Polyploidy: an evolutionary and ecological force in stressful times
Polyploidy has been hypothesized to be both an evolutionary dead-end and a source for
evolutionary innovation and species diversification. Although polyploid organisms …

The evolutionary significance of polyploidy
Y Van de Peer, E Mizrachi, K Marchal - Nature Reviews Genetics, 2017 - nature.com
Polyploidy, or the duplication of entire genomes, has been observed in prokaryotic and
eukaryotic organisms, and in somatic and germ cells. The consequences of polyploidization …

Polyploidy and genome evolution in plants
Plant genomes vary in size and complexity, fueled in part by processes of whole-genome
duplication (WGD; polyploidy) and subsequent genome evolution. Despite repeated …

Analysis of 41 plant genomes supports a wave of successful genome duplications in association with the Cretaceous–Paleogene boundary
Ancient whole-genome duplications (WGDs), also referred to as paleopolyploidizations,
have been reported in most evolutionary lineages. Their attributed role remains a major …

[HTML][HTML] Plant speciation through chromosome instability and ploidy change: cellular mechanisms, molecular factors and evolutionary relevance
N De Storme, A Mason - Current Plant Biology, 2014 - Elsevier
Plant speciation and diversification strongly rely on structural changes in the nuclear
genome, both at the whole ploidy and individual chromosome level. Phylogenetic …

[HTML][HTML] The 'seed-fern'Lepidopteris mass-produced the abnormal pollen Ricciisporites during the end-Triassic biotic crisis
The end-Triassic mass extinction (ETE;~ 201.6 million years ago) led to dramatic changes in
