BackgroundThe accumulation of repetitive DNA during sex chromosome differentiation is a common feature of many eukaryotes and becomes more evident after recombination has been restricted or abolished. The accumulated repetitive sequences include multigene families, microsatellites, satellite DNAs and mobile elements, all of which are important for the structural remodeling of heterochromatin. In grasshoppers, derived sex chromosome systems, such as neo-XY♂/XX♀ and neo-X1X2Y♂/X1X1X2X2♀, are… 

Origin and Evolution of the Neo-Sex Chromosomes in Pamphagidae Grasshoppers through Chromosome Fusion and Following Heteromorphization

Details of the heteromorphization of the neo-sex chromosomes in species from both phylogenetic lineages of Pamphagidae grasshoppers are revealed and the hypothetical mechanism of the Neo-Y degradation was suggested.

Construction and Characterization of a Repetitive DNA Library in Parodontidae (Actinopterygii: Characiformes): A Genomic and Evolutionary Approach to the Degeneration of the W Sex Chromosome

It is demonstrated that an intensive invasion of TEs occurred during W sex chromosome differentiation in the Parodontidae, and the location of these elements on the chromosomes is important for understanding the function of these repetitive DNAs and for integrative studies with genome sequencing.

Repetitive DNA Sequences and Evolution of ZZ/ZW Sex Chromosomes in Characidium (Teleostei: Characiformes)

A comparative cytogenetic analysis in 13 Characidium species collected at different South American river basins confirmed the extensive karyotype diversity withinCharacidium in contrast with a conserved diploid chromosome number.

Construction and characterization of a repetitive DNA library in Parodontidae (Atinopterygii:Characiformes): a genomic and evolutionary approach to the degeneration of the w sex cromosome.

The presented data demonstrate that an intensive invasion of TEs occurred during W sex chromosome differentiation in the Parodontidae and are important for understanding the function of these repetitive DNAs and for integrative studies with genome sequencing.

Tracking the evolutionary pathway of sex chromosomes among fishes: characterizing the unique XX/XY1Y2 system in Hoplias malabaricus (Teleostei, Characiformes)

The present data suggested the origin of this unique XY1Y2 sex system, revealing evidences for the high level of plasticity of sex chromosome differentiation within the Erythrinidae.

High-throughput analysis of the satellitome revealed enormous diversity of satellite DNAs in the neo-Y chromosome of the cricket Eneoptera surinamensis

The results suggest possible involvement of satDNAs in genome increasing and in molecular differentiation of the neo-sex chromosomes in this species, contributing to the understanding of sex chromosome composition and evolution in Orthoptera.

Comparative analysis of C-heterochromatin, ribosomal and telomeric DNA markers in chromosomes of Pamphagidae grasshoppers from Morocco

Differences in the karyotypes of 10 species of the family Pamphagidae from Morocco revealed differences in the location and size of C-heterochromatin blocks and ribosomal DNA clusters, showing that karyotype divergences in this group is connected to structural chromosome rearrangements, but to the evolution of repetitive DNA.

Sex chromosome diversity in Armenian toad grasshoppers (Orthoptera, Acridoidea, Pamphagidae)

It is concluded that the different stages of neo-Y degradation revealed in the Pamphagidae species studied make the family a very promising and useful model for studying sex chromosome evolution.

Chromosomal Spreading of Microsatellites and (TTAGGG)n Sequences in the Characidium zebra and C. gomesi Genomes (Characiformes: Crenuchidae)

The distribution pattern of 18 different tandem repeats, including (GATA)n and (TTAGGG)n, in the genomes of C. zebra and C. gomesi were analyzed to explain the evolution of sex chromosomes in Characidium.

U1 snDNA clusters in grasshoppers: chromosomal dynamics and genomic organization

It is concluded in grasshoppers that the U1 snDNA had evolved under the birth-and-death model and that its intragenomic spread might be related with mobile elements.



Chromosomal Mapping of Repetitive DNAs in the Grasshopper Abracris flavolineata Reveal Possible Ancestry of the B Chromosome and H3 Histone Spreading

The organization of repetitive DNAs in the A complement and B chromosome system in the grasshopper species Abracris flavolineata is described using classical cytogenetic techniques and FISH analysis using probes for five multigene families, telomeric repeats and repetitive C0t-1 DNA fractions.

An accumulation of tandem DNA repeats on the Y chromosome in Silene latifolia during early stages of sex chromosome evolution

A novel tandem repeat called TRAYC, which has accumulated on the Y chromosome in S. latifolia, demonstrates that processes of satellite accumulation are at work even in this early stage of sex chromosome evolution and proposes a role for the centromere as a starting point for the cessation of recombination between the X and Y chromosomes.

A Gradual Process of Recombination Restriction in the Evolutionary History of the Sex Chromosomes in Dioecious Plants

Although the X-Y system evolved quite recently in Silene compared to mammals, the results suggest that similar processes have been at work in the evolution of sex chromosomes in plants and mammals, and shed some light on the molecular mechanisms suppressing recombination between X and Y chromosomes.

Effect of location, organization, and repeat-copy number in satellite-DNA evolution

This study demonstrates that molecular mechanisms of non-reciprocal exchange are key factors in the molecular drive process; the satellite DNAs in the non-recombining Y chromosomes show low rates of concerted evolution and intra-specific variability increase with no inter-specific divergence.

Chromosomal mapping of repetitive DNAs in the beetle Dichotomius geminatus provides the first evidence for an association of 5S rRNA and histone H3 genes in insects, and repetitive DNA similarity between the B chromosome and A complement

The chromosomal organization of repetitive DNA sequences, as well as the presence and characteristics of a B chromosome in two natural populations of Dichotomius geminatus (Coleoptera; Scarabaeidae) are reported using classical, chromosomal banding and molecular cytogenetic techniques.

The role of repetitive DNA in structure and evolution of sex chromosomes in plants

The occurrence and role of repetitive DNA in Y chromosome evolution in various species with a focus on dioecious plants is reviewed and the potential link between recombination and transposition in shaping genomes is discussed.

Neo-sex chromosome diversity in Neotropical melanopline grasshoppers (Melanoplinae, Acrididae)

The results showed different degrees of homology divergence between the neo-sex chromosomes and emphasize the plasticity of the chromosome complement of the Neotropical Melanoplinae to establish Robertsonian fusions and generate novel sex-chromosome systems.

Polymorphism of the nucleolus organizer region (NOR) on the putative sex chromosomes of Arctic char (Salvelinus alpinus) is not sex related

Repetitive DNAs (multicopy rDNA as in Arctic char or tandem repetitive DNA as in lake trout) appear to play important but different roles in the evolution of the sex chromosomes in these species.

The role of chromosomal rearrangements in the evolution of Silene latifolia sex chromosomes

It is suggested that the evolution of the S. latifolia Y chromosome has been accompanied by at least one paracentric and one pericentric inversion, and that chromosomal rearrangements are an integral part of sex chromosome evolution.

Evolution of sex chromosomes in insects.

The vast diversity of sex chromosome systems in insects--ranging from the classical male heterogametic XY system in Drosophila to ZW systems in Lepidoptera or mobile genes determining sex as found in house flies--implies that insects can serve as unique model systems to study various functional and evolutionary aspects of these different processes.
