Origin of the Yeast Whole-Genome Duplication.

PLoS Biology, 2015
Whole-genome duplications (WGDs) are rare evolutionary events with profound consequences. They double an organism's genetic content, immediately creating a reproductive barrier between it and its ancestors and providing raw material for the divergence of

Interspecific introgression mediates adaptation to whole genome duplication [PDF]

Nature Communications, 2019
Whole genome duplication (WGD) presents new challenges to the establishment of optimal allelic combinations and to the meiotic machinery. Here, the authors show that adaptive gene flow from Arabidopsis arenosa could rescue the nascent A.

The collapse of gene complement following whole genome duplication [PDF]

BMC Genomics, 2010
Background Genome amplification through duplication or proliferation of transposable elements has its counterpart in genome reduction, by elimination of DNA or by gene inactivation. Whether loss is primarily due to excision of random length DNA fragments

Spontaneous whole-genome duplication restores fertility in interspecific hybrids [PDF]

Nature Communications, 2019
Hybridization across species can lead to offspring with reduced fertility. Here, the authors experimentally evolve yeast and show that whole-genome duplication during asexual reproduction can restore fertility in hybrids over a relatively short ...

Whole-Genome Duplication and Host Genotype Affect Rhizosphere Microbial Communities [PDF]

mSystems, 2022
The composition of microbial communities found in association with plants is influenced by host phenotype and genotype. However, the ways in which specific genetic architectures of host plants shape microbiomes are unknown.

ADARp150 counteracts whole genome duplication. [PDF]

Nucleic Acids Res
Abstract Impaired control of the G1/S checkpoint allows initiation of DNA replication under non-permissive conditions. Unscheduled S-phase entry is associated with DNA replication stress, demanding for other checkpoints or cellular pathways to maintain proliferation.

Evolution after Whole-Genome Duplication: Teleost MicroRNAs [PDF]

Molecular Biology and Evolution, 2021
AbstractMicroRNAs (miRNAs) are important gene expression regulators implicated in many biological processes, but we lack a global understanding of how miRNA genes evolve and contribute to developmental canalization and phenotypic diversification. Whole-genome duplication events likely provide a substrate for species divergence and phenotypic change by ...

Metabolic Adaptation after Whole Genome Duplication [PDF]

Molecular Biology and Evolution, 2009
Whole genome duplications (WGDs) have been hypothesized to be responsible for major transitions in evolution. However, the effects of WGD and subsequent gene loss on cellular behavior and metabolism are still poorly understood. Here we develop a genome scale evolutionary model to study the dynamics of gene loss and metabolic adaptation after WGD. Using

Whole-Genome Duplication and Plant Macroevolution [PDF]

Trends in Plant Science, 2018
Whole-genome duplication (WGD) is characteristic of almost all fundamental lineages of land plants. Unfortunately, the timings of WGD events are loosely constrained and hypotheses of evolutionary consequence are poorly formulated, making them difficult to test.
