Intron gain and loss rates of eukaryotic lineages. (Blue) Lineages exhibiting the balanced mode of evolution; (red) lineages with elevated loss rate; (green) lineages with elevated gain rate. The brown Ascomycota indicates the only lineage with both the gain rate and loss rate elevated. (Inset) An expanded view of the low-rate area that was obtained by excluding three lineages: Deuterostomia, Ascomycota, and S. cerevisiae. Selected lineages are labeled. Species and lineage abbreviations are as in Fig. 1.
