Whole-Genome Duplication and Yeast’s Fruitful Way of Life
Trends in Genetics, 2019Studies on the fate of Saccharomyces cerevisiae paralogous gene pairs that arose through a whole-genome duplication event have shown diversification of retained duplicated genes. Paralogous functional specialization often results in improved function and/or novel function that could contribute to the adaptation of the organism to a new lifestyle. Here,

The Role of Mutations in Whole Genome Duplication
2012Genetic mutation is an essential factor in the evolution of biological organisms and a driving force of phenotypical innovation. On rare occasions, nature takes a major evolutionary leap during which an organism's gene repertoire suddenly doubled.

Consequences of whole genome duplication for 2n pollen performance
Plant Reproduction, 2021The vegetative cell of the angiosperm male gametophyte (pollen) functions as a free-living, single-celled organism that both produces and transports sperm to egg. Whole-genome duplication (WGD) should have strong effects on pollen because of the haploid to diploid transition and because of both genetic and epigenetic effects on cell-level phenotypes ...

Evolutionary Significance of Whole-Genome Duplication
2012Whole-genome duplication (WGD) appears to be a widespread phenomenon, occurring in diverse taxa including many of the model organisms used in molecular, cellular, and developmental biology. It is therefore essential to understand the potential evolutionary consequences for individual duplicated genes, as well as for the lineage as a whole. For example,

Algebraic length distribution of sequence duplications in whole genomes
2011 Seventh International Conference on Natural Computation, 2011The field of comparative genomics relies upon inference of neutrality or selection from sequence conservation. Recent studies of exactly-conserved sequences have revealed an anomalous, algebraic distribution of conserved sequence lengths that is inconsistent with standard models of neutral evolution based solely on local mutation.

Whole-Genome Duplications in Pear and Apple
2019Whole-genome duplications (WGDs) are widespread in angiosperms, and are proposed to have contributed to angiosperm diversification. Pear (Pyrus) and apple (Malus) belong to the large and diverse Maleae tribe, and their genome sequences have extensive syntenic blocks covering much of the chromosomes, thus providing strong support for WGDs.

Increased glycolytic flux as an outcome of whole‐genome duplication in yeast
Molecular Systems Biology, 2007 After whole-genome duplication (WGD), deletions return most loci to single copy. However, duplicate loci may survive through selection for increased dosage. Here, we show how the WGD increased copy number of some glycolytic genes could have conferred an almost immediate selective advantage to an ancestor of Saccharomyces cerevisiae, providing a ...

Whole Genome Duplication in Plants: Implications for Evolutionary Analysis
2017The recurrent cycle of whole genome duplication (WGD) followed by massive duplicate gene loss (fractionation) differentiates plant evolutionary history from that of most other phylogenetic domains, where WGD has occurred relatively rarely, even on an evolutionary time scale. We discuss the mechanism of WGD and its biological consequences. We survey the

Whole-genome duplication as a key factor in crop domestication
Nature Plants, 2016Polyploidy is commonly thought to be associated with the domestication process because of its concurrence with agriculturally favourable traits and because it is widespread among the major plant crops(1-4). Furthermore, the genetic consequences of polyploidy(5-7) might have increased the adaptive plasticity of those plants, enabling successful ...
