Evolution of tandem repeat satellite sequences in two closely related caenorhabditis species: Diminution of satellites in hermaphrodites
Subirana Torrent, Juan A.; Messeguer Peypoch, Xavier (2017-12-01)
Article
Accés obertThe availability of the genome sequence of the unisexual (male-female) Caenorhabditis nigoni offers an opportunity to compare its non-coding features with the related hermaphroditic species Caenorhabditis briggsae; to ... -
High evolutionary turnover of satellite families in Caenorhabditis
Subirana Torrent, Juan A.; Albà, M. Mar; Messeguer Peypoch, Xavier (2015-10-05)
Article
Accés obertBackground: The high density of tandem repeat sequences (satellites) in nematode genomes and the availability of genome sequences from several species in the group offer a unique opportunity to better understand the ... -
How long are long tandem repeats? A challenge for current methods of whole-genome sequence assembly: The case of satellites in caenorhabditis elegans
Subirana Torrent, Juan A.; Messeguer Peypoch, Xavier (2018-10-16)
Article
Accés obertRepetitive genome regions have been difficult to sequence, mainly because of the comparatively small size of the fragments used in assembly. Satellites or tandem repeats are very abundant in nematodes and offer an excellent ... -
Long non-coding RNAs as a source of new peptides
Ruiz Orera, Jorge; Messeguer Peypoch, Xavier; Subirana Torrent, Juan A.; Albà Soler, M. Mar (2014-09-16)
Article
Accés obertDeep transcriptome sequencing has revealed the existence of many transcripts that lack long or conserved open reading frames (ORFs) and which have been termed long non-coding RNAs (lncRNAs). The vast majority of lncRNAs ... -
Satellites in the prokaryote world
Subirana Torrent, Juan A.; Messeguer Peypoch, Xavier (2019-09-18)
Article
Accés obertBackground Satellites or tandem repeats are very abundant in many eukaryotic genomes. Occasionally they have been reported to be present in some prokaryotes, but to our knowledge there is no general comparative study ... -
Tandem repeats in Bacillus: Unique features and taxonomic distribution
Subirana Torrent, Juan A.; Messeguer Peypoch, Xavier (2021-05-20)
Article
Accés obertLittle is known about DNA tandem repeats across prokaryotes. We have recently described an enigmatic group of tandem repeats in bacterial genomes with a constant repeat size but variable sequence. These findings strongly ... -
The influence of Ni2+ and other ions on the trigonal structure of DNA
Acosta Reyes, Francisco Javier; Pagan, Mireia; Fonfría-Subirós, Elsa; Saperas Plana, Núria; Subirana Torrent, Juan A.; Campos López, Josefina de Lourdes (Wiley, 2021-04-13)
Article
Accés obertWe present a new structure of a DNA dodecamer obtained in the presence of Ni2+ ions. The DNA forms Ni-guanine cross-links between neighboring molecules. Our results show that an adequate dosage of Ni2+ may help to form ... -
Unique features of satellite DNA transcription in different tissues of Caenorhabditis elegans
Subirana Torrent, Juan A.; Messeguer Peypoch, Xavier (2023-02-03)
Article
Accés obertA large part of the genome is known to be transcribed as non-coding DNA including some tandem repeats (satellites) such as telomeric/centromeric satellites in different species. However, there has been no detailed study ... -
Unique features of tandem repeats in bacteria
Subirana Torrent, Juan A.; Messeguer Peypoch, Xavier (2020-08-24)
Article
Accés restringit per política de l'editorialDNA tandem repeats, or satellites, are well described in eukaryotic species, but little is known about their prevalence across prokaryotes. Here, we performed the most complete characterization to date of satellites in ... -
Visualization of sequence and structural features of genomes and chromosome fragments. Application to CpG islands, Alu sequences and whole genomes
Subirana Torrent, Juan A.; Anokian, Ezequiel (2011-03-01)
Article
Accés restringit per política de l'editorialA very simple new program is presented (G-SQUARES). It is useful in order to visualize the composition and basic structural features of whole genomes and selected chromosome regions. The frequency of all dimer and tetramer ...
