Recent years have seen a surge in plant genome sequencing projects and the comparison
of multiple related individuals. The high degree of genomic variation observed led to the …

Polyploidy, defined as the coexistence of three or more complete sets of chromosomes in an
organism's cells, is considered as a pivotal moving force in the evolutionary history of …

Gene duplications have long been recognized as a contributor to the evolution of genes with
new functions. Multiple copies of genes can result from tandem duplication, from …

INTRODUCTION Polyploidy, arising from whole-genome duplication or interspecific
hybridization, is ubiquitous across the plant and fungal kingdoms. The presence of highly …

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 …

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

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

Understanding the quantitative genetics of crops has been and will continue to be central to
maintaining and improving global food security. We outline four stages that plant breeding …

Plant breeding has traditionally relied on combining the genetic diversity present within a
species to develop combinations of alleles that provide desired traits. Epigenetic diversity …
