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