Malaria Journal, 2023 Background The nuclear ribosomal RNA genes of Plasmodium parasites are assumed to evolve according to a birth-and-death model with new variants originating by duplication and others becoming deleted.

Concerted gene recruitment in early plant evolution [PDF]
Genome Biology, 2008 Abstract Background Horizontal gene transfer occurs frequently in prokaryotes and unicellular eukaryotes. Anciently acquired genes, if retained among descendants, might significantly affect the long-term evolution of the recipient lineage.

Frontiers in Plant Science, 2021 Molecular evolution of ribosomal DNA can be highly dynamic. Hundreds to thousands of copies in the genome are subject to concerted evolution, which homogenizes sequence variants to different degrees.

Concerted evolution of duplicate fla genes in Campylobacter [PDF]
Microbiology, 2000 Campylobacters have two similar copies (flaA and flaB) of their flagellin gene. It has been hypothesized that the two copies can serve for antigenic phase variation. Analysis of polymorphisms within aligned multiple DNA sequences of the Campylobacter flagellin genes revealed high pairwise homoplasy indexes between flaB/flaB pairs that were not observed

BMC Evolutionary Biology, 2005 Background The identification of sequence innovations in the genomes of mammals facilitates understanding of human gene function, as well as sheds light on the molecular mechanisms which underlie these changes.

Concerted Evolution Within the Drosophila dumpy Gene [PDF]
Genetics, 2007 Abstract We have determined by reverse Southern analysis and direct sequence comparisons that most of the dumpy gene has evolved in the dipteran and other insect orders by purifying selection acting on amino acid replacements. One region, however, is evolving rapidly due to unequal crossing over and/or gene conversion.

Detecting regular sound changes in linguistics as events of concerted evolution. [PDF]
Curr Biol, 2015 Concerted evolution is normally used to describe parallel changes at different sites in a genome, but it is also observed in languages where a specific phoneme changes to the same other phoneme in many words in the lexicon—a phenomenon known as regular sound change.

Evidence for Concerted and Mosaic Brain Evolution in Dragon Lizards [PDF]
Brain, Behavior and Evolution, 2017 The brain plays a critical role in a wide variety of functions including behaviour, perception, motor control, and homeostatic maintenance. Each function can undergo different selective pressures over the course of evolution, and as selection acts on the outputs of brain function, it necessarily alters the structure of the brain.

100 million years of multigene family evolution: origin and evolution of the avian MHC class IIB
BMC Genomics, 2017 Background Gene duplication has led to a most remarkable adaptation involved in vertebrates’ host-pathogen arms-race, the major histocompatibility complex (MHC).

The draft genome of Actinia tenebrosa reveals insights into toxin evolution
Ecology and Evolution, 2019 Sea anemones have a wide array of toxic compounds (peptide toxins found in their venom) which have potential uses as therapeutics. To date, the majority of studies characterizing toxins in sea anemones have been restricted to species from the superfamily,
