Hierarchical clustering of accessory genome data among six Listeria monocytogenes strains. Hierarchical clustering of the binary presence/absence values of the accessory genome of the Listeria monocytogenes strains F6900, 10403S, Clip81459, EGD-e, HCC23 and 4bF2365. The accessory genome was generated using the Panseq Core/Accessory Genome Analysis module with fragmentation size of 500 bp and sequence identity cutoff value of 85%. The dendrogram was produced by the statistical package R, using the hclust function with binary distance and average linkage; black indicates presence of a locus and white the absence of a locus.
