Promoter evolution of mammalian gene duplicates

open access: yesBMC Biology, 2023
Background Gene duplication is thought to be a central process in evolution to gain new functions. The factors that dictate gene retention following duplication as well paralog gene divergence in sequence, expression and function have been extensively ...

Can Introns Stabilize Gene Duplication?

open access: yesBiology, 2022
Gene duplication is considered one of the most important events that determine the evolution of genomes. However, the neo-duplication condition of a given gene is particularly unstable due to recombination events. Several mechanisms have been proposed to

Gene duplicability of core genes is highly consistent across all angiosperms [PDF]

open access: yes, 2016
Gene duplication is an important mechanism for adding to genomic novelty. Hence, which genes undergo duplication and are preserved following duplication is an important question. It has been observed that gene duplicability, or the ability of genes to be

Acquisition of new function through gene duplication in the metallocarboxypeptidase family

open access: yesScientific Reports, 2023
Gene duplication is a key first step in the process of expanding the functionality of a multigene family. In order to better understand the process of gene duplication and its role in the formation of new enzymes, we investigated recent duplication ...

Profiling of gene duplication patterns of sequenced teleost genomes: evidence for rapid lineage-specific genome expansion mediated by recent tandem duplications

open access: yesBMC Genomics, 2012
Background Gene duplication has had a major impact on genome evolution. Localized (or tandem) duplication resulting from unequal crossing over and whole genome duplication are believed to be the two dominant mechanisms contributing to vertebrate genome ...

Horizontal transfer, not duplication, drives the expansion of protein families in prokaryotes. [PDF]

open access: yesPLoS Genetics, 2011
Gene duplication followed by neo- or sub-functionalization deeply impacts the evolution of protein families and is regarded as the main source of adaptive functional novelty in eukaryotes.

Magnetosome Gene Duplication as an Important Driver in the Evolution of Magnetotaxis in the Alphaproteobacteria [PDF]

open access: yes, 2019
The evolution of microbial magnetoreception (or magnetotaxis) is of great interest in the fields of microbiology, evolutionary biology, biophysics, geomicrobiology, and geochemistry.

Selection in the evolution of gene duplications [PDF]

open access: yesGenome Biology, 2002
Gene duplications have a major role in the evolution of new biological functions. Theoretical studies often assume that a duplication per se is selectively neutral and that, following a duplication, one of the gene copies is freed from purifying (stabilizing) selection, which creates the potential for evolution of a new function.In search of systematic

The roles of segmental and tandem gene duplication in the evolution of large gene families in Arabidopsis thaliana

open access: yesBMC Plant Biology, 2004
Background Most genes in Arabidopsis thaliana are members of gene families. How do the members of gene families arise, and how are gene family copy numbers maintained?

The Role of Retrotransposons in Gene Family Expansions: Insights from the Mouse \u3ci\u3eAbp\u3c/i\u3e Gene Family [PDF]

open access: yes, 2013
Background: Retrotransposons have been suggested to provide a substrate for non-allelic homologous recombination (NAHR) and thereby promote gene family expansion. Their precise role, however, is controversial.
