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.

Gene duplication and evolution in recurring polyploidization–diploidization cycles in plants

open access: yesGenome Biology, 2019
Background The sharp increase of plant genome and transcriptome data provide valuable resources to investigate evolutionary consequences of gene duplication in a range of taxa, and unravel common principles underlying duplicate gene retention. Results We

Copy-number changes in evolution: rates, fitness effects and adaptive significance

open access: yesFrontiers in Genetics, 2013
Gene copy-number differences due to gene duplications and deletions are rampant in natural populations and play a crucial role in the evolution of genome complexity.

Parallel reorganization of protein function in the spindle checkpoint pathway through evolutionary paths in the fitness landscape that appear neutral in laboratory experiments. [PDF]

open access: yesPLoS Genetics, 2017
Regulatory networks often increase in complexity during evolution through gene duplication and divergence of component proteins. Two models that explain this increase in complexity are: 1) adaptive changes after gene duplication, such as resolution of ...

Revealing mammalian evolutionary relationships by comparative analysis of gene clusters [PDF]

open access: yes, 2012
Many software tools for comparative analysis of genomic sequence data have been released in recent decades. Despite this, it remains challenging to determine evolutionary relationships in gene clusters due to their complex histories involving ...

Efficient Exploration of the Space of Reconciled Gene Trees [PDF]

open access: yes, 2013
Gene trees record the combination of gene level events, such as duplication, transfer and loss, and species level events, such as speciation and extinction.

Complexity Insights of the Minimum Duplication Problem [PDF]

open access: yes, 2014
International audienceThe Minimum Duplication problem is a well-known problem in phylogenetics and comparative genomics. Given a set of gene trees, the Minimum Duplication problem asks for a species tree that induces the minimum number of gene ...

The 46, XX Ovotesticular Disorder of Sex Development With Xq27.1q27.2 Duplication Involving the SOX3 Gene: A Rare Case Report and Literature Review

open access: yesFrontiers in Pediatrics, 2021
Background: Very few reports are available on human XX ovotesticular disorder of sex development involving SOX3 gene duplication. Here we aim to present a rare case of SOX3 gene duplication in a person from the Chinese population who exhibits XX ...

The evolution of gene duplicates in angiosperms and the impact of protein-protein interactions and the mechanism of duplication [PDF]

open access: yes, 2019
Gene duplicates, generated through either whole genome duplication (WGD) or small-scale duplication (SSD), are prominent in angiosperms and are believed to play an important role in adaptation and in generating evolutionary novelty.

Altered patterns of gene duplication and differential gene gain and loss in fungal pathogens

open access: yesBMC Genomics, 2008
Background Duplication, followed by fixation or random loss of novel genes, contributes to genome evolution. Particular outcomes of duplication events are possibly associated with pathogenic life histories in fungi.
