The paper analyzes genomic data from Entamoeba species to show coevolution of introns and splicing machinery, transformation of splicing signals, and widespread intron gain.

The paper identifies conserved spliceosomal proteins in fungi and humans that regulate splicing efficiency and suppress weak splice sites, suggesting a role in enabling intron diversity through error limitation.

The paper studies intron evolution in dinoflagellates, revealing a high diversity of intron-creating transposable elements and complex spliceosomal system transformations.
