Amino acid composition and G+C content comparison between cold- and warm-adapted γ-proteobacteria.

Note: Cold adapted marine γ-proteobacteria included five cold-adapted Shewanella (dark blue triangles, Fig 2) and two strains of Pseudoalteromonas,one strain of Colwellia, Photobacterium or Psychromonas indicated (dark blue circles, Fig. 2). Warm-adapted marine γ-proteobacteria included the rest 12 strains of Shewanella, 2 strains of Aeromonas and 7 strains of Vibrio (Light blue colour, Fig 2). Note: Δ (cold-warm), difference between cold and warm adapted; cold, cold adapted bacteria; warm, warm-adapted bacteria; §, amino acid composition was predicted by G+C correlation shown in Fig 6a2; nc, no correlation with GC;+, positive value; –, negative value; v, vary; p, p-value.
