Temperature is one of the most important factors for bacterial development. Cold environments are widely distributed on earth and microorganisms should develop different cellular adaptations to cope with the stress derived from low temperatures. Pseudomonas extremaustralis is an Antarctic bacterium able to grow under low temperatures. In this work, we analyzed the whole transcriptome of early exponential cultures of P. extremaustralis at 8°C by RNA deep-sequencing technology along with analysis of mutant strains of relevant genes. Transcriptomic data were analyzed by using Rockhopper software to determine differential expressed genes (P
