Figure 5

Intron size distribution as estimated by the Blast-based protocol. The distribution of size in each gene (genes acronyms are marked on the left size of the graph) is shown with a so-called "barcode graph", in which each small vertical bar represent the size value of a given intron and each dot on the top of the vertical bar represent further introns which have the same size. From the distribution of intron sizes one record (AY955840 and its equivalent from full genome collection NC_007935) was removed because its size value was too large (>50000 bp) to be easily drawn on the graph.
