DOI: 10.1038/s41467-025-59640-2
Abstract: The ancestral crucifer karyotype and 22 conserved genomic blocks (CGBs) facilitate phylogenomic analyses in the Brassicaceae. Chromosomal rearrangements reshuffled CGBs of ancestral chromosomes during karyotype evolution. Here, we identify eight protochromosomes representing the common ancestral… read more here.

DOI: 10.1038/s42003-020-1096-9
Abstract: Closely related muntjac deer show striking karyotype differences. Here we describe chromosome-scale genome assemblies for Chinese and Indian muntjacs, Muntiacus reevesi (2 n = 46) and Muntiacus muntjak vaginalis (2 n = 6/7), and analyze their evolution… read more here.

DOI: 10.1063/5.0206011
Abstract: In the evolution of species, the karyotype changes with a timescale of tens to hundreds of thousand years. In the development of cancer, the karyotype often is modified in cancerous cells over the lifetime of… read more here.

DOI: 10.1093/molbev/msac221
Abstract: Karyotype refers to the configuration of the genome into a set of chromosomes. The karyotype difference between species is expected to impede various biological processes, such as chromosome segregation or meiotic chromosome pairing, potentially contributing… read more here.

Divide to Conquer: Evolutionary History of Allioideae Tribes (Amaryllidaceae) Is Linked to Distinct Trends of Karyotype Evolution
Sign Up to like & getrecommendations! Published in 2020 at "Frontiers in Plant Science"
DOI: 10.3389/fpls.2020.00320
Abstract: Allioideae (e.g., chives, garlics, onions) comprises three mainly temperate tribes: Allieae (800 species from the northern hemisphere), Gilliesieae (80 South American species), and Tulbaghieae (26 Southern African species). We reconstructed the phylogeny of Allioideae (190… read more here.

Oligo-barcode illuminates holocentric karyotype evolution in Rhynchospora (Cyperaceae)

DOI: 10.3389/fpls.2024.1330927
Abstract: Holocentric karyotypes are assumed to rapidly evolve through chromosome fusions and fissions due to the diffuse nature of their centromeres. Here, we took advantage of the recent availability of a chromosome-scale reference genome for Rhynchospora… read more here.
