Figure 2.

(a) Coverage of 10-mer sequence space as a function of genome size in 433 fully sequenced microbial genomes. The legend for the color-coding of GC content appears on the right. Smaller genomes have lower GC content. Anaeromyxobacter dehalogenans is an outlier with unusually low coverage for its genome size and GC content (outside of the 99.9% predicted interval). (b) A histogram for the proportion of the 10-mer sequence space covered by each of the 433 fully sequenced microbial genomes.
