Chromosomal Mapping of Repetitive DNAs in the Grasshopper Abracris flavolineata Reveal Possible Ancestry of the B Chromosome and H3 Histone Spreading
(2013-06-27)
Supernumerary chromosomes (B chromosomes) occur in approximately 15% of eukaryote species. Although these chromosomes have been extensively studied, knowledge concerning their specific molecular composition is lacking in ...
Chromosomal organization of repetitive DNA sequences in Astyanax bockmanni (Teleostei, Characiformes): dispersive location, association and co-localization in the genome
(2013-09-06)
Repetitive DNA sequences constitute a great portion of the genome of eukaryotes and are considered key components to comprehend evolutionary mechanisms and karyotypic differentiation. Aiming to contribute to the knowledge ...

A simple method for estimating global DNA methylation using bisulfite PCR of repetitive DNA elements
(Oxford University Press, 2004-02-01)
We report a method for studying global DNA methylation based on using bisulfite treatment of DNA and simultaneous PCR of multiple DNA repetitive elements, such as Alu elements and long interspersed nucleotide elements ...

Evolutionary dynamics of heterochromatin in the genome of Dichotomius beetles based on chromosomal analysis
(Springer, 2011-03-01)
We comparatively analyzed six Dichotomius species (Coleoptera: Scarabainae) through cytogenetic methods and mitochondrial genes sequencing in the aim to identify patterns of chromosomal evolution and heterochromatin ...

Tracking the evolution of sex chromosome systems in Melanoplinae grasshoppers through chromosomal mapping of repetitive DNA sequences
(2013-08-13)
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 ...
