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

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 …

The large size and complexity of most fern genomes have hampered efforts to elucidate
fundamental aspects of fern biology and land plant evolution through genome-enabled …

Ancient duplication events and a high rate of retention of extant pairs of duplicate genes
have contributed to an abundance of duplicate genes in plant genomes. These duplicates …

Background The sharp increase of plant genome and transcriptome data provide valuable
resources to investigate evolutionary consequences of gene duplication in a range of taxa …

Budding yeasts (subphylum Saccharomycotina) are found in every biome and are as
genetically diverse as plants or animals. To understand budding yeast evolution, we …

Ancient whole-genome duplications (WGDs or polyploidy) are prevalent in plants, and some
WGDs occurred during the timing of severe global environmental changes. It has been …

Background Polyploidy or whole-genome duplication is now recognized as being present in
almost all lineages of higher plants, with multiple rounds of polyploidy occurring in most …

All natural plant species are evolved from ancient polyploids. Polyloidization plays an
important role in plant genome evolution, species divergence and crop domestication. We …

Premise of the Study Polyploidy or whole‐genome duplication (WGD) pervades the
evolutionary history of angiosperms. Despite extensive progress in our understanding of …
