Figure 5

Frequency histograms of intron numbers in all 108 IRK genes examined. Figure A, B , and C represent the histograms for three major groups of vertebrate IRKs, that is, ATP-regulated, elementary, and G-protein-activated IRK groups, respectively. Anamniotic vertebrates mean fish and amphibians, and amniotic birds and mammals. Abscissa, Intron numbers. Ordinate, Number of genes, which showed numbers of intron insertions in the coding regions as indicated on the abscissa. Figure D is the similar histogram for IRK genes of protostomic clade, that is, Caenorhabditis elegans and brigssae, and Drosophila melanogaster and Anofeles gambiae.
