Whole-genome duplication (WGD), or polyploidy, followed by gene loss and diploidization has long been recognized as an important evolutionary force in animals, fungi and other organisms, especially plants. The success of angiosperms has been attributed, in part, to innovations associated with gene or whole-genome duplications, but evidence for proposed ancient genome duplications pre-dating the divergence of monocots and eudicots remains equivocal in analyses of conserved gene order. Here we…

Early genome duplications in conifers and other seed plants
TLDR
Analysis of transcriptomes from 24 gymnosperms and 3 outgroups indicates that polyploidy has contributed to the evolution of conifers and other gymnos perms, contrary to previous genomic research that reported an absence of polyploidsy in the ancestry of contemporary gymnOSperms.
Ancient WGD events as drivers of key innovations in angiosperms.
Phylogenomic analysis of ancient genome duplications in the history of plants
TLDR
The overwhelming majority of well-resolved Vitis duplications were placed before the separation of rosids and asterids and after the split of monocots and eudicots, providing evidence for the WGD (γ) early in eudicot evolution.
Phylotranscriptomic Analyses Reveal Asymmetrical Gene Duplication Dynamics and Signatures of Ancient Polyploidy in Mints
TLDR
The results help disentangle WGD-derived gene duplicates from those produced by other mechanisms and illustrate the nonuniformity of duplication dynamics in mints, setting the stage for future investigations that explore their impacts on trait diversity and species diversification.
Widespread Whole Genome Duplications Contribute to Genome Complexity and Species Diversity in Angiosperms.
Recent advances in understanding the roles of whole genome duplications in evolution
TLDR
Genetic and biochemical studies in plants, yeasts and vertebrates suggest a paradigm in which different combinations of sister paralogues in the post-WGD regulatory networks are co-regulated under different conditions, which implies that simpler signalling pathways in the pre-W GD ancestors were converted via WGDs into multi-stranded parallelised networks.
A Phylogenomic Assessment of Ancient Polyploidy and Genome Evolution across the Poales
TLDR
Improved resolution of the timing of WGD events in monocot history provides evidence for the influence of polyploidization on functional evolution and species diversification.
Polyploidy-associated genome modifications during land plant evolution
TLDR
Pervasive polyploidy in angiosperms appears likely to be the major factor generating novel angiosperm genes and expanding some gene families, but most gene families lose most duplicated copies in a quasi-neutral process, and a few families are actively selected for single-copy status.
Evidence for an ancient whole genome duplication in the cycad lineage
TLDR
Remains of an ancient whole genome duplication in both cycad Encephalartos natalensis and Ginkgo biloba are identified and the most parsimonious explanation would be that this whole genome duplicate event was shared between both species and had occurred prior to their divergence, about 300 million years ago.
Integrated phylogenomic analyses reveal recurrent ancestral large-scale duplication events in mosses
TLDR
Four episodes of polyploidy events in the evolutionary past of Physcomitrella patens were unveiled, one of which was tightly associated with the early diversification of Bryopsida with an estimated age of ~87 million years.

Angiosperm genome comparisons reveal early polyploidy in the monocot lineage
TLDR
Evidence of additional duplication blocks of deeper hierarchy than the pancereal rho (ρ) duplication is presented, covering at least 20% of the cereal transcriptome, and it is suggested that it occurred early in the monocot lineage after its divergence from the eudicot clade.
The grapevine genome sequence suggests ancestral hexaploidization in major angiosperm phyla
TLDR
A high-quality draft of the genome sequence of grapevine is obtained from a highly homozygous genotype, revealing the contribution of three ancestral genomes to the grapevine haploid content and explaining the chronology of previously described whole-genome duplication events in the evolution of flowering plants.
Unraveling ancient hexaploidy through multiply-aligned angiosperm gene maps.
TLDR
It is shown that a shared ancient hexaploidy event (or perhaps two roughly concurrent genome fusions) can be inferred based on the sequences from several divergent plant genomes, laying the foundation for approximating the number and arrangement of genes in the last universal common ancestor of angiosperms.
Widespread Paleopolyploidy in Model Plant Species Inferred from Age Distributions of Duplicate Genes
TLDR
The unusual age profile of tandem gene duplications in Arabidopsis indicates that other scenarios, such as variation in the rate at which duplicated genes are deleted, must also be considered.
Plants with double genomes might have had a better chance to survive the Cretaceous–Tertiary extinction event
TLDR
It is proposed that polyploidization may have contributed to the survival and propagation of several plant lineages during or following the KT extinction event and might have been better able to adapt to the drastically changed environment 65 million years ago.
Evolution of gene function and regulatory control after whole-genome duplication: comparative analyses in vertebrates.
TLDR
It is concluded that the most significant consequence of WGD for vertebrate evolution has been to enable more-specialized regulatory control of development via the acquisition of novel spatiotemporal expression domains.
Widespread genome duplications throughout the history of flowering plants.
TLDR
Cross-species sequence divergence estimates suggest that synonymous substitution rates in the basal angiosperms are less than half those previously reported for core eudicots and members of Poaceae, and lower substitution rates permit inference of older duplication events.

Origin and Early Evolution of Angiosperms
TLDR
Analyses of morphological and molecular data reveal a revised “anthophyte clade” consisting of the fossils glossopterids, Pentoxylon, Bennettitales, and Caytonia as sister to angiosperms, indicating that polyploidy may have been an important catalyst in angiosperm evolution.
