“…Shared changes are usually considered to reflect spreading of sequence variants in the repetitive family in opposition to independent mutational events (Pages and Roizes 1984;Strachan, Webb, and Dover 1985). The remaining 20% of the mutations consist of single-nucleotide deletions and insertions.…”

A highly abundant satellite DNA comprising 17% of the Tribolium castaneum (Insecta, Coleoptera) genome was cloned and sequenced. The satellite monomer is 360 bp long, has a high A+T content of 73%, and lacks significant internal substructures. The sequence variability is 3.6%, essentially due to random distribution of single-point mutations. The satellite is evenly distributed in the regions of centromeric heterochromatin of all 20 chromosomes, as shown by fluorescent in situ hybridization. Comparison of T. castaneum satellite with those from three different but congeneric species reveals the highest sequence similarity of 47.1% with the satellite from the sibling species Tribolium freemani. The phylogenetic relationships among Tribolium species deduced from satellite sequence agree with those based on karyological, chemotaxonomic, and hybridization data. This indicates a parallel in the divergence of satellites and some genetic and cytogenetic characters. Despite low mutual sequence similarity, which makes them species-specific, Tribolium satellites have a common structural characteristic: a block of about 95% A+T content, 20 to 42 bp long, flanked at one side by an inverted repeat which can potentially form a thermodynamically stable dyad structure. Since similar structural features are found in centromeric DNA of Saccharomyces cerevisiae and Chironomus pallidivittatus, their possible importance in centromere function may be inferred.

“…It seems that the relative rate of mutational events compared to homogenization processes is similar for both T. obscurus satellites and higher than assumed for T. molitor satellite (Plohl et al 1992). Stretches of shared mutations in parts of some monomer variants can be observed in both T. obscurus, but not in T. molitor satellite, indicating that in the evolution of the former a process of gene conversion has played a role in inducing the occurrence of satellite subfamilies (Pages and Roizes 1984;Strachan et al 1985). Thus, it can be concluded that in these two closely related organisms, not only are satellite DNAs different, but also the influence and rate of different mutational processes involved in their evolution.…”

Two highly abundant satellite DNAs comprise 36% of the Tenebrio obscurus (Tenebrionidae, Coleoptera) genome. They are designated as satellite I and satellite II with the monomer length of 344 and 142 base pairs (bp), respectively. Both satellites differ in their nucleotide (nt) sequences, but the frequency of point mutations, well-conserved length of monomer variants, stretches of shared mutations characteristic for the process of gene conversion, and distribution of both satellites in regions of centromeric heterochromatin of all chromosomes indicate that the same evolutionary processes act on both of them with the same, or similar, rate. While satellite I shares no sequence similarity with any other known nt sequence, satellite II is 79.7% homologous with the highly abundant satellite from closely related Tenebrio molitor. Difference in the frequency of point mutations and absence of shared mutations indicating gene conversion strongly suggest that in these two closely related species mutational processes affecting satellite DNAs seem to be changed. Retarded electrophoretic mobility, due to sequence-induced curvature of DNA helix axis, was observed for T. obscurus satellite II, but not for satellite I. Although evolutionary processes act with different rates in T. obscurus and T. molitor satellites the monomer length and sequence-induced curvature are well preserved in both 142-bp satellites, as well as in, at the nt sequence level completely divergent, Palorus ratzeburgii (Tenebrionidae) satellite, indicating potential importance of these parameters in their evolution.

“…The domestic cattle (Bos taurus) genome harbours several distinct centromeric satDNA families (Macaya et al 1978) with interrelated evolutionary histories (Nijman & Lenstra 2001). The centromeric sequences, that include both tandem satellite arrays and dispersed repeats, reveal a diversified and complex structure and organisation (Pöschl & Streeck 1980;Gaillard et al 1981;Streeck 1981;Pagés & Roizés 1984;Plucienniczak et al 1985), as well as a widespread chromosomal distribution (Modi et al 1996(Modi et al , 2004Chaves et al 2000a reported that bovine satDNA sequences constitute around 25% of the total nuclear DNA content, a value in agreement with more recent analysis of high-volume genome sequencing data. The analysis and comparative study of these bovine satDNA families demonstrated that sequence alterations in association with DNA amplification/contraction events from a common ancestor could be implicated in the origin of the present satDNA families (Taparowsky & Gerbi 1982b).…”

Despite the many questions regarding satellite DNA sequences and their cellular roles, the evolutionary history of eukaryotic genomes seems to have been largely influenced by this dynamic and multifaceted genomic component. The bovine genome is highly rich in diverse satDNA sequences that differ in monomer sequence and length, complexity, chromosomal location and abundance, as well as in their sequences' evolutionary mechanisms. In the evolution of the Bovidae family, the genomes' repetitive fraction played a central role in karyotype reorganisation, and in the last few decades several studies have demonstrated and reinforced an association between centromeric satDNAs and the process of chromosome evolution in remodelling genomes of Bovidae species. Here, we review different aspects of the molecular nature and genome behaviour of all the satDNA families identified in the bovine genome, including their organisation, abundance, chromosome localisation, variation in sequence, and evolutionary history in the Bovidae family and in particular in the Bovinae subfamily, taking an integrative perspective. "Evolution and satDNA" can be addressed through two complementary views: the satDNA sequence evolution per se, and genome evolution promoted by the satDNA dynamism. SatDNA both provides phylogenetic information and is a critical genomic component that enables sequence and chromosome evolutionfeatures arising from its presence, absence or alteration.
