Biologists Sequence Iberian Ribbed Newt Genome at High Resolution

Aquatic, tailed amphibians called newts have large genomes harboring many repeat elements. How these elements shape the genome and relate to newts’ unique regeneration ability remains unknown. In new research, scientists from Karolinska Institute and elsewhere produced a chromosome-scale genomic sequence for the Iberian ribbed newt (Pleurodeles waltl).

Brown et al. present the chromosome-scale assembly of the 20.3 Gb genome of the Iberian ribbed newt (Pleurodeles waltl), with a unprecedented contiguity and completeness among giant genomes. Image credit: Brown et al., doi: 10.1016/j.xgen.2025.100761.
