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.

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

Whole Genome Duplication of Intra- and Inter-chromosomes in the Tomato Genome
Journal of Genetics and Genomics, 2012Whole genome duplication (WGD) events have been proven to occur in the evolutionary history of most angiosperms. Tomato is considered a model species of the Solanaceae family. In this study, we describe the details of the evolutionary process of the tomato genome by detecting collinearity blocks and dating the WGD events on the tree of life by ...

Polyploidy in fungi: evolution after whole-genome duplication [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2012 Polyploidy is a major evolutionary process in eukaryotes—particularly in plants and, to a less extent, in animals, wherein several past and recent whole-genome duplication events have been described. Surprisingly, the incidence of polyploidy in other eukaryote kingdoms, particularly within fungi, remained largely disregarded by the scientific community

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 ...

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.

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,
