RepeatOBserver: Tandem Repeat Visualisation and Putative Centromere Detection. [PDF]
ABSTRACT Tandem repeats play an important role in centromere structure, subtelomeric regions, DNA methylation, recombination and the regulation of gene activity. Analysis of their distribution in genomes offers a potential means for predicting putative centromere locations, which continues to be a challenge for genome annotation.

X-linked heterochromatin distribution in the holocentric chromosomes of the green apple aphid Aphis pomi [PDF]
Chromatin organization in the holocentric chromosomes of the green apple aphid Aphis pomi has been investigated at a cytological level after C-banding, NOR, Giemsa, fluorochrome staining and fluorescent in situ hybridization (FISH).

Cytogenetic characterization of telomeres in the holocentric chromosomes of the lepidopteran Mamestra brassicae [PDF]
Telomeres of the Mamestra brassica holocentric chromosomes were studied by Southern blotting, in-situ hybridization and Bal31 assay evidencing the presence of the telomeric (TTAGG)(n) repeat.

Unique territorial and compartmental organization of chromosomes in the holocentric silkmoth
Abstract The hallmarks of chromosome organization in multicellular eukaryotes are chromosome territories (CT), chromatin compartments, and insulated domains, including topologically associated domains (TADs). Yet, most of these elements of chromosome organization are derived from analyses of a limited set of model organisms, while large ...

Chromosome Segregation Is Biased by Kinetochore Size [PDF]
Chromosome missegregation during mitosis or meiosis is a hallmark of cancer and the main cause of prenatal death in humans. The gain or loss of specific chromosomes is thought to be random, with cell viability being essentially determined by selection ...

The Glanville fritillary genome retains an ancient karyotype and reveals selective chromosomal fusions in Lepidoptera [PDF]
Previous studies have reported that chromosome synteny in Lepidoptera has been well conserved, yet the number of haploid chromosomes varies widely from 5 to 223.

Karyotype rearrangements and telomere analysis in Myzus persicae (Hemiptera, Aphididae) strains collected on Lavandula sp. plants [PDF]
Karyotype analysis of nine strains of the peach-potato aphid Myzus persicae (Sulzer, 1776), collected on Lavandula sp. plants, evidenced showed that five of them had a standard 2n = 12 karyotype, one possessed a fragmentation of the X chromosome ...

Spermatogenesis and nucleolar activity in Triatoma klugi (triatomine, Heteroptera)
Triatoma klugi is a Chagas disease vector in the Rio Grande do Sul State. Triatominae chromosomes are holocentric and sex chromosomes segregation is post-reductional. In this paper we describe the karyotype of male T.

Distribution and molecular composition of heterochromatin in the holocentric chromosomes of the aphid Rhopalosiphum padi (Hemiptera: Aphididae) [PDF]
In order to study the structure of holocentric chromosomes in aphids, the localization and the composition of Rhopalosiphum padi heterochromatin and rDNA genes have been evaluated at cytogenetic and molecular level.

Cytogenetics as a tool for Triatomine species distinction (Hemiptera-Reduviidae)
Several cytogenetic traits were tested a species diagnostic characters on five triatomine species: Rhodnius pictipes, R. nasutus, R. robustus, Triatoma matogrossensis and T. pseudomaculata. Four of them are described for the first time.
