Slipped-Strand Mispairing at Noncontiguous Repeats in Poecilia reticulata: A Model for Minisatellite Birth [PDF]

Genetics, 2000
Abstract The standard slipped-strand mispairing (SSM) model for the formation of variable number tandem repeats (VNTRs) proposes that a few tandem repeats, produced by chance mutations, provide the “raw material” for VNTR expansion. However, this model is unlikely to explain the formation of VNTRs with long motifs (e.g., minisatellites),

Genetic epilepsies with myoclonic seizures: Mechanisms and syndromes

Epilepsia Open, EarlyView.
Abstract Genetic epilepsy with myoclonic seizures encompasses a heterogeneous spectrum of conditions, ranging from benign and self‐limiting forms to severe, progressive disorders. While their causes are diverse, a significant proportion stems from genetic abnormalities.

Molecular characterization of Coxiella burnetii isolates by infrequent restriction site-PCR and MLVA typing

BMC Microbiology, 2006
Background Coxiella burnetii, the causative agent of Q fever, has a wide host range. Few epidemiological tools are available, and they are often expensive or not easily standardized across laboratories. In this work, C.

Genetic analysis of the rare forest bryophyte Dicranum viride in the boreo‐nemoral zone near the northern distribution range limit

Nordic Journal of Botany, EarlyView.
Bryophytes are important forest ecosystem elements, being an integral part of biodiversity. Genetic studies contribute to bryophyte population ecology by helping to understand species historical distribution patterns and genetic diversity at different scales.

Minisatellite Isolation and Minisatellite Molecular Marker Development in Citrus limon (L.) Osbeck

Data
Minisatellites are widespread tandem DNA repeats in the genome with a monomer length of 10 to 100 bp. The high variability of minisatellite loci makes them attractive for the development of molecular markers.

First genome sequence of a European Alternaria brassicae isolate and genes involved in early development of alternaria leaf spot on Brassica juncea

Pest Management Science, EarlyView.
This article reports the first genome sequence of a UK Alternaria brassicae isolate. Dual RNA‐sequencing profiling of A. brassicae‐infected Brassica juncea leaves identified differentially expressed genes involved in pathogenicity and host response pathways in moderately resistant Sej‐2 (2) and moderately susceptible Pusa Jaikisan cultivars.

Terminal Restriction Fragments (TRF) Method to Analyze Telomere Lengths

Bio-Protocol, 2015
Chromosome ends - telomeres - are a focus of intensive research due to their importance for the maintenance of chromosome stability. Their shortening due to incomplete replication functions as a molecular clock counting the number of cell divisions, and ...

Structural characterization of supercoiled DNA containing a minisatellite repeat that has polypurine/polypyrimidine stretch [PDF]

Nucleic Acids Symposium Series, 2007
The pUC19 derivative pAL79 contains six tandem repeats of a 30-bp unit sequence. Supercoiled pAL79 molecules show aberrant electrophoretic mobility under acidic conditions, and microscopic analysis suggests pAL79 molecules conform to tight plectonemes when deposited on a substrate under acidic conditions.

Technologies for engineering repetitive DNA

Quantitative Biology, Volume 14, Issue 3, September 2026.
Abstract Repetitive DNA, a fundamental architectural element of genomes, is widespread across organisms and comprises about 54% of the human genome. With advances in long‐read sequencing and bioinformatics approaches, highly repetitive sequences can now be characterized in depth.

The architecture of the Plasmodiophora brassicae nuclear and mitochondrial genomes

Scientific Reports, 2019
Plasmodiophora brassicae is a soil-borne pathogen that attacks roots of cruciferous plants causing clubroot disease. The pathogen belongs to the Plasmodiophorida order in Phytomyxea. Here we used long-read SMRT technology to clarify the P.
