Figure 1

Conservation of intron positions between eukaryotic species. The scale to the right shows the pairwise conservation level of intron positions, measured as the log-ratio of the observed number of shared positions to the number expected by chance (see text). The expected value of this ratio is 0, so the positive values indicate an excess of shared intron positions, and the negative values indicate an unexpected deficit of such positions. Species and lineage abbreviations: Anoga (Anopheles gambiae), Arath (Arabidopsis thaliana), Aspfu (Aspergillus fumigatus), Caeel (Caenorhabditis elegans), Cioin (Ciona intestinalis), Cryne (Cryptococcus neoformans), Danre (Danio rerio), Dicdi (Dictyostelium discoideum), Drome (Drosophila melanogaster), Galga (Gallus gallus), Homsa (Homo sapiens), Neucr (Neurospora crassa), Orysa (Oryza sativa), Plafa (Plasmodium falciparum), Sacce (Saccharomyces cerevisiae), Schpo (Schizosaccharomyces pombe), Strpu (Strongylocentrotus purpuratus), Thepa (Theileria parva), roden (Mus musculus and Rattus norvegicus combined).
