Helitrons shaping the genomic architecture of Drosophila: enrichment of DINE-TR1 in α- and β-heterochromatin, satellite DNA emergence, and piRNA expression.
Dias GB, Heringer P, Svartman M, Kuhn GC. Dias GB, et al. Chromosome Res. 2015 Sep;23(3):597-613. doi: 10.1007/s10577-015-9480-x. Chromosome Res. 2015. PMID: 26408292 Review.

Kuhn GCS, Heringer P, Dias GB. Kuhn GCS, et al. Prog Mol Subcell Biol. 2021;60:27-56. doi: 10.1007/978-3-030-74889-0_2. Prog Mol Subcell Biol. 2021. PMID: 34386871
Since the discovery of satDNAs more than 50 years ago, species from the Drosophila genus have continuously been used as models to study several aspects of satDNA biology. These studies have been largely concentrated in D. melanogaster and closely related species from the S …

Concurrent Duplication of Drosophila Cid and Cenp-C Genes Resulted in Accelerated Evolution and Male Germline-Biased Expression of the New Copies.
Teixeira JR, Dias GB, Svartman M, Ruiz A, Kuhn GCS. Teixeira JR, et al. J Mol Evol. 2018 Jul;86(6):353-364. doi: 10.1007/s00239-018-9851-y. Epub 2018 Jun 23. J Mol Evol. 2018. PMID: 29934734
Particularly interesting are the highly diverged Cid1 and Cid5 paralogs of the Drosophila subgenus, which are probably present in over one thousand species. Given that CenH3 and Cenp-C likely co-evolve as a functional unit, we investigated the molecular evolution of Cenp-C …

They are thought to transpose via a rolling-circle mechanism, but no transposition assay has yet been conducted. We have recently characterized a group of Helitrons in Drosophila, named DINE-TR1, that display interesting features, including pronounced enrichment at beta-he …

We applied short-read sequencing and similarity clustering in order to perform a de novo identification of the most abundant satellite families in two Drosophila species from the virilis group: Drosophila virilis and D. americana, using the Tandem Repeat Analyzer (T …

Sequence analysis, chromosomal distribution and long-range organization show that rapid turnover of new and old pBuM satellite DNA repeats leads to different patterns of variation in seven species of the Drosophila buzzatii cluster.
Kuhn GC, Sene FM, Moreira-Filho O, Schwarzacher T, Heslop-Harrison JS. Kuhn GC, et al. Chromosome Res. 2008;16(2):307-24. doi: 10.1007/s10577-007-1195-1. Epub 2008 Feb 11. Chromosome Res. 2008. PMID: 18266060
We aimed to study patterns of variation and factors influencing the evolutionary dynamics of a satellite DNA, pBuM, in all seven Drosophila species from the buzzatii cluster (repleta group). We analyzed 117 alpha pBuM-1 (monomer length 190 bp) and 119 composite alpha/beta …

Guillén Y, et al. Genome Biol Evol. 2014 Dec 31;7(1):349-66. doi: 10.1093/gbe/evu291. Genome Biol Evol. 2014. PMID: 25552534 Free PMC article.
Cactophilic Drosophila species provide a valuable model to study gene-environment interactions and ecological adaptation. Drosophila buzzatii and Drosophila mojavensis are two cactophilic species that belong to the repleta group, but have very different geogr …
