High-throughput analysis of the satellitome illuminates satellite DNA evolution
TLDR
The high-throughput analysis of satellite DNA content in the migratory locust by means of the bioinformatic analysis of Illumina reads with the RepeatExplorer and RepeatMasker programs is shown and the term “satellitome” is proposed for the whole collection of different satDNA families in a genome. Expand
Genomics of Ecological Adaptation in Cactophilic Drosophila
TLDR
Gene duplication analysis identified lineage-specific expanded families with functional annotations associated with proteolysis, zinc ion binding, chitin binding, sensory perception, ethanol tolerance, immunity, physiology, and reproduction that are promising candidates for explaining the adaptation of these species to their distinct ecological niches. Expand
Next generation sequencing and FISH reveal uneven and nonrandom microsatellite distribution in two grasshopper genomes
TLDR
The first thorough joint analysis of microsatellite motifs at both genomic and chromosomal levels in animal species, by a combination of 454 sequencing and fluorescent in situ hybridization (FISH) techniques performed on two grasshopper species, is reported. Expand
Satellitome landscape analysis of Megaleporinus macrocephalus (Teleostei, Anostomidae) reveals intense accumulation of satellite sequences on the heteromorphic sex chromosome
TLDR
An analysis conducted on the satellitome of Megaleporinus macrocephalus that focuses specifically on the satDNAs that have been shown to have higher abundances in females and are putatively located on the W chromosome in this species. Expand
Protein-coding genes in B chromosomes of the grasshopper Eyprepocnemis plorans
TLDR
Interestingly, the five active genes in the B chromosome code for functions related with cell division, which is the main arena where B chromosome destiny is played, suggesting that B chromosome evolutionary success can lie on its gene content. Expand
DNA Amount of X and B Chromosomes in the Grasshoppers Eyprepocnemis plorans and Locusta migratoria
TLDR
The utility of the present approach for estimatingX and B chromosome DNA amount in a variety of situations, and the meaning of the DNA amount estimates for X and B chromosomes in these 2 species are discussed. Expand
Quantitative sequence characterization for repetitive DNA content in the supernumerary chromosome of the migratory locust
TLDR
The quantitative composition in repetitive DNA for a supernumerary (B) chromosome, in the migratory locust, is reported by Illumina sequencing of genomic DNA from B-carrying and B-lacking individuals and DNA obtained from a microdissected B chromosome, as well as the physical mapping of some elements. Expand
Delimiting the Origin of a B Chromosome by FISH Mapping, Chromosome Painting and DNA Sequence Analysis in Astyanax paranae (Teleostei, Characiformes)
TLDR
The population hereby analysed showed a female-biased B chromosome presence suggesting that B chromosomes in this species could influence sex determinism, and the hypothesis that the B chromosome of A. paranae is an isochromosome is supported. Expand
Uncovering the Ancestry of B Chromosomes in Moenkhausia sanctaefilomenae (Teleostei, Characidae)
TLDR
To investigate the origin of these B chromosomes, a combination of molecular cytogenetic techniques, nucleotide sequence analysis and high-throughput sequencing showed that B chromosomes have not yet reached the Paranapanema River basin and are mitotically unstable. Expand
Satellite DNA content illuminates the ancestry of a supernumerary (B) chromosome
TLDR
Bioinformatic analysis revealed the presence of seeds for the two B-specific satDNAs in the A chromosomes, suggesting their massive amplification in the B chromosome after its origin, suggesting that intraspecifically arisen B chromosomes can harbor DNA sequences apparently being B- specific.
