Chromosome numbers in the Triatominae (Hemiptera-Reduviidae): a review
The chromosome numbers of 46 out of the 122 currently recognized species of Triatominae (Hemiptera, Reduviidae) are summarized. We present the number of autosomes, the sex mechanism and the first reference for each karyotype.

The Role of Satellite DNAs in Genome Architecture and Sex Chromosome Evolution in Crambidae Moths
Tandem repeats are important parts of eukaryotic genomes being crucial e.g., for centromere and telomere function and chromatin modulation. In Lepidoptera, knowledge of tandem repeats is very limited despite the growing number of sequenced genomes.

Cytogenetic quantification of KNL1‐labelled kinetochores in Ornithogalum kochii reveals a significant positive scaling relationship between chromosome size and kinetochore size, demonstrating that chromosome–kinetochore scaling operates even across moderate intra‐karyotype size variation.

Orcein staining of spermatocytes was used to study the meiotic behavior of holocentric chromosomes in three member of the genus Antiteuchus (commonly known as stink bugs). We describe and illustrate the karyotype of Antiteuchus mixtus, A. sepulcralis and

ABSTRACT Accurate identification of centromeres in telomere‐to‐telomere (T2T) genomes remains difficult due to the rapid evolution of centromeric repeats and their lack of conserved sequence features. In this study, we present EasyCen, a lightweight sequence‐based framework for centromere identification and repeat‐architecture profiling across various ...

Due to the X-shape formation at somatic metaphase, the arrangement of the sister chromatids is obvious in monocentric chromosomes. In contrast, the sister chromatids of holocentric chromosomes cannot be distinguished even at mitotic metaphase. To clarify

Spider Mites: Genetic Models to Inform Herbivore and Chelicerate Biology
Chelicerates include spiders, scorpions and ticks, and also spider mites that damage crops. Many of the features that make spider mites crop pests have facilitated their adoption as genetically tractable chelicerates. The expanding genetic toolkit developed using spider mites has potential to inform genetic studies in other chelicerates as well ...

A densely sampled phylogeny of Carex section Lupulinae (107 specimens) is presented, along with a new cryptic species from the southern United States. This species is locally abundant and genetically and morphologically distinct from other Lupulinae. An identification key is provided and phenological and ecological patterns are discussed.

Data from: The phylogenetic origins and evolutionary history of holocentric chromosomes
In eukaryotes, we can recognize two kinds of chromosomes, based on the location of the kinetochores. The majority of eukaryotes have monocentric chromosomes, in which kinetochoric activity is concentrated in a single locus.
