Concerted evolution in the ribosomal RNA cistron. [PDF]

open access: yesPLoS ONE, 2013

Mosaic and concerted evolution in the visual system of birds. [PDF]

open access: yesPLoS ONE, 2014
Two main models have been proposed to explain how the relative size of neural structures varies through evolution. In the mosaic evolution model, individual brain structures vary in size independently of each other, whereas in the concerted evolution ...

Extensive nrDNA ITS polymorphism in Lycium: Non-concerted evolution and the identification of pseudogenes [PDF]

open access: yesFrontiers in Plant Science, 2022
The internal transcribed spacer (ITS) is one of the most extensively sequenced molecular markers in plant systematics due to its generally concerted evolution.

Empirical evidence for concerted evolution in the 18S rDNA region of the planktonic diatom genus Chaetoceros [PDF]

open access: yesScientific Reports, 2021
Concerted evolution is a process of homogenisation of repetitive sequences within a genome through unequal crossing over and gene conversion. This homogenisation is never fully achieved because mutations always create new variants. Classically, concerted

Comparative synthesis of tandem repeats in the control region of Epinephelus mitogenomes (Peciformes: Epinephelidae) [PDF]

open access: yesGenetics and Molecular Biology
In this study, we analyzed the evolutionary patterns of tandem repeats in the mitochondrial Control Region (CR) of groupers of the genus Epinephelus.

Concerted Evolution of Duplicate Control Regions in the Mitochondria of Species of the Flatfish Family Bothidae (Teleostei: Pleuronectiformes). [PDF]

open access: yesPLoS ONE, 2015
Mitogenomes of flatfishes (Pleuronectiformes) exhibit the greatest diversity of gene rear-rangements in teleostean fishes. Duplicate control regions (CRs) have been found in the mito-genomes of two flatfishes, Samariscus latus (Samaridae) and Laeops ...

Multiple Ribosomal RNA Operons in Bacteria; Their Concerted Evolution and Potential Consequences on the Rate of Evolution of Their 16S rRNA [PDF]

open access: yesFrontiers in Microbiology, 2018
Bacterial species differ greatly in the number and location of the rRNA operons which may be present in the bacterial chromosomes and plasmids. Most bacterial species contain more than one ribosomal RNA operon copy in their genomes, with some species ...

The link between independent acquisition of intracellular gamma-endosymbionts and concerted evolution in Tremblaya princeps [PDF]

open access: yesFrontiers in Microbiology, 2015
Many insect species establish mutualistic symbiosis with intracellular bacteria that complement their unbalanced diets. The betaproteobacterium Candidatus Tremblaya maintains an ancient symbiosis with mealybugs (Hemiptera: Pseudococcidae), which are ...

Dosage sensitivity of RPL9 and concerted evolution of ribosomal protein genes in plants [PDF]

open access: yesFrontiers in Plant Science, 2015
The ribosome in higher eukaryotes is a large macromolecular complex composed of four rRNAs and eighty different ribosomal proteins. In plants, each ribosomal protein is encoded by multiple genes.

Mechanism of Deletion Removing All Dystrophin Exons in a Canine Model for DMD Implicates Concerted Evolution of X Chromosome Pseudogenes [PDF]

open access: yesMolecular Therapy: Methods & Clinical Development, 2017
Duchenne muscular dystrophy (DMD) is a lethal, X-linked, muscle-wasting disorder caused by mutations in the large, 2.4-Mb dystrophin gene. The majority of DMD-causing mutations are sporadic, multi-exon, frameshifting deletions, with the potential for ...
