Transcriptome analysis of Shewanella oneidensis MR-1 in response to cold shock

(Submitter supplied) This study presents a global transcriptional analysis of the cold shock response of Shewanella oneidensis MR-1 after a temperature downshift from 30 to 8 or 15oC based on time-series microarray experiments. More than 700 genes were found to be significantly affected (p < 0.05) upon cold shock challenge, especially at 8oC. The temporal gene expression patterns of the classical cold-shock genes varied and only some of them, most notably so1648 and so2787, were differentially regulated in response to temperature downshift. more...

Changes in Shewanella baltica transcriptome upon cold stress

(Submitter supplied) In this work we analyzed changes in gene espression in Shewanella baltica upon cold stress. In order to imitate natural environment, we cultured bacteria in the Instant Ocean medium in a chemostat. Samples were collected after 90 and 180 minutes of cold stress and analyzed by RNA sequencing. The transcriptomic response could be characterized as global downregulation of gene expression (613 genes downregulated) and we found only 242 genes which were upregulated. more...

Effects of High Hydrostatic Pressure on Expression Profiles of In Vitro Produced Vitrified Bovine Blastocysts

(Submitter supplied) High hydrostatic pressure (HHP) has been used to pre-condition embryos before essential, yet potentially detrimental procedures such as cryopreservation. However, the mechanisms for HHP are poorly understood. We treated bovine blastocysts with three different HHP (40, 60 and 80 MPa) in combination with three recovery periods (0, 1h, 2h post HHP). Re-expansion rates were significantly higher at 40 and 60 but lower at 80 MPa after vitrification-warming in the treated groups than controls. more...

Several genes expression patterns in Desulfovibrio hydrothermalis sp. nov. AM13T in response to hydrostatic pressure

(Submitter supplied) We have identified differentially expressed genes according to hydrostatic pressure growth conditions in Desulfovibrio hydrothermalis. The transcriptomic datasets report the molecular mechanisms which could be involved in such adaptation and give information for the piezophile sulfate-reducing bacteria research communities. The data obtained pointed out a gradual response of D. hydrothermalis to an increase of hydrostatic pressure, with a threshold above 10 MPa and the involvement of a quite limited number of genes and/or pathways involved in the adaptation to hydrostatic pressure.

Microarray transcriptional profiling of Arctic Mesorhizobium strain N33 at low temperature provides insights into cold adaption strategies

(Submitter supplied) Arctic Mesorhizobium strain N33 was isolated from nodules of the Oxytropis arctobia in Canada’s eastern Arctic. This symbiotic bacterium can grow from 0 to 30°C, is one of the best known cold-adapted rhizobia, and can fix nitrogen at ~10°C. Here, the key molecular mechanisms of cold adaptation were investigated by determining changes in transcript profiles when cells were treated under eight different temperature conditions, including both sustained and transient cold treatments compared with cells grown at room temperature.

Transcriptome analysis of B. subtilis cells during recovery from injury after high hydrostatic pressure treatment

(Submitter supplied) Vegetative cells of B. subtilis can recover from injury caused by high hydrostatic pressure (HHP) treatment at 250 MPa. DNA microarray analysis revealed that many ribosomal genes and translation relating factors (e.g. translation initiation factors) were induced during a growth-arrested phase after the HHP treatment. Expression of cold shock-responsive genes, whose products play key roles for efficient translation, and heat shock-responsive genes, whose product mediates the correct protein folding or degrades misfolded proteins, were also induced. more...

Global Transcriptome Analysis of Tropheryma whipplei in Response to Temperature Stresses

(Submitter supplied) Microarray analysis of the global gene expression patterns of Tropheryma whipplei in response to thermal stresses showed unique transcription profiles. A few genes were regulated after 15 min exposure at 43°C, including the dnaK regulon composed of grpE, hspR, dnaK, clpB, cbpA as well as the TWT745 ORFan gene which might encode for another heat-shock protein. This operon is likely to be regulated by two HspR associated inverted repeats (HAIR motifs) found within its 5' region. more...

Sex dependent transcriptomic and reproductive response of the diamondback moth (Plutella xylostella) to cold stress

(Submitter supplied) Temperature has fundamental influences on fitness and distribution of insects. There have been very few studies on effects of mild cold conditions on insects. We found Plutella xylostella had reduced fitness and females produced few viable eggs when reared at 10°C, a temperature at which they can complete development. Male moths reared at 10°C were not able to fertilize eggs, but the eggs produced by female moths reared at this temperature were viable and could be fertilisied by males moths reared at a warmer temperature (25°C). more...
