Dnmt1 mediates epigenetic restriction of invasive traits in clonal crayfish.

Nature communications - 26 Mar 2026

Diaz-Larrosa J Jaime, Carneiro Vitor, Hanna Katharina, Raddatz Günter, Lyko Frank

Abstract excerpt

Procambarus virginalis (marbled crayfish) is a parthenogenetically reproducing invasive crayfish species. Its global population is monoclonal, which raises questions about the mechanisms promoting their invasiveness. Here we show that environmental changes downregulate the highly conserved Dnmt1 DNA methyltransferase in marbled crayfish. When phenocopying this effect through a dsRNA-based in vivo knockdown, we...
