Fig 2. Sequence space coverage (SSC) largely depends on genome length and GC-content.

Fig 2

(A) SSC for each genome is plotted for k ranging from 7 to 19 (odd). SSC exhibits a sigmoidal relationship with log-transformed genome length. (B) SSC of prokaryotic genomes, for k = 11 (gold color in panel A) is plotted with points colored by GC-content. GC-content has a moderately strong positive correlation with log-transformed genome length (change from blue to magenta color; Pearson correlation coefficient r = 0.606, p < 0.001). SSC decreases as GC-content differs from the random, 0.5 (bright green).
