Reconstruction of proto-vertebrate, proto-cyclostome and proto-gnathostome genomes provides new insights into early vertebrate evolution

Early vertebrate genomes were shaped by multiple whole-genome duplication (WGD) events of debated timings. Here the authors’ reconstruction of ancestral genomes using the probabilistic macrosynteny model supports a WGD shared by all vertebrates and a gnathostome-specific WGD, and reveals evidence of...

Description
Summary:Early vertebrate genomes were shaped by multiple whole-genome duplication (WGD) events of debated timings. Here the authors’ reconstruction of ancestral genomes using the probabilistic macrosynteny model supports a WGD shared by all vertebrates and a gnathostome-specific WGD, and reveals evidence of a cyclostome-specific genome triplication.
