and oil production in Nannochloropsis, we applied high-throughput mRNA-sequencing and reconstructed the structure and dynamics of the genome-wide functional network underlying robust microalgal triacylglycerol (TAG) production in Nannochloropsis oceanica, by tracking the genome-wide, single-base-resolutiontranscript change for the complete time-courses of nitrogen-depletion-induced TAG synthesis. Nannochloropsis oceanica IMET1 cells were grown in liquid cultures under continuous light (approximately 50 M-BM-5mol photons m-2 s-1) at 25M-bM-^DM-^C and aerated by bubbling with a mixture of 1.5% CO2 in air. Mid-logarithmic phase algal cells were collected and washed three times with axenic seawater. Equal numbers of cells were re-inoculated in nitrogen replete medium (Control condition or C, i.e. N+) and nitrogen deprived medium (N deficiency or N, i.e. N-) with 50M-BM-5mol m-2 s-1 light intensity, respectively. Cell aliquots were collected for RNA isolation after being transferred to the designated conditions for 3h, 4h, 6h, 12h, 24h and 48h. Three biological replicates of algal cultures were established under each of the above M-bM-^@M-^\CM-bM-^@M-^] (i.e. N+) and M-bM-^@M-^\NM-bM-^@M-^] (i.e. N-) conditions, respectively. In total, 36 samples collected at six time points (3h,4h,6h,12h,24h and 48h) were used for mRNA-Seq library preparation and then submitted to Illumina HiSeq 2000 for sequencing.
