Figure 4. Percentage of total Vibrio cholerae open reading frames (ORFs) in biological roles compared with other γ-Proteobacteria.
These were V. cholerae, chromosome 1 (blue); V. cholerae, chromosome 2 (red); Escherichia coli (yellow); Haemophilus influenzae (pale blue). Significant partitioning (P < 0.01) of biological roles between V. cholerae chromosomes is indicated with an asterisk, as determined with a χ2 analysis. 1, Hypothetical contains both conserved hypothetical proteins and hypothetical proteins, and is at 1/10 scale compared with other roles.
