From: Structure and dynamics of the pan-genome of Streptococcus pneumoniae and closely related species
The S. pneumoniae pan-genome according to the finite supragenome model. (a) Number of new genes as a function of the number of sequenced genomes. The predicted number of new genes drops sharply to zero when the number of genomes exceeds 50. (b) Number of core genes as a function of the number of sequenced genomes. The number of core genes converges to 1,647 for number of genomes n→∞.
