Spindle architecture constrains karyotype evolution. [PDF]

Nat Cell Biol
Abstract The eukaryotic cell division machinery must rapidly and reproducibly duplicate and partition the cell’s chromosomes in a carefully coordinated process. However, chromosome numbers vary dramatically between genomes, even on short evolutionary timescales.

Karyotype diversity in the genus Nysius Dallas, 1852 (Hemiptera, Heteroptera, Lygaeidae) is much greater than you might think [PDF]

Comparative Cytogenetics, 2023
We studied the karyotype and chromosomal distribution of 18S rDNA clustered in nucleolar organizer regions (NORs) in Nysius graminicola (Kolenati, 1845), belonging to the subfamily Orsillinae (Lygaeidae).

A comparative karyological study of Helianthemum (Cistaceae): karyotype size, karyotype symmetry and evolution of chromosome number

Anales del Jardín Botánico de Madrid, 2023
In this study we assessed karyotype size and symmetry for a comprehensive taxonomic and geographic representation of Helianthemum and reconstructed chromosome number evolution in the genus.

Karyotype Evolution in Aeshna (Aeshnidae, Odonata) [PDF]

Hereditas, 2004
The haploid DNA content of Aeshna confusa (2n = 27, n = 13 + XO, male). A. bonariensis (2n = 26, n = 12 + neo-XY, male) and A. cornigera planaltica (2n = 16, n = 7 + neo-XY, male) has been determined (2.16 ± 0.16 pg, 1.81 ± 0.17 pg, and 2.08 ± 0.08 pg, respectively).

Comparative chromosome painting in hummingbirds (Trochilidae) [PDF]

Genetics and Molecular Biology, 2020
Hummingbirds (Trochilidae) are one of the most enigmatic avian groups, and also among the most diverse, with approximately 360 recognized species in 106 genera, of which 43 are monotypic.
