a, PCoA ordination based on composition of gene orthologues reveals two distinct F. prausnitzii genomogroups. Ordination performed with Euclidean distances. b, The 20 COG categories showing differential abundance between core and accessory genome in F. prausnitzii. COG categories on the right are enriched in the accessory part of species pangenome (p < 0.05 in Wilcoxon test)
