Tempo and mode in karyotype evolution revealed by a probabilistic model incorporating both chromosome number and morphology. [PDF]

open access: yesPLoS Genetics, 2021
Karyotype, including the chromosome and arm numbers, is a fundamental genetic characteristic of all organisms and has long been used as a species-diagnostic character.

A high-quality Buxus austro-yunnanensis (Buxales) genome provides new insights into karyotype evolution in early eudicots [PDF]

open access: yesBMC Biology, 2022
Background Eudicots are the most diverse group of flowering plants that compromise five well-defined lineages: core eudicots, Ranunculales, Proteales, Trochodendrales, and Buxales.

Mechanisms of Rapid Karyotype Evolution in Mammals. [PDF]

open access: yesGenes (Basel), 2023
Chromosome reshuffling events are often a foundational mechanism by which speciation can occur, giving rise to highly derivative karyotypes even amongst closely related species.

Convergent Patterns of Karyotype Evolution Underlying Karyotype Uniformity in Conifers. [PDF]

open access: yesAdv Sci (Weinh)
Karyotype diversity plays an important role in speciation and diversification. However, gymnosperms, particularly conifers, exhibit remarkable karyotype uniformity.

Karyotype evolution in Fusarium. [PDF]

open access: yesIMA Fungus, 2018
The germ tube burst method (GTBM) was employed to examine karyotypes of 33 Fusarium species representative of 11 species complexes that span the phylogenetic breadth of the genus.

Dynamic turnover of centromeres drives karyotype evolution in Drosophila [PDF]

open access: yeseLife, 2019
Centromeres are the basic unit for chromosome inheritance, but their evolutionary dynamics is poorly understood. We generate high-quality reference genomes for multiple Drosophila obscura group species to reconstruct karyotype evolution.

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

open access: yesFrontiers in Plant Science
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 ...

Detecting Mechanisms of Karyotype Evolution in Heterotaxis (Orchidaceae). [PDF]

open access: yesPLoS ONE, 2016
The karyotype is shaped by different chromosome rearrangements during species evolution. However, determining which rearrangements are responsible for karyotype changes is a challenging task and the combination of a robust phylogeny with refined ...

Interspecies Chromosome Mapping in Caprimulgiformes, Piciformes, Suliformes, and Trogoniformes (Aves): Cytogenomic Insight into Microchromosome Organization and Karyotype Evolution in Birds. [PDF]

open access: yesCells, 2021
Interchromosomal rearrangements involving microchromosomes are rare events in birds. To date, they have been found mostly in Psittaciformes, Falconiformes, and Cuculiformes, although only a few orders have been analyzed.

Chromosome fusions shaped karyotype evolution and evolutionary relationships in the model family Brassicaceae. [PDF]

open access: yesNat Commun
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.
