  1. ...chromosome integrity, piRNA clusters encoding host defenses against selfish elements, and virtually the entire Y Chromosome. These regions, formed by highly similar tandem arrays, pose significant challenges for experimental and computational studies, impeding sequence-level descriptions essential...
  2. ....The Cys2-His2 zinc finger (ZNF) is a short nucleic acid binding domain widespread in eukaryotes. ZNFs are often arranged in tandemly repeated arrays, resulting in proteins with versatile nucleic acid binding ability (Wolfe et al. 2000; Klug 2010; Najafabadi et al. 2017). In metazoans, tandem-repeat ZNF...
  3. ...satellites can arise.Eukaryotic s are inundated with two types of repetitive sequences: transposable elements (TEs), which are dispersed by a variety of transposition mechanisms, and satellite sequences, which are tandemly repeated sequences that expand, contract, and are homogenized by recombination events...
  4. ...: In this window In a new window Figure 2. Number of hybridizing repetitive elements versus BAC clone size and complexity. BACs (652) from a high-density array were scored for the presence or absence of seven common retroelements (Huck, Prem-2, Opie, Grande, Prem-1, Zeon-1, and ANLI). ( A ) Repetitive elements...
  5. ...by their abundance in the HR Cot sequences. The extremely repetitive nature of these tandem arrays causes a major problem for the final assembly, as demonstrated by the fact that almost all identified instances of CNM or PO41 are located on the virtual chromosome ChrUn and are immediately flanked by gaps...
  6. ...dispersed throughout the The ribosomal-only contigs 19 to 29 (Fig. 2A) display a conserved structural pattern characterized by 45S rDNA genes (18S–5.8S–28S) flanked by a large array of tandemly repeated elements (Fig. 2B,C). We could identify other characteristic motifs: a 160 bp sequence at the 3′ end...
  7. ...intergenic regions and the genes themselves relative to rice. Intergenic regions The intergenic regions in all three chromosomes are composed of a mixture of low-copy noncoding sequences, also referred to as nonassigned intergenic sequences, and repetitive DNA elements. To separate these two categories, we...
  8. ...and subtelomeric repeats, and other repetitive elements such as the 70-bp repeat. Of these classes, the most common seems to be telomeric repeats, which appear to start close to the end of nonrepetitive regions (confirmed by the limited sequence data available for these regions) and show considerable heterogeneity...
  9. ...representing different Gossypium s and one phylogenetic outgroup View this table: In this window In a new window Table 2. Repetitive element copy number and density estimates Several conserved coding domains for diverse repetitive sequences were recovered from the WGS libraries when queried against Arabidopsis...
  10. ....Satellite DNAs (satDNAs) are the most abundant and rapidly evolving noncoding DNA of all eukaryotic s. In contrast to other groups of repetitive elements such as interspersed transposable elements (TEs), which are scattered throughout the , satDNAs are characterized by monomer sequences tandemly arranged...
