Sex And Heterochromatin: An Investigation Of Sexual Dimorphism In Drosophila Melanogaster
… Top2 also binds to a large block of satellite repeats present exclusively on the X chromosome (359bp repeats). I then discovered that deletion of X heterochromatin, which removes one copy of these satellite repeats, masculinizes heterochromatin in XX flies. Simultaneous loss of Top2 …

DNA DAMAGE AT TANDEM REPEATS GENERATES I-LOOPS THAT CAN BE EXCISED AS ECCDNA
… consequence of DNA damage also at centromeric α-satellite repeats. As in the case of telomeres, i-loop formation at centromeres was associated with an accumulation of eccDNA. I-loop and eccDNA accumulation was confirmed also by electron microscopy analysis of centromere-enriched samples, …

Contribution of Lsh to DNA methylation reprogramming in embryonic stem cell, epiblast stem cell and embryoid body model systems
… regulates DNA methylation at major and minor satellite repeats depending on cellular context, and that this regulation may involve a role for Lsh in maintenance of DNA methylation.

Molecular-cytogenetic analysis of repetitive sequences in genomes of Beta species and hybrids
… fluorescent in situ hybridization (FISH) of the satellite and dispersed repetitive sequences in wild and cultivated beet species and in their hybrids. New repetitive sequences were isolated from the B. procumbens genome. The AluI restriction satellite repeats pAp11 are 229-246 bp long and form …

Understanding Meiotic Recombination and Genomic Organisation of Plant Species
… megabase-long arrays of centromeric tandem repeats. While new long-read DNA sequencing technologies allow for more accurate assembly across the centromeres, methods for their annotation are also required. In this thesis, I present the development of Tandem Repeat Annotation and Structural …
