“…The first reciprocal chromosome painting experiments between chicken and a bird of prey ( Leucopternis albicollis ) confirmed the occurrence of multiple fissions of GGA1, GGA2, GGA3, as well as reinforced the chromosome signature GGA1pter/GGA6 as a synapomorphy shared by four different Buteoninae species, illustrating the importance of the use of comparative chromosome painting in phylogenetic and evolutionary studies [10], [12].…”

Turdus rufiventris and Turdus albicollis, two songbirds belonging to the family Turdidae (Aves, Passeriformes) were studied by C-banding, 18S rDNA, as well as the use of whole chromosome probes derived from Gallus gallus (GGA) and Leucopternis albicollis (LAL). They showed very similar karyotypes, with 2n = 78 and the same pattern of distribution of heterochromatic blocks and hybridization patterns. However, the analysis of 18/28S rDNA has shown differences in the number of NOR-bearing chromosomes and ribosomal clusters. The hybridization pattern of GGA macrochromosomes was similar to the one found in songbirds studied by Fluorescent in situ hybridization, with fission of GGA 1 and GGA 4 chromosomes. In contrast, LAL chromosome paintings revealed a complex pattern of intrachromosomal rearrangements (paracentric and pericentric inversions) on chromosome 2, which corresponds to GGA1q. The first inversion changed the chromosomal morphology and the second and third inversions changed the order of chromosome segments. Karyotype analysis in Turdus revealed that this genus has derived characteristics in relation to the putative avian ancestral karyotype, highlighting the importance of using new tools for analysis of chromosomal evolution in birds, such as the probes derived from L. albicollis, which make it possible to identify intrachromosomal rearrangements not visible with the use of GGA chromosome painting solely.

“…Studies that have mapped the chromosomal location of 45S rDNA sites have shown considerable divergence among birds (Nishida-Umehara et al, 2007;Nishida et al, 2008Nishida et al, , 2013Nie et al, 2009;Tagliarini et al, 2009;de Oliveira et al, 2013;Kretschmer et al, 2014;. In Paleognathae birds, the 45S rDNA is normally found in a single microchromosome pair (Nishida-Umehara et al, 2007).…”

The distribution of 45S rDNA sites in bird chromosomes suggests multiple evolutionary histories

et al. 2020

The distribution of 45S rDNA cluster in avian karyotypes varies in different aspects, such as position, number of bearer chromosomes, and bearers being macro-or microchromosomes. The present study investigated the patterns of variation in the 45S rDNA-bearer chromosomes of birds in order to understand the evolutionary dynamics of the cluster configuration and its contribution to the evolution of bird karyotypes. A total of 73 bird species were analyzed, including both published data and species for which rDNA-FISH was conducted for the first time. In most birds, the 45S rDNA clusters were located in a single pair of microchromosomes. Hence, the location of 45S rDNA in macrochromosomes, observed only in Neognathae species, seems to be a derived state, probably the result of chromosomal fusion between microchromosomes and distinct macrochromosomes. Additionally, the 45S rDNA was observed in multiple microchromosomes in different branches of the bird phylogeny, suggesting recurrence of dispersion processeses, such as duplications and translocations. Overall, this study indicated that the redistribution of the 45S rDNA sites in bird chromosomes followed different evolutionary trajectories with respect to each lineage of the class Aves.

“…They were reported in several primates, cattle, reindeer, Chinese hamster, dog, and mouse [Di Berardino et al, 1983;Lin et al, 1984;Smeets and van de Klundert, 1990;Gripenberg et al, 1991;Stone and Stephens, 1993;Ruiz-Herrera et al, 2002;Helmrich et al, 2006]. There is abundant literature on the chromosomes of birds [Belterman and De Boer, 1984;de Oliveira et al, 2013;Nie et al, 2015], including that of BrdU treatments, but no fragile sites were noticed [Schmid et al, 1989;Nishida-Umehara et al, 1999]. In the course of control chromosome studies of our growing cell bank, we were surprised to detect multiple recurrent breakages in 2 chromosomes of a male blackbird Turdus merula Linnaeus, 1758 (Passeriformes: Turdidae) in fibroblast cultures treated by low doses of BrdU.…”

Amongst 15 bird species, representative of 7 orders, recurrent breakages evocating the presence of fragile sites were detected in the chromosomes of the 5 species belonging to Passeriformes. These breaks appeared when 5-bromodeoxyuridine (BrdU) was added to the cell culture medium at a dose inefficient for inducing chromosome structure alterations in other birds and mammals. They involved, similarly in male and female, 3 loci on the Z chromosome of 3 Turdus species (Turdidae). Labeling by BrdU antibody confirmed the correlation between BrdU incorporation into DNA and breakage, especially around and in the sites of breakage. Thus, 3 BrdU-sensitive fragile sites were present in the Z chromosomes of these birds. Three fragile sites were also detected at different locations in the Z chromosomes of the European robin (Erithacus rubecula, Muscicapidae), suggesting that a structural rearrangement occurred during the evolution of Turdidae and Muscicapidae. Chromosome banding confirmed this interpretation. Finally, in the more distantly related species Parus major (Paridae), the almost acrocentric Z chromosome displayed a single BrdU-sensitive fragile site in its short arm, and the W appeared to be pulverized by BrdU incorporation. Although it cannot be excluded that the BrdU-sensitive fragile sites may be involved in rearrangements, their conservation in many species, and possibly all Passeriformes, provides evidence that they do not constitute a pejorative character during evolution.
