Gruiformes is a group with phylogenetic issues. Recent studies based on mitochondrial and genomic DNA have proposed the existence of a core Gruiformes, consisting of five families: Heliornithidae, Aramidae, Gruidae, Psophiidae and Rallidae. Karyotype studies on these species are still scarce, either by conventional staining or molecular cytogenetics. Due to this, this study aimed to analyze the karyotype of two species (Aramides cajaneus and Psophia viridis) belonging to families Rallidae and…

Cytotaxonomy of Gallinula melanops (Gruiformes, Rallidae): Karyotype evolution and phylogenetic inference
The results show that G. melanops has the same chromosome rearrangements as described in Gallinula chloropus (Clade Fulica), including fission of ancestral chromosomes 4 and 5 of Gallus gallus (GGA), beyond the fusion between two of segments resultants of the GGA4/GGA5, also fusions between the chromosomes GGA6/G GA7.
Genetics and Molecular Biology
Nine well-supported lineages from the cis-Andean region are identified from sequences available in the BOLD dataset, which minimizes identification mistakes, unintentional crossings by aquaculture, and reduces natural stocks contamination.
The Plasticity of Genome Architecture
The origin of species and their adaptability to new environments is one of the main questions in biology and the search for solutions to this problem is under way.


Cytotaxonomy of Eurypyga helias (Gruiformes, Eurypygidae): First Karyotypic Description and Phylogenetic Proximity with Rynochetidae
The karyotype of the sunbittern is described for the first time, by classical and molecular cytogenetics, using whole chromosome probes derived from Gallus gallus and Leucopternis albicollis to suggest a close phylogenetic relationship between Eurypigidae and Rynochetidae, whose common ancestor was separated by the Gondwana vicariancy in South America and New Caledonia.
Chromosome mapping of the large elaenia (Elaenia spectabilis): evidence for a cytogenetic signature for passeriform birds?
The characterization of the karyotype of Elaenia spectabilis (Passeriformes, Tyrannidae) by means of classical and molecular cytogenetics suggests that the centric fission in GGA1, as well as the inversions observed in segments homologous to GGA 1q, appeared in the early history of Passeriforms because they could be detected in Oscine and Suboscine species.
A phylogenetic analysis of the Gruiformes (Aves) based on morphological characters, with an emphasis on the rails (Rallidae).
In the species–level analysis of modern Grues, special efforts were made to limit the analytical impacts of homoplasy related to flightlessness in a number of rallid lineages, and relationships among ‘crakes’ remain poorly resolved.
Chromosome Painting in Trogon s. surrucura (Aves, Trogoniformes) Reveals a Karyotype Derived by Chromosomal Fissions, Fusions, and Inversions
The aim of this study was to characterize the karyotype of Trogon surrucura surru cura by means of classical and molecular cytogenetics, and found a diploid chromosome number of 2n = 82, similar to most birds, with several derived features compared to chicken and the putative ancestral avian karyotypes.
Chromosomal Diversity and Karyotype Evolution in South American Macaws (Psittaciformes, Psittacidae)
Analyzing the karyotype of two species of macaws confirmed that despite apparent chromosomal similarity, macaws have very diverse karyotypes, which differ from each other not only by inversions and translocations as postulated before, but also by fissions and fusions.
Karyotypic evolution in the Galliformes: An examination of the process of karyotypic evolution by comparison of the molecular cytogenetic findings with the molecular phylogeny
The process of the evolutionary changes of macrochromosomes in the 13 species was in good accordance with the molecular phylogeny, and the ancestral karyotype of the Galliformes is represented.
Chromosome Painting in Neotropical Long- and Short-Tailed Parrots (Aves, Psittaciformes): Phylogeny and Proposal for a Putative Ancestral Karyotype for Tribe Arini
This work constructed homology maps of Pyrrhura frontalis and Amazona aestiva, belonging to the long- and short-tailed groups, to propose a putative ancestral karyotype for this group, and indicates that PFR retained a more basal karyotypes than long-tailed species previously studied, and AAE aMore basal kARYotype for Neotropical Psittacidae analyzed so far.
Comparative Cytogenetics of the Congo African Grey Parrot (Psittacus erithacus)
The observations suggest that Psittaciformes karyotypes have undergone more extensive evolutionary rearrangements compared to the majority of other avian genomes.
Synteny Conservation of Chicken Macrochromosomes 1–10 in Different Avian Lineages Revealed by Cross-Species Chromosome Painting
Inter-species chromosome painting demonstrates remarkable conservation of macrochromosomal synteny over 100 million years of avian evolution and suggests a predominant role for rearrangements within the gene-dense microchromosome complement in karyotypic diversification.
