Chromosome painting: a useful art [PDF]

Human Molecular Genetics, 1998
Chromosome 'painting' refers to the hybridization of fluorescently labeled chromosome-specific, composite probe pools to cytological preparations. Chromosome painting allows the visualization of individual chromosomes in metaphase or interphase cells and the identification of both numerical and structural chromosomal aberrations in human pathology with

Delimiting the origin of a B chromosome by FISH mapping, chromosome painting and DNA sequence analysis in Astyanax paranae (Teleostei, Characiformes). [PDF]

PLoS ONE, 2014
Supernumerary (B) chromosomes have been shown to contain a wide variety of repetitive sequences. For this reason, fluorescent in situ hybridisation (FISH) is a useful tool for ascertaining the origin of these genomic elements, especially when combined ...

Rapid Karyotype Evolution in Lasiopodomys Involved at Least Two Autosome - Sex Chromosome Translocations. [PDF]

PLoS ONE, 2016
The generic status of Lasiopodomys and its division into subgenera Lasiopodomys (L. mandarinus, L. brandtii) and Stenocranius (L. gregalis, L. raddei) are not generally accepted because of contradictions between the morphological and molecular data.

Single origin of sex chromosomes and multiple origins of B chromosomes in fish genus Characidium. [PDF]

PLoS ONE, 2014
Chromosome painting with DNA probes obtained from supernumerary (B) and sex chromosomes in three species of fish genus Characidium (C. gomesi, C. pterostictum and C.

Cytotaxonomy of Gallinula melanops (Gruiformes, Rallidae): Karyotype evolution and phylogenetic inference [PDF]

Genetics and Molecular Biology, 2021
Although Rallidae is the most diverse family within Gruiformes, there is little information concerning the karyotype of the species in this group. In fact, Gallinula melanops, a species of Rallidae found in Brazil, is among the few species studied ...

Fast-Painting of Human Metaphase Spreads Using a Chromosome-Specific, Repeat-Depleted DNA Library Probe

BioTechniques, 1998
For chromosome painting, in situ suppression of repetitive DNA sequences has been well established. Such standard protocols usually require large amounts of Cot-1 DNA®.

Chromosomal painting in Charadrius collaris Vieillot, 1818 and Vanellus chilensis Molina, 1782 and an analysis of chromosomal signatures in Charadriiformes.

PLoS ONE, 2022
Charadriiformes represent one of the largest orders of birds; members of this order are diverse in morphology, behavior and reproduction, making them an excellent model for studying evolution.

Chromosomal painting of the sandpiper (Actitis macularius) detects several fissions for the Scolopacidae family (Charadriiformes)

BMC Ecology and Evolution, 2021
Background The Scolopacidae family (Suborder Scolopaci, Charadriiformes) is composed of sandpipers and snipes; these birds are long-distance migrants that show great diversity in their behavior and habitat use.
