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 …

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

Cultivated strawberry emerged from the hybridization of two wild octoploid species, both
descendants from the merger of four diploid progenitor species into a single nucleus more …

Background Despite the prevalence and recurrence of polyploidization in the speciation of
flowering plants, its impacts on crop intraspecific genome diversification are largely …

Most land plants are now known to be ancient polyploids that have rediploidized.
Diploidization involves many changes in genome organization that ultimately restore …

We have witnessed an explosion in our understanding of the evolution and structure of plant
genomes in recent years. Here, we highlight three important emergent realizations:(1) that …

For decades, transposable elements have been known to produce a wide variety of changes
in plant gene expression and function. This has led to the idea that transposable element …

An essay on how modern flowering plant genomes are derived from processes of repeated,
episodic whole-genome doubling, or polyploidy, is presented. Topics discussed include …

The Cucurbita genus contains several economically important species in the Cucurbitaceae
family. Here, we report high-quality genome sequences of C. maxima and C. moschata and …

Polyploidy, or whole genome multiplication, is ubiquitous among angiosperms. Many crop
species are relatively recent allopolyploids, resulting from interspecific hybridization and …
