Differential Retention of Metabolic Genes Following Whole-Genome Duplication [PDF]

open access: yesMolecular 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 ...

Genome duplication and gene loss affect the evolution of heat shock transcription factor genes in legumes. [PDF]

open access: yesPLoS ONE, 2014
Whole-genome duplication events (polyploidy events) and gene loss events have played important roles in the evolution of legumes. Here we show that the vast majority of Hsf gene duplications resulted from whole genome duplication events rather than ...

Horseshoe crab genomes reveal the evolution of genes and microRNAs after three rounds of whole genome duplication

open access: yesCommunications Biology, 2021
Wenyan Nong, Zhe Qu, Yiqian Li, Tom Barton-Owen, Annette Wong and colleagues provide genomes and small RNA transcriptomes for the mangrove horseshoe crab and the tri-spine horseshoe crab.

A model for biased fractionation after whole genome duplication [PDF]

open access: yesBMC 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 ...

Escape from preferential retention following repeated whole genome duplication in plants

open access: yesFrontiers in Plant Science, 2012
The well supported gene dosage hypothesis predicts that genes encoding proteins engaged in dose-sensitive interactions cannot be reduced back to single copies once all interacting partners are simultaneously duplicated in a whole genome duplication.

Parallel evolution of amphioxus and vertebrate small-scale gene duplications

open access: yesGenome Biology, 2022
Background Amphioxus are non-vertebrate chordates characterized by a slow morphological and molecular evolution. They share the basic chordate body-plan and genome organization with vertebrates but lack their 2R whole-genome duplications and their ...

Tetraodon genome confirms Takifugu findings : most fish are ancient polyploids [PDF]

open access: yes, 2004
An evolutionary hypothesis suggested by studies of the genome of the tiger pufferfish Takifugu rubripes has now been confirmed by comparison with the genome of a close relative, the spotted green pufferfish Tetraodon nigroviridis.

Constraining Whole-Genome Duplication Events in Geological Time

open access: yes, 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]

open access: yesGenome 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]

open access: yesPLoS 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.
