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.

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

PLoS Comput Biol
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 [PDF]

Frontiers 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.

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

Nat Commun
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 ...

The Genome Sequence of Alpine Megacarpaea delavayi Identifies Species-Specific Whole-Genome Duplication

Frontiers in Genetics, 2020
Megacarpaea delavayi (Brassicaceae), a plant found the high mountains of southwest China at high altitudes (3000–4800 m), is used as a vegetable or medicine. Here, we report a draft genome for this species. The assembly genome of M.

Gene count from target sequence capture places three whole genome duplication events in Hibiscus L. (Malvaceae)

BMC Ecology and Evolution, 2021
Background The great diversity in plant genome size and chromosome number is partly due to polyploidization (i.e. genome doubling events). The differences in genome size and chromosome number among diploid plant species can be a window into the ...

GPCR genes are preferentially retained after whole genome duplication. [PDF]

PLoS ONE, 2008
One of the most interesting questions in biology is whether certain pathways have been favored during evolution, and if so, what properties could cause such a preference.

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

PLoS 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 ...
