Abstract

Parrot genomes characteristically have a reduced chromosome number compared with other birds. Using high-quality chromosome-level assemblies of monk parakeet and several other parrot genomes, the evolutionary processes and patterns of chromosomal rearrangements among parrot lineages are depicted. A burst of one transposable element (CR1-psi) unique to parrots has been identified, which is thought to have directly or indirectly contributed to chromosomal rearrangements. Furthermore, the loss of two genes (ALC1 and PARP3), related to genome stability, serves as a likely explanation for the elevated rate of chromosomal rearrangements in parrots.
