“…Both characteristics are also responsible for the ability of DNA sequences to acquire secondary structures, such as cruciforms (stems or stems and loops, respectively). It has been postulated that these types of structures could be involved in recombination events (Israelewski, 1983;Higgins et al, 1988;Vogel et al, 1990) or in DNA amplification processes (Bigot et al, 1990;Oshima et al, 1992). In addition, these structures could be involved in chromatin organization as sites recognized by specific proteins, as in the case of HMG-I protein (Rodriguez-Alfageme et al, 1980).…”

This paper reports on the isolation and localization of the subtelomeric DraI satellite DNA in the Sparidae family. Gene cloning determined that the DraI satellite DNA is present in only 3 species (Pagrus pagrus, P. auriga, and Pagellus erythrinus) of the 10 Sparidae species analyzed. The results were confirmed by PCR amplification. This satellite DNA is located in a subtelomeric position in all 48 acrocentric chromosomes of these species. However, interstitial loci are also observed. Sequence analysis of monomers of this repetitive family indicates that the satellite DNA is associated with telomeric sequences, (TTAGGG)_n, in at least one species, P. erythrinus. This is the first direct demonstration of the existence of the consensus telomere sequences of vertebrates in fish. Likewise, this report also demonstrates that the ends of fish chromosomes have a structure similar to those of most eukaryote chromosomes, viz., telomere sequences and subtelomeric sequences associated by a boundary in which both types of sequences are interspersed. The recent origin of the DraI satellite DNA and its use as a phylogenetic marker is discussed.

“…They have been shown to increase recombination (Anderson and Roth 1978;Warren and Green 1985;Higgins et al 1988) andDNA amplification (Cohen andKopecko 1976). They are known to occur at sites of DNA breakage associated with gene conversion, nonhomologous recombination, and sister chromatid exchange (Israelewski 1983;Henthorn et al 1986;Krawinkel et al t986;Hyrien et al 1987;Vogel et al 1990) and may affect chromosome structure (Gilson et al 1986;Ohno 1990) or pairing (Sobell 1972;Doyle 1978).…”

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

et al. 1994

The Paternal-Sex-Ratio (PSR) chromosome of Nasonia vitripennis contains several families of repetitive DNAs that show significant sequence divergence but share two palindromic regions. This study reports on the analysis of junctions between two of these repetitive DNA families (psr2 and psr18). Three lambda clones that hybridized to both repeat families were isolated from PSR-genomic DNA libraries through multiple screenings and analyzed by Southern blots. Analysis of clones showed a region in which the two repeat types are interspersed, flanked by uniform blocks of each repeat type. PCR amplification of genomic DNA confirmed the contiguous arrangement of psr2 and psr18 on PSR and identified an additional junction region between these repeats that was not present in the lambda inserts. We isolated and sequenced 41 clones from the lambda inserts and genomic PCR products containing junction sequences. Sequence analysis showed that all transitions between psr2 and psr18 repeats occurred near one of the two palindromes. Based on the inheritance pattern of PSR, recombination between repeats on this chromosome must be mitotic (rather than meiotic) in origin. The occurrence of exchanges near the palindromes suggests that these sequences enhance recombination between repeat units. Rapid amplification of repetitive DNA may have been an important factor in the evolution of the PSR chromosome.

“…It has been hypothesized that secondary structures in the satellite DNA sequences, such as cruciforms, can be related to a tendency of the length of the repeat unit to fit the DNA organized in the core particle of the nucleosome (Israelewski, 1983;Fowler & Skinner, 1985). Tenebrio molitor satellite DNA has few possibilities to form cruciforms, although its length is very close (142 bp) to the DNA in the core particle (Ugarkovic et at., 1989).…”

Presence of highly repetitive DNA sequences in Tribolium flour-beetles

et al. 1993

Digestion of genomic DNA from seven species of Tribolium (Coleoptera) with Sau3AI, TaqI and C/al restriction enzymes shows the presence of remarkable amounts of highly repetitive DNA sequences in these species. In Tribolium freemani the sequences are tandemly repeated with a satellite monomer of 166 bp, A-T rich (70.5 per cent), representing 31 per cent of the total genome and located in centromeric chromosome areas as demonstrated by in situ hybridization. The sequence has the potential to form secondary structures such as stems or cruciforms due to the presence of frequent inverted repeats. Tribolium castaneum, T. anaphe and T. madens show homologous sequences to T freemani satellite DNA but T confusum, T audax, T brevicornis and other tenebrionid beetles, such as Tenebrio mo/itor and Misolampus goudoti, do not. A phylogenetic dendrogram, based on the homology and abundance of highly repetitive sequences deduced by dot-blot hybridization, chemotaxonomic and karyological characters, is proposed for the seven studied species of Tribo/ium.
