| contents | Breaking bad: when clitellate genomes go rogue. Vargas-Chávez, Carlos McLysaght, Aoife Fernández, Rosa Genome Animals Gene Rearrangement Evolution, Molecular Annelida Clitellate genomes are the result of a profound genome reshaping compared to marine annelids, as if their genomes had exploded into thousands of atomic pieces and were reassembled in a different order by evolution. Recent studies not only revealed widespread gene order shuffling and massive rearrangements but also point to a potential adaptive rationale for this architectural chaos. What triggered such extreme rearrangements, and what molecular logic (if any) underlies their persistence? What is the role of spatial organization and regulatory rewiring in the maintenance of functional integrity in how the genome adjusts to this newly disordered architecture? By synthesizing current discoveries, this review outlines the mechanisms, consequences, and evolutionary paradoxes of genome rearrangement in clitellates, highlighting them as models of extreme yet functional genome plasticity. |
