Microarray analysis of the benthic bacterium Shewanella piezotolerans WP3 at low temperature

摘要

Low temperature is one of the most critical environmental factors influencing the microbial diversity and functioning of deep-sea ecosystem. In the present study, the global gene expression patterns of the deep-sea bacterium Shewanella piezotolerans WP3 at different temperatures (4 degrees C and 25 degrees C) were evaluated through DNA microarray analysis. We identified 185 and 183 genes in WP3 whose expression is increased and decreased, respectively, at 4 degrees C compared to growth at 25 degrees C. The functions of enriched genes were associated with transcription and translation, out membrane, amino acid transport and flagellar system. These data provided a transcriptome resource for the investigation of cold adaptation mechanism of deep-sea bacteria. (C) 2017 Elsevier B.V. All rights reserved.
