Gene retention, fractionation and subgenome differences in polyploid plants
All natural plant species are evolved from ancient polyploids. Polyloidization plays an
important role in plant genome evolution, species divergence and crop domestication. We …

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

Subgenome dominance in an interspecific hybrid, synthetic allopolyploid, and a 140-year-old naturally established neo-allopolyploid monkeyflower
Recent studies have shown that one of the parental subgenomes in ancient polyploids is
generally more dominant, having retained more genes and being more highly expressed, a …

The long and short of doubling down: polyploidy, epigenetics, and the temporal dynamics of genome fractionation
We consider the rapidly advancing discipline of plant evolutionary genomics, with a focus on
the evolution of polyploid genomes. In many lineages, polyploidy is followed by 'biased …
