From: Analysis of the Pantoea ananatis pan-genome reveals factors underlying its ability to colonize and interact with plant, insect and vertebrate hosts

Figure 2

Plots of the core CDSs, strain-specific CDSs and pan-genome CDSs of the species P. ananatis . Comparisons of n = 1→8 genomes were performed to determine the core genome CDSs for the eight sequenced P. ananatis strains (A), the strain-unique CDSs (TCs) added by each genome in the comparison (B), and the P. ananatis pan-genome size (expressed as number of CDSs) (C). Black circles indicate the data points. The data were fitted to a generalized least-squares non-linear model as per [12] to determine the core CDSs (A) and strain-unique CDSs (B) for the species when more sequenced strains are added to the comparison, as depicted by the triangles and trend line (blue for core CDSs and red for strain-unique CDSs) in the plots, while the dashed line shows the asymptotic core (A) and strain-specific CDSs (B) values for the species as predicted using the least-squares non-linear model function. The pan-genome for the species was extrapolated by fitting the strain-specific CDS data and average number of CDSs per compared genome to an algebraic function as per [12], indicated by green triangles (C).
