Evidence for an ancient whole genome duplication in the cycad lineage.

open access: yesPLoS ONE, 2017
Contrary to the many whole genome duplication events recorded for angiosperms (flowering plants), whole genome duplications in gymnosperms (non-flowering seed plants) seem to be much rarer.

Timing of whole genome duplication is associated with tumor-specific MHC-II depletion in serous ovarian cancer [PDF]

open access: yesNature Communications
Whole genome duplication is frequently observed in cancer, and its prevalence in our prior analysis of end-stage, homologous recombination deficient high grade serous ovarian cancer (almost 80% of samples) supports the notion that whole genome ...

Origin of the Yeast Whole-Genome Duplication.

open access: yesPLoS 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

Effect of Whole-Genome Duplication on the Evolutionary Rescue of Sterile Hybrid Monkeyflowers [PDF]

open access: yesPlant Communications, 2020
Hybridisation is a creative evolutionary force, increasing genomic diversity, and facilitating adaptation and even speciation. Hybrids often face significant challenges to become established, including reduced fertility arising from genomic ...

Ohno-miRNAs: miRNA pairs derived from whole-genome duplication. [PDF]

open access: yesPLoS Computational Biology
Two rounds of whole-genome duplication (WGD) occurred about 500 million years ago and played a major role in the evolution of the vertebrate genomes. Human genes derived from WGD are called "ohnologs".

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.

Two rounds of whole genome duplication in the ancestral vertebrate. [PDF]

open access: yesPLoS Biology, 2005
The hypothesis that the relatively large and complex vertebrate genome was created by two ancient, whole genome duplications has been hotly debated, but remains unresolved.

Interspecific introgression mediates adaptation to whole genome duplication [PDF]

open access: yesNature 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]

open access: yesBMC 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

Does hybridization between divergent progenitors drive whole‐genome duplication?

open access: yesMolecular Ecology, 2009
This is the peer reviewed version of the following article: BUGGS, R. J. A., SOLTIS, P. S. and SOLTIS, D. E. (2009), Does hybridization between divergent progenitors drive whole-genome duplication?.
