Figure 1

Pan and core genome analysis of 28 Prevotella genomes. The number of shared genes is plotted (violet) as a function of the number of Prevotella genomes sequentially considered. The continuous curve represents the calculated core genome size, exponential curve fit model (y core = A core e Bcore.x+ C core ) was applied to the data. The best fit was obtained with r 2 = 0.949, Acore = 5490.32, Bcore = −1.05, and Ccore = 567.29. The extrapolated Prevotella core genome size is 567. The size of Prevotella pan-genome is plotted (orange) as a function of the number of Prevotella genomes sequentially considered. The continuous curve represents calculated pan-genome size, the power-law regression model (y pan = A pan x Bpan+ C pan ) was applied to the data. The best fit was obtained with r 2 = 0.999, Apan = 2389.18, Bpan = 0.7, and Cpan = 66.29. The extrapolated Prevotella pan-genome size is 24685. The vertical bars correspond to standard deviations after repeating random combinations of the genomes.
