Genomic IS copy number. Genomic copy numbers of four families as they were found on chromosomes and plasmids. Families IS4, IS1634, ISH3 and IS701 are represented in red, blue, green and purple, respectively. The number of copies located on chromosomes is represented by cylinders while those located on plasmids is shown as cones. The height of each cylinder/cone indicates the number of chromosome/plasmid displaying the corresponding number of IS family members. No distinction was made when different elements of the same IS family occurred in the same genome. The histograms include intact elements, disrupted full length copies and large partial fragments displaying more than 95 % DNA sequence identity. Genomes without any copy of the aforementioned families were not included.
