Subfunctionalization versus neofunctionalization after whole-genome duplication [PDF]
Nature Genetics, 2017 The question of what is the predominant evolutionary fate of genes after duplication events has been hotly debated for decades1,2. Two recently published articles in Nature (Lienet al.3) and Nature Genetics (Braaschet al.4) investigated the regulatory fate of gene duplicates after the salmonid-specific (Ss4R) and teleost specific (Ts3R) whole genome ...

Novelty and Convergence in Adaptation to Whole Genome Duplication [PDF]
Molecular Biology and Evolution, 2021 AbstractWhole genome duplication (WGD) can promote adaptation but is disruptive to conserved processes, especially meiosis. Studies in Arabidopsis arenosa revealed a coordinated evolutionary response to WGD involving interacting proteins controlling meiotic crossovers, which are minimized in an autotetraploid (within-species polyploid) to avoid ...

Evolution After Whole-Genome Duplication: A Network Perspective [PDF]
G3 Genes|Genomes|Genetics, 2013 AbstractGene duplication plays an important role in the evolution of genomes and interactomes. Elucidating how evolution after gene duplication interplays at the sequence and network level is of great interest. In this work, we analyze a data set of gene pairs that arose through whole-genome duplication (WGD) in yeast.

Polyploidy in fungi: evolution after whole-genome duplication [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2012 Polyploidy is a major evolutionary process in eukaryotes—particularly in plants and, to a less extent, in animals, wherein several past and recent whole-genome duplication events have been described. Surprisingly, the incidence of polyploidy in other eukaryote kingdoms, particularly within fungi, remained largely disregarded by the scientific community

Differential Retention of Metabolic Genes Following Whole-Genome Duplication [PDF]
Molecular Biology and Evolution, 2009 Classical studies in Metabolic Control Theory have shown that metabolic fluxes usually exhibit little sensitivity to changes in individual enzyme activity, yet remain sensitive to global changes of all enzymes in a pathway. Therefore, little selective pressure is expected on the dosage or expression of individual metabolic genes, yet entire pathways ...

A model for biased fractionation after whole genome duplication [PDF]
BMC Genomics, 2012 Paralog reduction, the loss of duplicate genes after whole genome duplication (WGD) is a pervasive process. Whether this loss proceeds gene by gene or through deletion of multi-gene DNA segments is controversial, as is the question of fractionation bias, namely whether one homeologous chromosome is more vulnerable to gene deletion than the other.As a ...

Constraining Whole-Genome Duplication Events in Geological Time
, 2023 The timing of whole-genome duplication (WGD) events is crucial to understanding their role in evolution and underpins many hypotheses linking WGD to increased diversity and complexity. As such, means of estimating the timing of the WGD events relative to their macroevolutionary outcomes are of considerable importance. Molecular clock methods facilitate

Pigmentation Pathway Evolution after Whole-Genome Duplication in Fish [PDF]
Genome Biology and Evolution, 2009 Whole-genome duplications (WGDs) have occurred repeatedly in the vertebrate lineage, but their evolutionary significance for phenotypic evolution remains elusive. Here, we have investigated the impact of the fish-specific genome duplication (FSGD) on the evolution of pigmentation pathways in teleost fishes.

Genomic plasticity enables phenotypic variation of Pseudomonas syringae pv. tomato DC3000. [PDF]
PLoS ONE, 2014 Whole genome sequencing revealed the presence of a genomic anomaly in the region of 4.7 to 4.9 Mb of the Pseudomonas syringae pv. tomato (Pst) DC3000 genome.
