Overview of core and pan genome structure for the Francisella genus. A. Accumulation curve (core genome) for the number of genes in common as a function of the number of genomes analysed for the Francisella genus. B. Accumulation curve for the total number of genes (pan genome) as a function of the number of genomes analysed for clade 1 (F. tularensis, W. persica and F. hispaniensis)(red) and clade 2 (F. philomiragia and F. noatunensis)(yellow). C. Cumulative accumulation of total number genes when genomes are added according to the structure in the SNP phylogeny. Ftt – F. tularensis subsp. tularensis, Fth – F. tularensis subsp. holarctica, Ftm – F. tularensis subsp. mediasiatica, Fn – F. novicida, Fh – F. hispaniensis, W – Wolbachia persica, Fno – F. noatunensis subsp. orientalis, Fnn – F. noatunensis subsp. noatunensis, Fp – F. Philomiragia.
