Journal ArticleDOI
Introducing the Bird Chromosome Database: An Overview of Cytogenetic Studies in Birds.
Tiago Marafiga Degrandi,Suziane Alves Barcellos,Alice Lemos Costa,Analía Del Valle Garnero,Iris Hass,Ricardo José Gunski +5 more
TL;DR: The BCD will enable researchers to identify the main knowledge gaps in bird cytogenetics, including the most under-sampled groups, and make inferences on chromosomal homologies in phylogenetic studies.
Journal ArticleDOI
Evolution of Bird Sex Chromosomes Narrated by Repetitive Sequences: Unusual W Chromosome Enlargement in Gallinula melanops (Aves: Gruiformes: Rallidae).
Ricardo José Gunski,Rafael Kretschmer,Marcelo Santos de Souza,Ivanete de Oliveira Furo,Suziane Alves Barcellos,Alice Lemos Costa,Marcelo de Bello Cioffi,Edivaldo Herculano Corrêa de Oliveira,Analía Del Valle Garnero +8 more
TL;DR: The results show the involvement of heterochromatin and repetitive DNAs in the differentiation of the large W chromosome, and show an alternative scenario that highlights the plasticity that shapes the evolutionary history of bird sex chromosomes.
Journal ArticleDOI
The distribution of 45S rDNA sites in bird chromosomes suggests multiple evolutionary histories.
Tiago Marafiga Degrandi,Ricardo José Gunski,Analía Del Valle Garnero,Edivaldo Herculano Corrêa de Oliveira,Rafael Kretschmer,Marcelo Santos de Souza,Suziane Alves Barcellos,Iris Hass +7 more
TL;DR: 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.
Journal ArticleDOI
Karyotype Evolution and Distinct Evolutionary History of the W Chromosomes in Swallows (Aves, Passeriformes).
Suziane Alves Barcellos,Rafael Kretschmer,Marcelo Santos de Souza,Alice Lemos Costa,Tiago Marafiga Degrandi,Michelly S. dos Santos,Edivaldo Herculano Corrêa de Oliveira,Marcelo de Bello Cioffi,Ricardo José Gunski,Analía Del Valle Garnero +9 more
TL;DR: The data highlight the significant role that microsatellite sequences may play in sex chromosome differentiation and the observed enlargement in chromosome size might be explained by these high amounts of repetitive sequences.
Journal ArticleDOI
Novel insights into chromosome evolution of Charadriiformes: extensive genomic reshuffling in the wattled jacana (Jacana jacana, Charadriiformes, Jacanidae).
Rafael Kretschmer,Rafael Kretschmer,Marcelo Santos de Souza,Suziane Alves Barcellos,Tiago Marafiga Degrandi,Jorge C. Pereira,Patricia C. M. O’Brien,Malcolm A. Ferguson-Smith,Ricardo José Gunski,Analía Del Valle Garnero,Edivaldo Herculano Corrêa de Oliveira,Thales Renato Ochotorena de Freitas +11 more
TL;DR: It is shown that the chromosome evolution in Charadriiformes is complex and resulted in species with typical and atypical karyotypes, indicating that after divergence, each suborder has undergone different chromosome rearrangements.
