Schematic representation of the genome composition of Xcc strains based on aCGH analyses. The left-most line indicates the physical map scaled in megabases from the first base, the start of the putative replication origin. The curve indicates the GC content in the genome of strain 8004. The image of the hierarchical clustering was based on the aCGH results of 20 Xcc strains. The number of Xcc strains on the top shows that each column indicates each strain. Each tiny line indicates a specific CDS on the array, and the CDSs are arranged in the order of the genome of strain 8004. Each green line indicates an AHD CDS in the corresponding test strain. The serial numbers on the right indicate the variable genomic regions of Xcc.
