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
Genomic Organization of Repetitive DNA in Woodpeckers (Aves, Piciformes): Implications for Karyotype and ZW Sex Chromosome Differentiation.
Thays Duarte de Oliveira,Rafael Kretschmer,Natasha Avila Bertocchi,Tiago Marafiga Degrandi,Edivaldo Herculano Corrêa de Oliveira,Marcelo de Bello Cioffi,Analía Del Valle Garnero,Ricardo José Gunski +7 more
TL;DR: The results highlight the importance of microsatellite sequences in differentiation of sex chromosomes, and the accumulation of these sequences is probably responsible for the enlargement of the Z chromosome.
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
Chromosome Painting in Trogon s. surrucura (Aves, Trogoniformes) Reveals a Karyotype Derived by Chromosomal Fissions, Fusions, and Inversions.
Tiago Marafiga Degrandi,Analía Del Valle Garnero,Patricia C. M. O’Brien,Malcolm A. Ferguson-Smith,Rafael Kretschmer,Edivaldo Herculano Corrêa de Oliveira,Ricardo José Gunski +6 more
TL;DR: 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.
Journal ArticleDOI
Multiple sex chromosome system in penguins (Pygoscelis, Spheniscidae).
Ricardo José Gunski,Andrés Delgado Cañedo,Analía Del Valle Garnero,Mario Angel Ledesma,Néstor Coria,Diego Montalti,Tiago Marafiga Degrandi +6 more
TL;DR: The data presented in this work corroborate molecular phylogenetic proposals, supporting the monophyletic origin of penguins and intraspecific relations and made possible the identification of a high karyotype homology in Sphenisciformes.
