Gene presence–absence of 38 V . aestuarianus . Presence–absence heatmap of the pangenome of 38 V . aestuarianus genomes generated by Phandango [26]. Dark blue blocks indicate the presence of a gene family. The proportion of genomes each gene family has been detected in is shown below the heatmap. Tree branches and heatmap rows are coloured by country of isolation. Tree lengths have been truncated, see Fig. 2 for true branch lengths. Indicated in a red box are multiple genes that differ between clade A and clade B. Isolates 01151 and 01032, French clade B isolates, notably contain most of these genes.
