Mechanisms of gene duplication and amplification. [PDF]

open access: yesCold Spring Harbor Perspectives in Biology, 2015
Changes in gene copy number are among the most frequent mutational events in all genomes and were among the mutations for which a physical basis was first known. Yet mechanisms of gene duplication remain uncertain because formation rates are difficult to

Gene duplication and neofunctionalization: POLR3G and POLR3GL [PDF]

open access: yesGenome Research, 2014
RNA polymerase III (Pol III) occurs in two versions, one containing the POLR3G subunit and the other the closely related POLR3GL subunit. It is not clear whether these two Pol III forms have the same function, in particular whether they recognize the ...

Evolution of Gene Duplication in Plants1[OPEN] [PDF]

open access: yesPlant Physiology, 2016
Ancient duplication events and a high rate of retention of extant pairs of duplicate genes have contributed to an abundance of duplicate genes in plant genomes. These duplicates have contributed to the evolution of novel functions, such as the production of floral structures, induction of disease resistance, and adaptation to stress.

Gene Complexity and Gene Duplicability [PDF]

open access: yesCurrent Biology, 2005
Eukaryotic genes are on average more complex than prokaryotic genes in terms of expression regulation, protein length, and protein-domain structure [1-5]. Eukaryotes are also known to have a higher rate of gene duplication than prokaryotes do [6, 7]. Because gene duplication is the primary source of new genes [], the average gene complexity in a genome

Expectations of Duplicate Gene Retention Under the Gene Duplicability Hypothesis

open access: yesBMC Ecology and Evolution, 2023
Abstract Background Gene duplication is an important process in evolution. What causes some genes to be retained after duplication and others to be lost is a process not well understood. The most prevalent theory is the gene duplicability hypothesis, that something about the function and number of interacting partners (number of subunits of ...

Patterns of gene evolution following duplications and speciations in vertebrates [PDF]

open access: yesPeerJ, 2020
Background Eukaryotic genes typically form independent evolutionary lineages through either speciation or gene duplication events. Generally, gene copies resulting from speciation events (orthologs) are expected to maintain similarity over time with ...

Phylogenetic analysis reveals an ancient gene duplication as the origin of the MdtABC efflux pump. [PDF]

open access: yes, 2020
The efflux pumps from the Resistance-Nodulation-Division family, RND, are main contributors to intrinsic antibiotic resistance in Gram-negative bacteria. Among this family, the MdtABC pump is unusual by having two inner membrane components.

Duplicate Genes Contribute to Variability in Abiotic Stress Resistance in Allopolyploid Wheat

open access: yesPlants, 2023
Gene duplication is a universal biological phenomenon that drives genomic variation and diversity, plays a crucial role in plant evolution, and contributes to innovations in genetic engineering and crop development.

Gene Dosage and Gene Duplicability [PDF]

open access: yesGenetics, 2008
Abstract The evolutionary process leading to the fixation of newly duplicated genes is not well understood. It was recently proposed that the fixation of duplicate genes is frequently driven by positive selection for increased gene dosage (i.e., the gene dosage hypothesis), because haploinsufficient genes were reported to have more ...

Phylogenomics: gene duplication, unrecognized paralogy and outgroup choice. [PDF]

open access: yesPLoS ONE, 2009
Comparative genomics has revealed the ubiquity of gene and genome duplication and subsequent gene loss. In the case of gene duplication and subsequent loss, gene trees can differ from species trees, thus frequent gene duplication poses a challenge for ...
