Gene fate after single whole-genome duplication in angiosperm

Multiple whole-genome duplications (WGDs) are found in most sequenced angiosperms. WGDs help plants to survive in extreme environments and contribute to phenotypic innovations. Duplicated genes following WGD often have different fates: They can quickly disappear again, be retained for long(er) periods, or subsequently undergo small-scale duplications. But why do different genes have different fates following a WGD? How can different expression, epigenetic regulation, and functional constraints be associated with these different gene fates following a WGD? To answer these questions requires a model plant with a single WGD during its evolutionary past.
