Microchromosomes are prevalent in nonmammalian vertebrates [PD Waters et al., Proc.
Natl. Acad. Sci. USA 118 (2021)], but a few of them are missing in bird genome assemblies …

With more than 70,000 living species, vertebrates have a huge impact on the field of biology
and research, including karyotype evolution. One prominent aspect of many vertebrate …

The chicken continues to hold its position as a leading model organism within many areas of
research, as well as being a major source of protein for human consumption. The First …

Microchromosomes, once considered unimportant shreds of the chicken genome, are gene-
rich elements with a high GC content and few transposable elements. Their origin has been …

Sturgeons and paddlefishes (Acipenseriformes) occupy the basal position of ray-finned
fishes, although they have cartilaginous skeletons as in Chondrichthyes. This evolutionary …

A set of high-quality pan-genomes would help identify important genes that are still
hidden/incomplete in bird reference genomes. In an attempt to address these issues, we …

The karyotype of most birds has remained considerably stable during more than 100 million
years' evolution, except for some groups, such as parrots. The evolutionary processes and …

The slow-evolving invertebrate amphioxus has an irreplaceable role in advancing our
understanding of the vertebrate origin and innovations. Here we resolve the nearly complete …

Emu and other ratites are more informative than any other birds in reconstructing the
evolution of the ancestral avian or vertebrate karyotype because of their much slower rate of …

In 2011, the first high-quality genome assembly of a squamate reptile (lizard or snake) was
published for the green anole. Dozens of genome assemblies were subsequently published …
