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 …

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 …

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

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 prevalence of autopolyploids in angiosperms has long been a subject of debate.
Müntzing (1936) and Darlington (1937) concluded that autopolyploids were common and …

Heterosis, also known as hybrid vigour, is widespread in plants and animals, but the
molecular bases for this phenomenon remain elusive. Recent studies in hybrids and …

The study of epigenetics in plants has a long and rich history, from initial descriptions of non-
Mendelian gene behaviors to seminal discoveries of chromatin-modifying proteins and …

Camelina sativa is an oilseed with desirable agronomic and oil-quality attributes for a viable
industrial oil platform crop. Here we generate the first chromosome-scale high-quality …

Hybrids such as maize (Zea mays) or domestic dog (Canis lupus familiaris) grow bigger and
stronger than their parents. This is also true for allopolyploids such as wheat (Triticum spp.) …

Allopolyploidy is an evolutionary and mechanistically intriguing process, in that it entails the
reconciliation of two or more sets of diverged genomes and regulatory interactions. In this …
