FIGURE 2.
The distribution of a minimal set of 131 serovar-specific genes in 106 serovars. The Y-axis shows serovar or lineage-specific gene markers and the X-axis shows serovars or lineages. The details were listed in Supplementary Table S4. Gray indicated zero genomes containing a gene (TN). Gene/Genome pairs along the diagonal represent genomes containing the serovar-specific gene markers that matches their serovar (TP). Red represents genes that are present in 100% of genomes for a given serovar or lineage. Where a gene is present in less than 100% of a serovar a gradient from light blue (low percentage) to dark blue (high percentage) is displayed. Blue pairs along the diagonal represent the presence of FN. Pairs that are blue or red outside of the diagonal represent pairs containing genes that do not match the predicted serovar of the genome (FP).
