The increased capacity of DNA sequencing has significantly advanced our understanding of
the phylogeny of birds and the proximate and ultimate mechanisms molding their genomic …

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 …

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 …

It is a broadly observed pattern that the non-recombining regions of sex-limited
chromosomes (Y and W) accumulate more repeats than the rest of the genome, even in …

The Y chromosome usually plays a critical role in determining male sex and comprises
sequence classes that have experienced unique evolutionary trajectories. Here 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 …

Background False duplications in genome assemblies lead to false biological conclusions.
We quantified false duplications in popularly used previous genome assemblies for …

Abstract The Qinghai-Tibet Plateau (QTP), possesses a climate as cold as that of the Arctic,
and also presents uniquely low oxygen concentrations and intense ultraviolet (UV) radiation …

In birds, sex is genetically determined; however, the molecular mechanism is not well-
understood. The avian Z sex chromosome (chrZ) lacks whole chromosome inactivation, in …
