Relationship between gene sequence length (i.e., size) and number of transposon insertions for the two chromosomes and three plasmids in the V. anguillarum NB10Sm genome. There was significant correlation between gene sequence length and number of transposon insertions for the chromosomes and 67-kb plasmid and the R² values were 0.61, 0.70, 0.60, 0.58, and 0.25 for Chromosome I, Chromosome II, Plasmid 67k, Plasmid 8k and Plasmid 6k, respectively. Slopes were calculated by regression where possible: 0.011, 0.012, and 0.029 for Chromosome I, Chromosome II, and 67-kb plasmid, respectively.
