Rarefaction curves for the core (a) and accessory (b) genome of P. syringae, as estimated using PanGP. a Families present in 95% (soft-core genome) and 100% (hard core genome) of P. syringae strains exponentially decays as each new genome is added to the analysis. b The total number of gene families identified continues to increase indefinitely as each new genome is added to the analysis when singleton gene families (families that are only present in one strain) are included, suggesting that P. syringae has an open pan-genome
