Chromosomal copy number variation reveals differential levels of genomic plasticity in distinct Trypanosoma cruzi strains
(BioMed Central, 2015)
Background: Trypanosoma cruzi, the etiologic agent of Chagas disease, is currently divided into six discrete typing units (DTUs), named TcI-TcVI. CL Brener, the reference strain of the T. cruzi genome project, is a hybrid ...
Using telomeric chromosomal aberrations to evaluate clastogen-induced genomic instability in mammalian cells
(Springer, 2020-12)
Telomeres, the specialized nucleoproteic complexes localized at the physical ends of linear eukaryotic chromosomes, play a fundamental role in maintaining chromosomal stability and integrity, being one of the leading ...
Structural chromosome instability: Types, origins, consequences, and therapeutic opportunities
(Molecular Diversity Preservation International, 2021-06)
Chromosomal instability (CIN) refers to an increased rate of acquisition of numerical and structural changes in chromosomes and is considered an enabling characteristic of tumors. Given its role as a facilitator of genomic ...

Tracking the evolution of sex chromosome systems in Melanoplinae grasshoppers through chromosomal mapping of repetitive DNA sequences
(BioMed Central, 2013-08)
Background: The accumulation of repetitive DNA during sex chromosome differentiation is a common feature of many eukaryotes and becomes more evident after recombination has been restricted or abolished. The accumulated ...
Chromosome evolution and phylogeny in Ronderosia (Orthoptera, Acrididae, Melanoplinae): clues of survivors to the challenge of sympatry?
(Wiley Blackwell Publishing, Inc, 2019-01)
In an attempt to unveil the origin of neo-sex chromosomes in Ronderosia Cigliano grasshoppers, we performed a combined phylogenetic analysis based on morphological (external morphology and male genitalia) and molecular ...
Data reassessment in a phylogenetic context gives insight into chromosome evolution in the giant genus Solanum (Solanaceae)
(Cambridge University Press, 2018-05)
Chromosome data are fundamental in evolution. However, there has been no attempt to synthesize and evaluate the significance of such information from a phylogenetic perspective in the giant genus Solanum, which was the aim ...
A Peruvian Child with 18p-/18q+ Syndrome and Persistent Microscopic Hematuria
(Thieme Gruppe, 2016)
Chromosome 18 pericentric inversion carriers could have offspring with recombinant chromosomes, leading to patients with clinical variable manifestations. Patients with 18p-/18q+ rearrangements share some clinical ...
IAPT chromosome data 28
(International Association for Plant Taxonomy, 2018-12)
The chromosome numbers of 28 and karyotype features of 17 taxa of Cactaceae are presented.Physical mapping by FISH for four species (Arrojadoa rhodacantha, Melocactus bahiensis, Pachycereus pringlei, Tacinga inamoena)were ...
Sex Chromosome Turnover in Moths of the Diverse Superfamily Gelechioidea
(Oxford University Press, 2019-04-08)
Sex chromosomes play a central role in genetics of speciation and their turnover was suggested to promote divergence. Invertebrates, sex chromosome–autosome fusions resulting in neo-sex chromosomes occur frequently in male ...
