SummaryThe common cetacean highly repetitive DNA component was analyzed with respect to its evolution and value for establishing phylogenetic relationships. The repeat length of the component, which is tandemly organized, is ≈ 1750 by in all cetaceans except the delphinids, in which the repeat length is ≈ 1580 bp.The evolution of the component was studied after sequencing the component in different odontocetes representing the Delphinidae (delphinids), Monodontidae (narwhals), and Ziphiidae… 

Evolutionary characterization of a highly repetitive sequence identified from the false killer whale (Pseudorca crassidens).

We report here that a novel 1,869 bp repetitive sequence identified from the false killer whale (Pseudorca crassidens) could be a new molecular phylogenetic marker in cetaceans. Results of PCR

Preservation and High Sequence Conservation of Satellite DNAs Suggest Functional Constraints

It is demonstrated that the satellite DNA family PSUB, abundant in the beetle Palorus subdepressus, is distributed in a low number of copies among diverse taxa of Coleoptera (Insecta), some of them separated for an evolutionary period of up to 60 Myr.

Phylogenetic Relationships of the Sparidae Family (Pisces, Perciformes) Inferred from Satellite‐DNA

The phylogenetic relationships within the taxonomically controversial Sparidae family of fish are inferred using two satellite-DNA families as phylogenetic markers, indicating the existence of two separate lineages from a common ancestor, each one clearly defined by either satellite- DNA family.

Sequence organization and evolution, in all extant whalebone whales, of a DNA satellite with terminal chromosome localization

A neighborjoining comparison between the consensuses of all species suggests that the unique portion of the repeats evolves at a somewhat different rate in different lineages.

Conservation of pBuM–2 satellite DNA sequences among geographically isolated Drosophila gouveai populations from Brazil

The sequences and the cluster analysis of pBuM-2 monomers showed that this repetitive element is highly conserved among the six D. gouveai populations (97.8% similarity), indicating a slow rate of evolution of p BuM- 2 sequences at the population level.

A complete phylogeny of the whales, dolphins and even‐toed hoofed mammals (Cetartiodactyla)

The present species‐level tree of the Cetartiodactyla provides the first opportunity to examine comparative hypotheses across entirely aquatic and terrestrial species within a single mammalian order.

Analysis of Mitochondrial and Nuclear DNA Markers in Old Museum Sturgeons Yield Insights About the Species Existing in Western Europe: A. sturio, A. naccarii and A. oxyrinchus

It is shown that, in addition to Acipenser sturio, the only species previously believed to inhabit the rivers of Western Europe, two other species lived in these rivers, and the combined use of both types of markers has provided accurate genetic identification of these specimens and has overcome the problem of misinterpretation caused by hybridization and introgression.

Junctions between repetitive DNAs on the PSR chromosome of Nasonia vitripennis: Association of palindromes with recombination

Analysis of junctions between two repetitive DNA families of Nasonia vitripennis contains several families of repetitive DNAs that show significant sequence divergence but share two palindromic regions suggests that these sequences enhance recombination between repeat units.



Highly repetitive DNA in the Baleen whale generaBalaenoptera andMegaptera

Three non-cross-hybridizing highly repetitive DNA components were studied in six whalebone and two toothed whale species, and the hybridization patterns were species specific, indicating that it evolves considerably faster than the other two components.

Composition and chromosomal localization of cetacean highly repetitive DNA with special reference to the blue whale, Balaenoptera musculus

Three highly repetitive DNA components — the common cetacean component, the heavy (GC-rich) satellite and the light (AT-rich) satellite — were studied in the blue whale. Consensus sequences of the

Conservation of highly repetitive DNA in cetaceans

Two labelled restriction fragment probes from the DNA of the sei whale were hybridized to restricted DNA of cetacean species representing all extant families except the Eschrichtiidae, the gray whales, and the results are compatible with a common ancestry of odontocetes and mysticetes.

Characteristics of a conserved 1,579-bp highly repetitive component in the killer whale, Orcinus orca.

A tandemly organized, highly repetitive DNA component of the killer whale was sequenced and computer analysis of the sequence showed no linear repetition within the component, indicating that the 1,579-bp unit has not evolved by amplification of shorter repeats.

Concerted evolution of light satellite DNA in genus Mus implies amplification and homogenization of large blocks of repeats.

The results show species variations in both the amount and periodic structure of the repeating units, which suggests that families of related higher-order repeats developed in a common ancestor and were then amplified and/or deleted to different extents during the subsequent evolutionary period.

Conservation and chromosomal localization of DNA satellites in balenopterid whales

The data on the whale DNA satellites indicate that the quantitative evolution of the satellite DNA sequences preceded species divergence of the balenopterids and that the satellite sequences have remained relatively unaltered since the divergence took place.


A 30-year renaissance in research on fossil marine mammals has brought advances on several fronts and suggests potential directions for future study. Gingerich and Russell have described Pakicetus,

Concerted evolution of alpha satellite DNA: Evidence for species specificity and a general lack of sequence conservation among alphoid sequences of higher primates

The results indicate that the alpha satellite DNA family has evolved in a concerted manner, such that considerable sequence divergence is now evident among the alphoid sequences of closely related primate species.

Transition stages of molecular drive in multiple‐copy DNA families in Drosophila

Differences between the families in the relatively small number of variants at each transition stage and the greater number of fully homogenized and fixed variants between species of greater divergence indicate that the process of spread is rapid relative to the mutation rate and occurs at seemingly different constant rates for each family.

Chromosome-specific subsets of human alpha satellite DNA: Analysis of sequence divergence within and between chromosomal subsets and evidence for an ancestral pentameric repeat

Comparisons of nucleotide sequences from cloned representatives of the multimeric higher-order repeat units of human chromosomes 1, 11, 17, and X suggest that this pentameric repeat must have spread to these four chromosomal locations many millions of years ago, since which time evolution of the four, now chromosome-specific, alpha satellite subsets has been essentially independent.
