Speciation with gene flow

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Biodiversity is threatened by human activities, with extinction debt accumulating rapidly. Many of these activities change the connectivity of populations, fragmenting existing population systems or bringing previously isolated populations or species into contact.

Transcriptomic stress responses in Vaccinium spp. F1 hybrids: Implications for temperature‐resilient cranberry breeding using a crop wild relative

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Climate extremes threaten the sustainability of cranberry production, a culturally and economically important North American crop. This study demonstrates that wild cranberries (Vaccinium oxycoccos) harbor genetic variation that may enhance cold stress resilience when introduced into cultivated cranberry through hybridization.

Whole-Genome Duplication and Plant Macroevolution [PDF]

open access: yesTrends 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]

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 ...

Polyploidy in fungi: evolution after whole-genome duplication [PDF]

open access: yesProceedings 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

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?.

Whole-Genome Duplication and Yeast’s Fruitful Way of Life

Trends in Genetics, 2019
Studies 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

2012
Genetic 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.
