Project description:Transcriptome analyses of the Escherichia coli cells acquired in the thermal adaptive evolution (Kishimoto et al, 2010, PLoS Genet) were performed. The ancestor strain (Anc) and the evolved strains (41B, 43B, 45L and 37L) were analyzed. The cells exponetially growing at the regular (37ºC) and/or evolutionary (41~45ºC) temperatures and in response to heat shock at 45ºC were collected for microarray analyses. Multiple transcriptome analyses identified the specific evolutionary direction and bias for thermal adaptation.

Project description:Two E. coli genotypes (type_II and type_III) that showing a mutation either within rpoH or upstream of groESL were isolated in the thermal adaptative evolution. Transcriptome analyses of the two genotypes exponentially growing at both regular and high temperatures were performed.

Project description:Thermal history plays a role in the response of corals to subsequent heat stress. Prior heat stress can have a profound impact on later thermal tolerance, but the mechanism for this plasticity is not clear. The understanding of gene expression changes behind physiological acclimatization is critical in forecasts of coral health in impending climate change scenarios. Acropora millepora fragments were preconditioned to sublethal bleaching threshold stress for a period of 10 days; this prestress conferred bleaching resistance in subsequent thermal challenge, in which non-preconditioned coral bleached. Using microarrays, we analyze the transcriptomes of the coral host, comparing the bleaching-resistant preconditioned treatment to non-preconditioned and control treatments.

Project description:Here, we investigate the genetic mechanisms that underlie thermal specialization of closely-related vibrios isolated from coastal water at the Beaufort Inlet (Beaufort, NC, USA). This location experiences large seasonal temperature fluctuations (annual range of ~20°C), and a clear seasonal shift in vibrio diversity has been observed (Yung et al. 2015). This previous study suggested that the mechanisms of thermal adaptation apparently differ based on evolutionary timescale: shifts in the temperature of maximal growth occur between deeply branching clades but the shape of the thermal performance curve changes on shorter time scales (Yung et al. 2015). The observed thermal specialization in vibrio populations over relatively short evolutionary time scales indicates that few genes or cellular processes may contribute to the differences in thermal performance between populations. In order to understand the molecular mechanisms that underlie adaptation to local thermal regimes in environmental vibrio populations, we employ genomic and transcriptomic approaches to examine transcriptomic changes that occur within strains grown at their thermal optima and under heat and cold stress. Moreover, we compare two closely-related strains with different laboratory thermal preferences to identify in situ evolutionary responses to different thermal environments in genome content and alleles as well as gene expression.

Using microarrays, we analyze the transcriptomes of the coral host, comparing the bleaching-resistant preconditioned treatment to non-preconditioned and control treatments. This experiment compared host gene expression of Acropora millepora across control, non-preconditioned, and preconditioned treatments. Fragments were sampled prior to preconditioning (Day 4), following 10 days of thermal preconditioning (Day 20), and after two (Day 23), four (Day 25), and eight days (Day 29) of 31M-BM-0C thermal challenge. The analysis implements 45 arrays, representing 5 sampling points of three treatments (n=3).

Project description:Several microorganisms have wide temperature growth range and versatility to tolerate large thermal fluctuations in diverse environments. To better understand thermal adaptation of psychrotrophs, Exiguobacterium sibiricum strain 255-15 was used, a psychrotrophic bacterium that grows from -5°C to 39°C. Its genome is approximately 3 Mb in size, has a GC content of 47.7% and includes 2,978 putative protein-encoding genes (CDS). The genome and transcriptome analysis along with the organism's known physiology was used to better understand its thermal adaptation. A total of about 27%, 3.2% and 5.2% of E. sibiricum strain 255-15 CDS spotted on the DNA microarray yielded differentially expressed genes in cells grown at -2.5°C, 10°C and 39°C, respectively, when compared to cells grown at 28°C. The hypothetical and unknown genes represented 10.6%, 0.89% and 2.3% of the CDS differentially expressed when grown at -2.5°C, 10°C and 39°C versus 28°C. The transcriptome analyses showed that E. sibiricum is constitutively adapted to cold temperatures since little differential gene expression was observed at growth temperatures of 10°C and 28°C, but at the extremities of its Arrhenius growth profile, namely -2.5°C and 39°C, much more differential gene expression occurred. The genes that responded were more typically associated with stress response. Keywords: stress response to cold and hot temperatures

Project description:Here we use a transcriptomic approach to investigate the molecular underpinnings of thermal acclimation in the model diatom species Phaeodactylum tricornutum by comparing the differential gene expression in cultures acclimated to sub-optimal, optimal, and supra-optimal temperatures (10, 20 and 26.5 °C, respectively).
