Inversions maintain differences between migratory phenotypes of a songbird

open access: yesNature Communications, 2023
Rearrangements in the genome are important for local adaptation and speciation but are often difficult to identify reliably. Here the authors show that rearrangements underlie large chromosome regions that separate differentially migratory willow ...

Genome rearrangements in Escherichia coli during de novo acquisition of resistance to a single antibiotic or two antibiotics successively

open access: yesBMC Genomics, 2018
Background The ability of bacteria to acquire resistance to antibiotics relies to a large extent on their capacity for genome modification. Prokaryotic genomes are highly plastic and can utilize horizontal gene transfer, point mutations, and gene ...

Investigating Potential Chromosomal Rearrangements during Laboratory Culture of Neisseria gonorrhoeae

open access: yesMicroorganisms, 2018
Comparisons of genome sequence data between different strains and isolates of Neisseria spp., such as Neisseria gonorrhoeae, reveal that over the evolutionary history of these organisms, large scale chromosomal rearrangements have occurred.

Interstitial deletion 4p15.32p16.1 and complex chromoplexy in a female proband with severe neurodevelopmental delay, growth failure and dysmorphism

open access: yesMolecular Cytogenetics, 2022
Complex chromosomal rearrangements involve the restructuring of genetic material within a single chromosome or across multiple chromosomes. These events can cause serious human disease by disrupting coding DNA and gene regulatory elements via deletions ...

Intergenomic rearrangements after polyploidization of Kengyilia thoroldiana (Poaceae: Triticeae) affected by environmental factors. [PDF]

open access: yesPLoS ONE, 2012
Polyploidization is a major evolutionary process. Approximately 70-75% species of Triticeae (Poaceae) are polyploids, involving 23 genomes. To investigate intergenomic rearrangements after polyploidization of Triticeae species and to determine the ...

Sorting by Multi-Cut Rearrangements

open access: yesAlgorithms, 2021
A multi-cut rearrangement of a string S is a string S′ obtained from S by an operation called k-cut rearrangement, that consists of (1) cutting S at a given number k of places in S, making S the concatenated string X1·X2·X3·…·Xk·Xk+1, where X1 and Xk+1 ...

Genomic rearrangements in prostate cancer [PDF]

open access: yesCurrent Opinion in Urology, 2015
Genomic instability is a fundamental feature of human cancer, leading to the activation of oncogenes and inactivation of tumor suppressors. In prostate cancer (PCA), structural genomic rearrangements, resulting in gene fusions, amplifications, and deletions, are a critical mechanism effecting these alterations.

Genomic Diversity and Clinical Variability in Pediatric Primary Cutaneous Anaplastic Large Cell Lymphoma: A Case Series

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Primary cutaneous anaplastic large cell lymphoma (pcALCL) is a rare pediatric CD30‐positive T‐cell lymphoproliferative disorder with an excellent prognosis, but its genomic drivers are poorly defined. We report three children with skin‐limited disease demonstrating striking molecular heterogeneity, including NPM::ALK, NUP214::FRK, and a novel ...

Implicit Transpositions in DCJ Scenarios

open access: yesFrontiers in Genetics, 2017
Genome rearrangements are large-scale evolutionary events that shuffle genomic architectures. The minimal number of such events between two genomes is often used in phylogenomic studies to measure the evolutionary distance between the genomes. Double-Cut-

Recombination-mediated genome rearrangements

open access: yesCurrent Opinion in Genetics & Development, 2021
Homologous recombination (HR) is a universal DNA double-strand break (DSB) repair pathway that uses an intact DNA molecule as a template. Signature HR reactions are homology search and DNA strand invasion catalyzed by the prototypical RecA-ssDNA filament (Rad51 and Dmc1 in eukaryotes), which produces heteroduplex DNA-containing joint molecules (JMs ...
