Pan-genome analysis from twenty-two isolates of F. oreochromis, F. covae, and F. davisii. A The number of core genes, accessory genes, and unique genes presented in each isolate. B COG functional categories of core genes, accessory genes, and unique genes among twenty-two isolates. C Core pan-genome curves of power-fit and exponential are indicated by brown lines, and purple lines. The corresponded equations are provided within the figure legend. The blue dots indicated total gene families; the pink dots indicated core gene families. D Phylogenetic analysis based on the core gene sequence of twenty-two isolates of F. oreochromis, F. covae, and F. davisii.
