Core and pan genomes of O. oeni . A. Proportions of core (conserved) ORFs, strain-specific ORFs and putative pseudogenes in fourteen strains of O. oeni. The overall number of each type of ORF is also indicated based upon syntenic assignment of orthologs across all fourteen strains. B. The estimated average size of the O. oeni core (pink solid line) and pan (light blue solid line) genomes as a function of the number of individual strains compared. For each point, the size of core and pan genome was calculated for all combinations of x strains from the fourteen strains analysed with the results presented as filled circles.
