Substantial structural variation and repetitive DNA content contribute to intraspecific plastid genome evolution [PDF]
Background Plastids have highly conserved genomes in most land plants. However, in several families, plastid genomes exhibit high rates of nucleotide substitution and structural rearrangements among species.

Impact of Repetitive DNA Elements on Snake Genome Biology and Evolution [PDF]
The distinctive biology and unique evolutionary features of snakes make them fascinating model systems to elucidate how genomes evolve and how variation at the genomic level is interlinked with phenotypic-level evolution.

The mechanism of replication stalling and recovery within repetitive DNA [PDF]
DNA replication of repetitive sequences was recreated in a test tube using purified components. DNA alone was sufficient to induce stalling. Both stalling and recovery were dictated by the capacity of DNA to fold into unusual secondary structures.

Tigerfish designs oligonucleotide-based in situ hybridization probes targeting intervals of highly repetitive DNA at the scale of genomes [PDF]
Fluorescent in situ hybridization (FISH) is a powerful method for the targeted visualization of nucleic acids in their native contexts. Recent technological advances have leveraged computationally designed oligonucleotide (oligo) probes to interrogate ...

Potential of Herbariomics for Studying Repetitive DNA in Angiosperms
Repetitive DNA has an important role in angiosperm genomes and is relevant to our understanding of genome size variation, polyploidisation and genome dynamics more broadly.

Perm-seq: Mapping Protein-DNA Interactions in Segmental Duplication and Highly Repetitive Regions of Genomes with Prior-Enhanced Read Mapping. [PDF]
Segmental duplications and other highly repetitive regions of genomes contribute significantly to cells' regulatory programs. Advancements in next generation sequencing enabled genome-wide profiling of protein-DNA interactions by chromatin ...

Association of Chromosomal RNA with Repetitive DNA [PDF]
Chromosomal RNA, which is a component of the chromosomes of higher organisms, and whose participation is required for sequence-specific interaction of chromosomal proteins with chromosomal DNA, occurs in chromosomes bound to DNA. We have found that the DNA sequences to which chromosomal RNA binds are repetitive ones.

Repetitive Sequences in Plant Nuclear DNA: Types, Distribution, Evolution and Function
Repetitive DNA sequences are a major component of eukaryotic genomes and may account for up to 90% of the genome size. They can be divided into minisatellite, microsatellite and satellite sequences.
