Core genome and pan genome of the P. freudenreichii species. The core genome (a) and the pan genome (b) are represented as a variation of the gene pools after sequential addition of 20 P. freudenreichii genomes. The summary of ortholog group distribution between the strains is presented in a pie chart (c). Core genes- present in all of the strains; Soft core genes- present in 19 of the strains; Shell genes- present in 3-18 of the strains; Cloud genes- present in one or two strains only
