Transcription profiling of Photobacterium profundum SS9 strain cells grown at two different pressure conditions 45 MPa and at 28 MPa

ABSTRACT: P. profundum SS9 strain cells were grown at two different pressure conditions 45 MPa and at 28 MPa. RNA extracted from the two different cultures was labelled with Cy5 and Cy3 and competitively hybridized on the same slide.

BACKGROUND: Oceans cover approximately 70% of the Earth's surface with an average depth of 3800 m and a pressure of 38 MPa, thus a large part of the biosphere is occupied by high pressure environments. Piezophilic (pressure-loving) organisms are adapted to deep-sea life and grow optimally at pressures higher than 0.1 MPa. To better understand high pressure adaptation from a genomic point of view three different Photobacterium profundum strains were compared. Using the sequenced piezophile P. pro  ...[more]
