^aRepresentative taxon at high abundance in each sample. ^bNumber of CDS is the number of protein-coding genes in the sequenced reference genome of each taxon. ^cSister taxon used for identification of core genome (see main text). ^dPercentage of core is the percentage of protein-coding genes in each taxon that are shared with the sister taxon. CDS, coding sequence.
