Descending Dysploidy and Bidirectional Changes in Genome Size Accompanied Crepis (Asteraceae) Evolution. [PDF]
Genes (Basel), 2021 The evolution of the karyotype and genome size was examined in species of Crepis sensu lato. The phylogenetic relationships, inferred from the plastid and nrITS DNA sequences, were used as a framework to infer the patterns of karyotype evolution.

“End-to-End Chromosome Fusion” as the Main Driver of Descending Dysploidy in Vigna lasiocarpa (Mart. ex Benth.) Verdc. (Leguminosae Juss.) [PDF]
PlantsThe genus Vigna Savi (Leguminosae Juss.) comprises approximately 150 species, classified into five subgenera, most of which exhibit a diploid chromosome number of 2n = 22. However, the wild species Vigna lasiocarpa (Benth) Verdc. (V. subg. Lasiospron) is

Centromere diversity and its evolutionary impacts on plant karyotypes and plant reproduction. [PDF]
New PhytolSummary Karyotype changes are a formidable evolutionary force by directly impacting cross‐incompatibility, gene dosage, genetic linkage, chromosome segregation, and meiotic recombination landscape. These changes often arise spontaneously and are commonly detected within plant lineages, even between closely related accessions.

Karyotypic changes through dysploidy persist longer over evolutionary time than polyploid changes. [PDF]
PLoS ONE, 2014 Chromosome evolution has been demonstrated to have profound effects on diversification rates and speciation in angiosperms. While polyploidy has predated some major radiations in plants, it has also been related to decreased diversification rates.

The Genome Sequence of Gossypioides kirkii Illustrates a Descending Dysploidy in Plants [PDF]
Frontiers in Plant Science, 2019 One of the extraordinary aspects of plant genome evolution is variation in chromosome number, particularly that among closely related species. This is exemplified by the cotton genus (Gossypium) and its relatives, where most species and genera have a ...

The Evolution of Cytogenetic Traits in Cuscuta (Convolvulaceae), the Genus With the Most Diverse Chromosomes in Angiosperms [PDF]
Frontiers in Plant Science, 2022 Karyotypes are characterized by traits such as chromosome number, which can change through whole-genome duplication and dysploidy. In the parasitic plant genus Cuscuta (Convolvulaceae), chromosome numbers vary more than 18-fold.
