Chromosome Painting in Neotropical Long- and Short-Tailed Parrots (Aves, Psittaciformes): Phylogeny and Proposal for a Putative Ancestral Karyotype for Tribe Arini
TLDR
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.
Identification of two independent X-autosome translocations in closely related mammalian (Proechimys) species
TLDR
Analysis of the origins of the XY1Y2 sex chromosome determination system in Proechimys species reveals that multiple translocations and inversions are responsible for the karyotype diversity of these species, and highlights the potential of these rodents as a model for studying sex chromosome evolution.
Chromosomal Evolution in the Phylogenetic Context: A Remarkable Karyotype Reorganization in Neotropical Parrot Myiopsitta monachus (Psittacidae)
TLDR
Results show that M. monachus probes generated by flow cytometry provide novel cytogenetic tools for the detection of avian chromosome rearrangements, since this species presents breakpoints that have not been described in other species.
Chromosome Painting Does Not Support a Sex Chromosome Turnover in Lacerta agilis Linnaeus, 1758
TLDR
The results reinforce the idea of the stability of the sex chromosomes and lack of evidence for sex-chromosome turnovers in known species of Lacertidae.
Cytogenetic Characterization of the Dwarf Oyster Ostrea stentina (Mollusca: Bivalvia) and Comparative Karyological Analysis within Ostreinae
TLDR
Ch Chromosome treatment with HaeIII produced specific banding patterns for all chromosomal pairs, confirming the efficiency of this restriction enzyme for chromosome banding in oysters.
Genetic diversity of two Portuguese populations of the pullet carpet shell Venerupis senegalensis, based on RAPD markers: contribution to a sustainable restocking program
TLDR
The high genetic variability of the natural population to be restocked makes it the preferential broodstock for aquaculture purposes, but the Ria de Aveiro population could also be a viable alternative, due to its genetic plasticity and the genetic similarity of both populations.
Marsupial chromosome DNA content and genome size assessed from flow karyotypes: invariable low autosomal GC content
TLDR
It is shown that Marsupial genomes are characterized by a low GC content invariable between autosomes and distinct from the higher GC content of the marsupial × chromosome, indicating that the genomes of these four species are 1–8% larger than human.
An Efficient Method for Genomic DNA Extraction from Different Molluscs Species
TLDR
This work describes an efficient method for molluscs genomic DNA extraction that was tested in several species from different orders, with different weight sample tissues, and demonstrated to be suitable for several downstream molecular techniques, such as PCR sequencing among others.
Conserved sex chromosomes and karyotype evolution in monitor lizards (Varanidae)
TLDR
Results show that differences in the morphology of the chromosome pairs 5–8 can be attributed to intrachromosomal rearrangements, which led to transitions between acrocentric and metacentric chromosomes in both directions.
New insights into sex chromosome evolution in anole lizards (Reptilia, Dactyloidae)
TLDR
It is demonstrated that different autosomes were involved in translocations with sex chromosomes in closely related lineages of anole lizards and that several sequential microautosome/sex chromosome fusions lead to a remarkable increase in size of Norops sagrei sex chromosomes.
