Comparative cytogenetics of Auchenorrhyncha (Hemiptera, Homoptera): a review. [PDF]
Zookeys, 2015 A comprehensive review of cytogenetic features is provided for the large hemipteran suborder Auche norrhyncha, which currently contains approximately 42,000 valid species. This review is based on the analysis of 819 species, 483 genera, and 31 families

Behaviour of ring bivalents in holokinetic systems : Alternative sites of spindle attachment in Pachylis argentinus and Nezara viridula (Heteroptera) [PDF]
Chromosome Research, 2003 Heteropteran chromosomes are holokinetic; during mitosis, sister chromatids segregate parallel to each other but, during meiosis, kinetic activity is restricted to one pair of telomeric regions.

Detection of telomeric sequences and ribosomal RNA genes in holokinetic chromosomes of five jumping plant-lice species: First data on the superfamily Psylloidea (Hemiptera: Sternorrhyncha) [PDF]
European Journal of Entomology, 2018 Fluorescence in situ hybridization (FISH) is a technique used to determine the chromosomal position of DNA and RNA probes. The present study contributes to knowledge on jumping plant-lice genomes by using FISH with 18S rDNA and telomeric (TTAGG)n probes ...

Absence of positive selection on CenH3 in Luzula suggests that holokinetic chromosomes may suppress centromere drive. [PDF]
Ann Bot, 2016 The centromere drive theory explains diversity of eukaryotic centromeres as a consequence of the recurrent conflict between centromeric repeats and centromeric histone H3 (CenH3), in which selfish centromeres exploit meiotic asymmetry and CenH3 evolves adaptively to counterbalance deleterious consequences of driving centromeres. Accordingly, adaptively

Molecular Ecology, Volume 32, Issue 21, Page 5785-5797, November 2023., 2023 Abstract Using recently published chromosome‐length genome assemblies of two damselfly species, Ischnura elegans and Platycnemis pennipes, and two dragonfly species, Pantala flavescens and Tanypteryx hageni, we demonstrate that the autosomes of Odonata have undergone few fission, fusion, or inversion events, despite 250 million years of separation.

The Plant Journal, Volume 116, Issue 2, Page 446-466, October 2023., 2023 SUMMARY Although the South African Cape flora is one of the most remarkable biodiversity hotspots, its high diversity has not been associated with polyploidy. Here, we report the chromosome‐scale genome assembly of an ephemeral cruciferous species Heliophila variabilis (~334 Mb, n = 11) adapted to South African semiarid biomes. Two pairs of differently

Insect Molecular Biology, Volume 30, Issue 2, Page 188-209, April 2021., 2021 The annotated genome of predatory mirid Nesidiocoris tenuis presented here was generated from a single female insect using a linked‐read sequencing and assembly strategy. Potential contaminants and/or endosymbionts were identified during assembly decontamination along with putative lateral gene transfer candidates.

N-banding pattern of holokinetic chromosomes and its relation to chromosome structure [PDF]
Hereditas, 2008 Nokkala, S. and Nokkala, C. 1984. N-banding pattern of holokinetic chromosomes and its relation to chromosome structure. —-Hereditas 100: 61–65. Lund, Sweden. ISSN 0018–0661. Received April 20, 1983 A new method for N-banding is described, by which the N-banding pattern of holokinetic chromosomes in mitosis and meiosis was studied.
