The Ancestral Carnivore Karyotype As Substantiated by Comparative Chromosome Painting of Three Pinnipeds, the Walrus, the Steller Sea Lion and the Baikal Seal (Pinnipedia, Carnivora). [PDF]

PLoS ONE, 2016
Karyotype evolution in Carnivora is thoroughly studied by classical and molecular cytogenetics and supplemented by reconstructions of Ancestral Carnivora Karyotype (ACK).

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

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.

Karyotype Evolution in Birds: From Conventional Staining to Chromosome Painting. [PDF]

Genes (Basel), 2018
In the last few decades, there have been great efforts to reconstruct the phylogeny of Neoaves based mainly on DNA sequencing. Despite the importance of karyotype data in phylogenetic studies, especially with the advent of fluorescence in situ ...

Whole chromosome painting in two populations of the weakly electric fish Gymnotus mamiraua (Teleostei, Gymnotiformes) [PDF]

Scientific Reports
Techniques such as whole chromosome painting (WCP) have effectively expanded our understanding of the evolution and organization of the genome in fish, allowing us to obtain more detailed information about several evolutionary questions.

Microdissection and whole chromosome painting confirm karyotype transformation in cryptic species of the Lariophagus distinguendus (Förster, 1841) complex (Hymenoptera: Pteromalidae). [PDF]

PLoS One, 2019
Karyotypes of two cryptic species of parasitoid Hymenoptera with n = 5 and 6 belonging to the Lariophagus distinguendus (Förster, 1841) complex, which includes cosmopolitan parasitoids of coleopteran stored-product pests, were studied using glass-needle ...

The art of painting chromosome loops

Quantitative Plant Biology, 2023
How to get a metre of DNA into a tiny space while preserving its functional characteristics? This question seems easy to pose, but the answer is far from being trivial.

Chromosome painting and phylogenetic analysis suggest that the genus Lophostoma (Chiroptera, Phyllostomidae) is paraphyletic [PDF]

Scientific Reports, 2022
The subfamily Phyllostominae (Chiroptera, Phyllostomidae) comprises 10 genera of Microchiroptera bats from the Neotropics. The taxonomy of this group is controversial due to incongruities in the phylogenetic relationships evident from different datasets.

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 ...

Identification of the inverted chromosome 16 using chromosome painting [PDF]

British Journal of Haematology, 1999
The inverted chromosome 16 is commonly associated with acute myelomonocytic leukaemia (AML) M4 with bone marrow eosinophilia. Cytogenetic identification of the inverted chromosome 16 can be difficult. To help identify the inversion in bone marrow samples from patients referred for the diagnosis of AML‐M4, we applied the molecular cytogenetic technique ...

Quantifying Y chromosome loss in primary and metastatic prostate cancer by chromosome painting [PDF]

PLoS ONE
Somatic Y chromosome loss in hematopoietic cells is associated with higher mortality in men. However, the status of the Y chromosome in cancer tissue is not fully known due to technical limitations, such as difficulties in labelling and sequencing DNA ...
