(Submitter supplied) We have identified differentially expressed genes according to hydrostatic pressure growth conditions in Desulfovibrio piezophilus. 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 different responses of D. piezophilus to an increase of 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.

(Submitter supplied) Pyrococcus yayanosii CH1 is the first and only obligate piezophilic hyperthermophilic microorganism discovered so far, that extends the physical and chemical limits of life on Earth and strengthens the idea of the existence of a hyperthermophilic biosphere in the depth of our planet. It was isolated from the Ashadze hydrothermal vent at 4,100 m depth. Multi-omics analyses where performed in order to study the mechanisms implemented by the cell to face high hydrostatic pressure variations. more...

(Submitter supplied) Pseudothermotoga elfii strain DSM9442 and P. elfii subsp. lettingae strain TMOT are hyperthermophilic bacteria. P. elfii is a moderate piezophile, isolated from an oil-producing well in Africa at a depth of more than 1600 m. P. lettingae is piezotolerant, isolated from a thermophilic bioreactor fed with methanol as the sole carbon and energy source. In this study, we analysed these bacteria at the genomic and transcriptomic levels. more...

(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.
